Ford F-150 - 1997-2003 :: 2001 - Engine Is Turning Over But Starting Intermittently
The past week or 2 I have had an intermittent starting problem. Engine is turning over but wont start, but after i wait a second it will start up. I listened to see if the fuel pump was running and heard the whine. I checked the battery and the starter voltage and it was all good. i primed the fuel pump a couple of times and it started up on the first crank of the ignition. The truck runs great when driving and idling, no misses or loss of power that i have felt or heard yet. I am thinking it is either the fuel pump is starting to go or maybe the fuel filter is getting a little clogged up. Like i said up above this is an intermittent problem and that is why I am confused. Its a 2001 F150 4.6 4X4 ....

Ok, did a quick search, found nothing. Is there a way to get CEL codes without a reader on '01 F150? I know the way on 80's stuff, is there on newer stuff?

I have a 2001 F150 XL, 2WD, 4.2L, Auto at work. It will intermittently crank but not start, also, my scan tool will sometimes not connect to the truck. The only code I ever get is 1 about not being able to connect to self diagnostics. I have narrowed it down to the PCM relay in the underhood power distribution module not turning on because it SOMETIMES only sees a 2 volt turn on signal instead of 12 volts. I have replaced the ignition switch on the steering column- initially I thought that took care of it.
But as I was about to put the meter away it did it again. If I remove and reinstall the diode that is in the PDM, sometimes more than once, I can get it to turn on. Are these diodes available from any one besides Ford? The wiring diagram in my Haynes manual is very generic and does not show the circuit from the ignition switch to the fuse box. Where can I find a GOOD and complete wiring diagram for free on the net so I can print it out and take it with me to work?
Ford F-150 - 1997-2003 :: 2001 V8 Not Starting - Only Click Once When Turn The Key
2001 F150 4.6 V8 Triton
Automatic
Battery Tests Good
Starter Tests Good - I saw it spin and come out at the testing station at Autozone
Ignition Relay (the one in the fusebox)- New (8mo.)
Switch on the firewall on passenger side of truck - New (8mo.)
Battery terminals/connectors - Tight, no movement, Cleaned within the last week.
Starter connections - cleaned within the last week.
I am having trouble with my truck not starting. The issue has been occurring on and off for over a year. Usually, it happens about once a month, regardless of weather.
I turn the key, and there is one click. Usually at this point, I can use one hand to gently pull the shifter "up" towards park and turn the key again and it will start. Recently it is not starting when I do this. I have tried many times, and have tried to start it in Neutral (is that even possible with an Automatic?).
With the key in the "ON" position, I go under the truck and jump the starter cellinoid. I am jumping the small post to the big post where th wire comes from the battery. I do not touch the post that the wire goes into the starter.
I am very confused because it starts just fine without fail and almost instantly when I jump the posts. It is drive-able this way, but I would like to resolve this issue, and resume using my key to start it since the issue doesn't seem to be resolving itself as it usually does.
A friend told me about the Ignition Starter Switch inside the Column. If I have time I will attempt to start the truck with a screw driver on the switch tonight to narrow down the issue.
Ford F-150 - 1997-2003 :: 2001 5.4L Truck Will Crank But Not Starting
I drive a 2001 ford f150 lariat 5.4L. My truck will crank but not start, i am getting complete spark, and have ran a full fuel pressure procedure, and am getting complete fuel pressure, there is no water in my gas, everything checks out how it should. I ran a test on my cluster and it showed a code that said i am not getting connection to computer to start. I removed the cluster and repaired all loose wires properly, and it still wont start! I have had many people look at it and they said it could still be a bad cluster.

2001 f 150 5.4 liter with it being code pops up saying cylinder one misfire, I've charge coil and spark plug ran great for awhile now starting to act up again. Got coil check and says still good and look at spark plug and looks still in good shape being just replace two weeks ago. It's running fine but if it sits over night and I get in and start it and begins to shake when I but it in drive and don't even need to move the truck just place it in drive with foot on break. I drive it awhile and it stops and runs fine?

My truck, the aforementioned 01 f150 5.4 has been running fine but has had the codes p0401 and p1740. I know what they both mean I just haven't fixed them yet. Today I went to move my truck and it wouldnt start. It turned over fine and would hit some but wouldn't start. Would the tcc solenoid be the cause of that? Also the reason my egr is throwing is because there is a line that is not connected but I have no clue where it connects to... Where is the best place to get diagrams for the egr system.

