Ford - Explorer :: 1999 - Hard Start Like Not Getting Enough Fuel
Hard start like it's not getting enough fuel then kicks in and runs great with no hesitations or issues and with plenty of power. Replaced fuel filter, nothing changed.
View 3 RepliesFord F-150 - 1997-2003 :: 4.2L V6 Hard To Start / Occasionally Running Rough And Losing Power
I recently bought a 4.2L V6 2003 F150 with only 20,350 original miles. This car belonged to an older gent who barely used it, then passed on about 3 years ago, and truck sat around barely used by anyone. When I picked it up I ran some Seafoam through the first two gas tanks as it was occasionally running rough and losing power. Since then truck has been running incredibly smooth, but in the last few days it is getting harder to start. If I pumped it two or three times it would start OK, but today I have had to pump it while cranking it to get it to start. ( the pumping may have nothing to do with it starting)
I am replacing the fuel filter in the next couple of days, as any accumulated junk that was in the tank or lines is now probably in the filter, but it seems that a badly clogged filter would also give me some problems running, and it runs really smooth once it starts. I get a pressure gauge, (I understand the rails have a pressure test port) what pressures should I expect at what moments?
Turn key on :
Crank engine :
I am brand new to the F150 and trucks in general.
Corvair - Turbo :: 1964 - Occasionally Stalls And Can Be Hard To Start
Our new '64 Corvair Turbo car had been running pretty smooth, but occasionally stalls and can be hard to start. There has been noticeable flooding out of the carb bowl (single barrel Carter going into turbo). It has an electric choke that seems to be working correctly. The choke butterfly is closed when cold and opens as it gets warm.
Friday we drove to next town and it ran perfectly smooth but stalled when we got there, was very hard to start and ran super rough all the way home. It would not idle, had to hand brake at stops to keep from dying. It was normal temprature (400 degrees). Choke was wide open.
The next morning I started it easy, choke on (closed), but when it got warm it stalled and died. Then flooded fuel out of bowl.
I am only guessing... but seem like carb is tuned to run cold with choke on and is either running terribly lean or rich once it is at temperature.
Ford - Explorer :: 2006 - Hard To Start?
It is a 2006 Explorer with the 4.0 and around 89,000 on the odometer. Around a couple weeks or so ago the wife said the explorer was hard to start one evening and it has been like that ever since. It cranks for about 5 seconds and then fires. So far it has started every time since this issue began. This is really the first issue we have ever had other than the radiator replacement a few years ago.
View 3 RepliesFord Super Duty (1999-2016) :: Shift Very Hard After Idle In Gear (stop At Signal) Occasionally?
So, in my 99 Bounder RV (F53 chassis), V10
I think it has a 4R100 transmission in it (I have not verified this).
I had the oil and filter changed about 10K ago.
Runs and shifts fine .... then I stop and idle with it in gear (say stopped in traffic for a few minutes).
Now the thing shifts super hard! I actually get rubber in all gears.
So I pull over, shut it off. Restart the unit and everything is fine again.
It does this very consistently!
I went to the local transmission shop. They said with 110K in an RV it could be anything and I should think about letting them rebuild it.
Now that is something I would do ... not diagnose a problem and just rebuild it. I thought a "professional" would actually look for the problem first.
I don't want to rebuild the transmission if there is small item that will fix this.
Explorer :: 1994 Ford Hard To Start After It Sits
I've replaced the fuel pump and filter, plugs and coolant temp sensor. It starts after I spray starter fluid in after a few times and cycle the key on to prime the line but is still hard to start. It runs fine and it seems that as long as the engine is warm or (guessing) fuel is still pressurized in the line it starts fine.

I am having a random hard start condition. it will happen once a week or with no rhyme or reason. It turns over real nice but does not start until the second or third trythe last time on third try i push accel pedal to floor and it started. This hasn't happen in a few day so I cant tell you if the accel pedal will always work.
