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 :: 2006 - Shifts Really Hard?
my wife has an 06 with 77,xxx miles on it. as far as i know there has never been any tranny upkeep done on the vehicle. we have owned the care for approx 15 months. it doesnt act up all the time. it will shift real hard into reverse, feels like it is popping into it real bad. then at times it feels like it slips very little going into overdrive. and at times it will pop when shifted into drive. it is hard to predict, i thought maybe when it was warmed up and the fluid was warm it might not do this, but it does. i know nothing about this thing, the dealer wants me to bring it in so they can plug it in?

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.

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 - Explorer :: 1999 - Hard To Start Occasionally
Yes, another thread on an explorer that occasionally has trouble starting. One cold morning the fuel pump would not operate. When turning the key to run the volts to the pump (with plug disconnected) was 8.6 for a second, then dropped to the 6v range. I took the inertia switch from the firewall and back probed the wire going to the fuel pump, getting 12 volts. I went back to the fuel tank and measured the voltage with the key in run position, and read battery voltage. The car started, and has not failed in 3 days. I know it will quit again. I was thinking of replacing the inertia switch and fuel pump relay.

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.

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...

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 :: 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.

View 3 RepliesFord - Explorer :: 2006 - Ticking Noise When First Start Up The Engine
Just a quick question, my 2006 4.6 explorer has a ticking noise when you first start it up. It lasts for about 10 seconds and goes away. Sounds like a valve tappet when the oil needs changed etc. It has been running 5-w-20 in it like the book says. I'm going to change it again and see if it works. Any luck changing to a different grade.10w-30?
View 2 RepliesFord F-150 (2004-2008) :: 2006 4.6L - Hard To Start When Its Below 50F Outside
I have a 2006 4.6L that's hard to start when it's relatively cold outside.
Normally, when it's warm outside, I can barely bump the starter, and it starts right up. But when it's cold outside, it usually takes 3 or 4 2-3 seconds of cranking before it starts. Even then, it has a really rough "about to die" idle, until about 10-15 seconds, and then it idles without a problem. Once it's running, it runs great.
It has 79k miles on it, and all I've done to it is put in a throttle body spacer, and a K&N filter. I've read a few posts from people that have had similar issues, that had K&N filters, but their problems have been more consistent. Mine only seems to happen when it's first started.
As far as I know, the plugs have never been changed, as with the COPs. I've heard about a vacuum line running to the throttle body may be the culprit, but haven't been able to find any more details on that, like where the line runs to, possible replacement part number for it, etc.
Ford - Explorer :: 2006 V8 - Airbag Light On The Dash Comes On Randomly After Start Up
I have a 2006 Explorer with the 4.6 liter V8.
The airbag light on the dash comes on randomly after start up. It lights up solid and does not flash a code. I hooked up my code reader to it and it shows no code as well.
As part of my observations I have noticed that the passenger air bag off light comes on and goes off even when the seat is empty.
Ford - Explorer :: 2006 - Battery Light On - Clicking Noise At Start Up?
I have a 2006 explorer v6 the battery light went on today? My wife said it made a clicking noise when trying to start the other day but the battery is pretty new does this mean my alternator is bad?
View 4 RepliesFord F-150 (2004-2008) :: 2006 V8 Cutting Out / Hard To Start?
I have an 06 F-150 4x4 with the 5.4L Flex Fuel V-8. The truck has 133,000 miles on it. This morning, the truck was very hard to start. It took me 4-5 times of cranking the engine for 30 seconds or more before it started. Once it starts, it idles fine. Out on the road, the engine cuts out and the truck bucks pretty hard. The truck doesn't die, and the issue is intermittent. I changed the fuel filter less that 10,000 miles ago. The Check Engine Light has NOT come on. What could my problem be?
View 7 RepliesFord 6.0L Power Stroke Diesel :: 2006 - Hesitates - Hard Start?
I have a 2006 f250 with a 6.0 and I am having some issues with a hesitation and lose of power. The hesitation is worse when under load and other times is not so bad. Also it is non existent at higher RPMs (2500 and up). I changed the egr valve 2 months ago and it seemed to fix the issue (95%) but now it is running bad again. I used Hot Shot oil additive 2,500 miles ago and I changed the fuel filters and changed to 5w 40 Rotella synthetic oil, nothing has changed. I had the FICM changed a year ago with new software updates, still didn't fix it 100%.
Now I am having a "hard" start issue. It takes a bit for the truck to turn over. My batteries are 12 months old and I just replaced the alternator so I am not sure how to proceed.
I did just buy a Scangauge II and I am still figuring out how to use it. It says there is no codes.
Ford Super Duty (1999-2016) :: 2006 - Hard Start - Won't Crank?
I've been having sporadic starting issues with my truck since the fall. I had the spark plugs changed but that did not work. The hard starts usually occur when the engine is hot....after filling gas or just running into the grocery store. The engine seems to turn over slowly the first try and won't start. The second or third try the engine turns over normally and the truck usually starts.
I just got back from a 90 minute drive and shut off the truck for 5 minutes and now it won't even turn over. My thought is that it can't be the battery....its been charging for 90 minutes. Headlights are strong, wipers work fast, fan blows hard. That being said I think alternator or battery can be ruled out?
Where do I look next? Starter? Is there a starter solenoid that could be defective?