View 9 RepliesFord - Explorer :: 1994 - Hard To Start Up / Just Won't Crank
We have a 94 ford explorer and every now and again it has issues on the start up. It will sound like it will want to crank over but just won't. If we wait 20 mins it will start up no problem. We have changed the fuel pump, fuel filter, ignition coil, and fuel pump relay but it still has this problem. Also occasionally the a/c blower wont turn on. Tonight it happened again and I pulled the fuel pump relay out and it was really hot, after it cooled down and was put back in the car started. I am beginning to think it maybe an overheating issue that is affecting the relays but am not sure. I was also wondering about changing out the relay box...
View 6 RepliesFord - Explorer :: 2005 - Idle Roughly - Hard Start?
I have a 2005 Ford Explorer 4wd with 4.0 SOHC 6 cyl Flex Fuel. For months the vehicle has idle rough and increasingly becoming difficult to start. I decicded to replace the spark plugs and wires hoping to solve this issue! gap set to 052. When I started the vehicle it went into engine fail safe mode and wrench light came on. I then replaced the TPS on the throttle body and had no diference (I may have installed incorrectly! when I put it on the armature felt like it broke free inside the sensor). DTC codes read P0223, P2106, P2110 and with P0122 pending, P0223 pdg, P2106 pdg, & 2110 pdg.
With the old tps installed and wiring harness disconnected the truck will start in fail safe mode, but will not start at all with wire harness connected. A volt meter reads at computer end of wire plug 3.69 volts at pin one (gray/red wire +) and pin three (gray/white wire -) with key to on but not running.
Ford - Explorer :: 2007 - Hard Start - Idles A Little Rough
After sitting engine cranks longer than it usually did before it starts. idles a little rough. engine light comes on after it been running about 30 sec for 1 min. after that seems to run fine.check codes po446 and p1633 always come up. if you let sit a bit with key on starts right up.replaced gas cap checked evap lines, and changed filter no luck. Did notice with lines off evap solenoid key off or on i can blow through it. that doesn't sound right.
Checked fuel pressure. key on jumps to 90psi then falls to 55psi and stays. turn off key and leaked off 10psi in 5 min.start engine while watching gauge does the same as when the key on except it falls to 30 to 35 psi and bounces between them. i think this is way low. What is the correct pressure? Shut off engine and drops to 20 in 5 min. Next I plugged line on test tee going to fuel rail and tested same results as key on. the convinced fuel pump was bad since regulator and check is there. replaced pump. problem still there.
Ford - Explorer :: 2006 - No DTCs / Hard Start / Rough Idle And Stalling
I'm a diesel mechanic and know my way around Powerstrokes, this 4.0 is not what I would usually work on, but I have a friend who has 2006 explorer 4.0L SOHC, someone told him he needed a motor with out explanation why, so I didn't want to see him get ripped off. The problem is it idles very rough, hard to start, and stalls. There's no DTCs , if you hold the accelerator slightly it will stay running, but once you let off it will either idle really bad and misfire or cut off, once pushing the accelerator the rpms raise very smoothly up til 3500 which is what I assume the rev limit is in nuetral.
I've done checks with focom and forscan, I was thinking possibly a bad fuel pump, while monitoring fuel pressure I see a range of 289 - 326 kpa with 26% fuel pump I guess duty cycle would be the correct term(once again I'm a diesel guy, and use to dealing with IPRs and Hpops) not sure if the desired fuel pressure is relevant on these but it always stays at 269kpa. I believe that equals out to 40-48psi while I believe this system is supposed to have somewhere in the range of 60 - 70, but I wouldn't expect to get a rough idle with no load with almost 50 psi of fuel pressure.
So with no DTCs Im baffled, and don't want to start wasting money just throwing parts at it. I've thought everything from fuel pressure sensor, to coil pack(replaced 4 months ago) to crank and cam sensors.
I did end up getting a code p106, but I believe this is because I didnt tighten the intake hose after checking the throttle bottle, I just slid it back on. out of the 4 days of testing first time I seen a code pop up besides unplugging some sensors here and there to make sure the pcm would actually register a dtc.
Ford - Explorer :: 2000 Won't Idle When Cold / Hard To Start And Keep The Engine Running
I have a 2000 Explorer W/4.0 SOHC engine. With summer nearly over and fall on the way, I need to figure out what is going on with my engine. This problem has been going on for the past 2 years. As the outdoor temperatures get cooler, the harder it is to start and keep the engine running. This starts happening around 65 ambient temperature, and gets worse as the temps drop. By 30, I can barely keep the engine running.
Odd thing is, all I have to do if the engine starts is, keep my foot on the pedal to keep the engine around 2000RPM, put it in gear and start driving. After about a mile or two, the engine runs normally, and will do so the rest of the day. So far I have cleaned the air flow sensor, replaced the IAC, replaced all the injector "O" rings, and cussed a lot. I smoke tested the engine and the only vacuum leak is a very small one at the EGR valve.
Ford 7.3L Power Stroke (1999-2003) :: 2002 Truck Occasionally Won't Start
So a few weeks back, i went to the store after work, came out and my truck just cranked and cranked but wouldn't turn over. I simply turned the key off and back on, waited for the WTS light to go out and she started up. I just blew it off, thinking i didn't wait long enough to start it.
Then, later that week i come out of a restaurant and it cranks and cranks but doesn't start. i tried turning the key off and on, waiting 30 seconds between em and still nothing. Then a few minutes later, i try again and she fires up, no problems and runs like a champ.
Well 2 fridays ago, I go out with some buddies, go to leave and it happens again. Cranks and cranks, but not starting. I got a ride to my place, grabbed a fuel filter, thinking maybe its clogged, it's been awhile since i changed it. I got back to my truck, and it started up fine, without changing the filter.
Then last night as i am out of town, 10 hours away from home it happens again. And i kept trying and trying and trying but it never wanted to start. I was about to submit my payment for the Uber back to my hotel when i decide to try it again and it fired right up.
Now I'm kind of afraid to drive anywhere and shut off my truck in fear of being stranded. What could be causing this? I've looked every where and havent found someone with the exact same problem, usually when i find a thread on turning over but not starting, the truck dies once it runs as well. Mine doesn't. when it starts, she runs great.
No smoke coming out the tail pipe when cranking.
WTS light comes on and off as it should.
Tach does not move, and it won't because it's a 2002.
Where to start, would the CPS cause it to act this way? It only seems to do it when the engine is warm.
Ford Super Duty (1999-2016) :: 2015 F250 Acts Like Almost Dead And Won't Start Occasionally
I'm having multiple electrical problems and not sure if all related or not but they started at the same time.
1) Occasionally (getting more frequent) truck acts like its almost dead and wont start, but if i remote start it cranks right up
2) Radio doesn't shut off when I open the door, but if i close it and open again it does
3) phone staying connected to bluetooth but its acting up when trying use phone for music
Pretty sure there is more but I cant think of them now.
Ford Super Duty (1999-2016) :: 2001 F250 - Crank But Occasionally Wouldn't Start On First Attempt
2001 F250 5.4 ... I'm losing my mind chasing a Gremlin. I've been having mostly intermittent starting issues with my truck. I've had the truck for a little over a year, after someone totaled my previous one.
It occasionally wouldn't start on the first attempt, but it got really bad in the last couple weeks.
I first thought it was a faulty inertia switch or wiring in that vicinity, as at one point after manually tripping and resetting the cutoff switch it would start, UNTIL I put the trim panel back. At this point I think that may have been a coincidence.
I eventually probed the switch and it tests as it should electrically.
I put in a new fuel filter and things were fine for several days, but it acted up again. That time was last Saturday. Got it to start and all was good until tonight. Now it won't go, and I've tried so many times that I can see the battery power is dropping.
Last Saturday I pulled the relays from behind the radio and cleaned 'em up real nice. Also, just to check another variable I swapped the two that matched.
I'm about ready to change the fuel pump, but I've heard so many people say they did that but the problem was something else. Not only will it costs hundreds of dollars, its cold out and we'll have to drop the tank in the driveway.
In addition to the relay, inertia switch and fuse, I have found some mention of faulty fuel pressure regulators causing issues. I'll pry the vacuum line off in the morning to see if I can detect fuel residue on the vacuum side. (There is some noticeable corrosion on the fuel rail in that area).
I REALLY want to make sure I rule everything else out before spending hours under the truck in freezing weather dropping the tank and changing the sending unit out.
On key-on there is a noise from the gas tank, but someone else listening described it as a click but no whirring.
I do hear the relay clicking behind the radio. (Also, I pulled them again tonight and put a meter to them. With 12V on the primary side, they click and the other side shows continuity on diode check, and about .2 Ohm on resistance mode.)
I went through a lot of trouble to get my spare out looking for the fuel control module before finding out my truck is about 3 years too old to have one too. What else to check?
Ford Super Duty (1999-2016) :: Hard To Start When Cold - White / Grey Smoke At Start Up?
Truck: 1999 Ford Truck F 350 4WD Super Duty V8-7.3L DSL Turbo VIN F
Problem: Especially when it is cold outside . . . The truck takes forever to start and while doing so a ton of white/grey smoke comes out of the exhaust.
My starting schema: Turn the key on have the gas pedal pushed to the floor until the "wait to start" light goes out. Then, I turn the key off and back on while still pressing the gas pedal all the way down. When the "wait to start" light goes out again I remove my foot from the pedal and try to start it. I never leave it cranking for more than 5-7 seconds. If, after trying this process several times I will not push the pedal in at all. Also, sometimes I will leave the pedal pushed in while I am cranking it over.
The truck used to start after a couple of tries but lately it won't start at all, even after 20 tries. Sometimes it will spin up for a second as if the engine gets going but then just doesn't continue running. When it is warm out it will usually start after a few tries but doesn't seem normal to me. After I first bought the truck(used) it would start up within half a second after turning the key.This all started after I had to fix an o-ring that was damaged on the top/back of the motor that was dumping all my oil out of the top/back of the motor.
Mercury - Sable :: 1999 V6 Occasionally Will Not Start
I have a '99 Mercury Sable with the 3.0 24 Valve DOHC V6. The car occasionally will not start. It only happens after the car has been driven and warmed up, shut off, and then an attempted restart. This problem has occurred in all sorts of temps. Sometimes it will start within 30 minutes, sometimes it takes overnight. But it will start. I have already replaced the fuel pump relay. Is the fuel pump needing to be replaced (b/c it is failing slowly), or is this problem located somewhere else?

My truck is vibrating and shaking when you go over 30. but occasionally stops. I replaced the whole rear end, rear shocks, rear brakes, rear drive shaft U- joints, rebalanced the rear tires( they needed that). at least that fixed the noise (grinding) from the rear end is gone but it is still vibrating.. Over $700 in it this week. at least i did the repairs myself and saved a bunch of money. But i am now stumped... I dont know it if is front end issues, transfer case issues, transmission issues....
View 4 RepliesFord - Explorer :: 2007 - Interior Lights Occasionally Come On While Driving
I just acquired a 2007 explorer and have a little issue where the interior lights occasionally come on while driving. Did a little investigation and found that when I wiggle the ignition key the lights come on. Also noticed that when vehicle is shut off and door is open, I can wiggle the key and the "key in ignition" chime is intermittent. I'm guessing I need a new ignition switch and have a few questions regarding replacement of the switch.
I'm assuming the ignition keys have the chip in them and was wondering if I will have to reprogram keys or the switch or whatever...And if reprogramming is necessary, is it something that I can do myself?? Also, it looks as if I can replace the switch separate of the ignition lock cylinder. Will just replacing the switch fix my problem or do I need to replace the lock cylinder tumbler assembly as well??