We sold a customer a 5.4l engine and he installed it and it idles just fine, but falls on its face when put under load. Truck is a 2001 f150 and is not around here. Cus gave me these codes:
P0135
P1130
P0174
P0308
P0351
P0352
P1131
From all I have found, it appears to be a lean condition and cop #1 and #2. All of these codes pop up all at once after r&r ing an engine? I am thinking bad intake gasket and possibly bad coils.
Ford F-150 - 1997-2003 :: 2001 5.4L Throwing Codes PO135 / PO155 / PO174 And PO171
I have a 01 f150 7700 with a 5.4L and its throwing codes po135, po155, po174, and po171. Here is the history, last year had same code and found it was a bad ELLBOW on pcv hose, replaced and that fixed it, I also had a crack on egr valve and I replaced that too. This Jan truck was running bad in the morning and I traced it to a bad idle air controller, replaced it. I got a code and guy said I had a bad pcv valve so I replaced it.
About 3 weeks ago check engine light came back on with the 4 codes listed above, I replaced both front o2 sensors, 250,000 mile so I thought that was it but came back same code, I took it to a local mechanic and he said that the intake gaskets need replaced, but he call me later and said I had no leaks on the intake and that he did find another vac leak. He didn't charge me anything and sent me on my way.
I drove the truck about 50 miles and same codes back, so to recap I have cleaned mad sensor, replaced both front o2 sensors, a new egr valve, a new idle air control, pcv valve, pcv hose and ELLBOW, don't know what to look at next. Any clues?
Ford F-150 - 1997-2003 :: Stall After Starting Engine
Been awhile since I've been on here...guess that's a good thing! Current problem...about a week ago my car stalled after starting it. I had been running errands all day so the engine was warm. Started fine, and then slowly died. My husband replaced the IAC valve. (My truck had this same problem 3 1/2 years ago...it was the IAC).
After replacing this time, it seemed to be fine. However today, again after running errands, the engine stalled slowly after I had started the engine. It seemed like it was trying to stay running, but then just slowly died. I tried starting again and it stayed running, so I was able to get home. It seemed to run fine while driving home. Also, no engine light has come on. Wondering what could be causing this. Don't want to get stranded somewhere.
Ford F-150 - 1997-2003 :: Engine Stalls When Reading Codes
I've got a 1997 F250 with a transmission problem that I've been trying to diagnose. The problem is I can't grab any codes from the truck. I took her to the transmission shop and they described to me the same problem I was having. Whenever I try reading codes with the engine off it fails, when I try reading codes with the engine on it stalls the engine. The transmission shop referred me to another shop that might be able to figure my problem out, but I'd like to leave that as a last resort. I've checked all fuses and relays and I have a new engine computer on order right now. However, I'd like to know if there are any other possibilities.
View 1 RepliesFord F-150 - 1997-2003 :: 2001 4.6L Keeps Turning Over But Not Starting / Fuel Pump Makes Noticeable Buzzing Sound
My 2001 4.6L F-150 has been sitting on the driveway, used once every 2 weeks or so for the last 3 yrs. I came to start it a few days ago and it kept turning over but not starting. The key security chip is working, battery is charged, all plugs are firing, fuel pump fuse and relay check good. When I turn the key to ON, sometimes I hear the fuel pump priming, other times it doesn't. The times it does prime, the truck fires right up.
The times it doesn't prime, engine won't start. When the pump does prime, and while the engine is running, the pump makes a noticeable buzzing sound, much louder than normal. When the pump primes. fuel pressure measures at 42psi in the ON position, 36psi with engine running, and 46psi with engine running and vacuum hose removed. I believe all these are within specs.
My question is this: Is it safe to assume that the pump is going bad and will eventually fail completely? My second question is (and I know this can be debated til the end of time) should I get the Motorcraft or aftermarket? I have Airtex, Spectra, Carter, and Delphi available locally.
Ford F-150 - 1997-2003 :: Not Starting / One Thud When Attempting To Turn The Engine Over
After replacing the battery and starter...as well as replacing the alternator (bench tested good), I'm still greeted with one 'thud' when attempting to turn the engine over. The battery light is one in the dash. I've been through this scenario with more than a couple vehicles that haven't started in the past. I do the normal check the battery, wires, alternator, fuses, and starter. Somewhere along that line...it always fixes the issue. Not so here. I have to admit that I'm at a loss at the moment.

Ford F-150 - 1997-2003 :: Engine Starting Pulling Down And Shaking Heavily?
So i drive a 2001 F150 4.6L and over the last couple of years it has started pulling down and shaking heavily. I have taken it to mechanics and it always gave a code as a miss. well we replaced the coils and the plugs and of course it still has the problem. finally we did a compression test and it shows that #3 and #5 have no compression and the mechanic said it was either a blown head gasket, a valve or a cracked head. it has 230K miles on it so i was wondering what your thoughts on it were and also if it would be cheaper just to swap the motor.
View 2 RepliesFord F-150 - 1997-2003 :: Misfire Error Codes And Check Engine Light
So I have been having some troubles with my 2003 F150 4.6L ... Truck has been running rough and the check engine light was on so I decided to get the codes read and I got back P0302 and P0304, which from what I understand is a misfire on cylinders 3 & 4. At the same time I got Ford to do a little diagnostic and this is what they wrote for me:
"The connector for the number 2 coil is broken and will not stay plugged on to the coil and the number 2 coil is not working / replaced the wire for the coil still running rough removed the coil and plug. the plug was very badly fuel soaked started the vehicle to see if there was spark at the plug. OK. Suspect either a injector issue or a compression issue cleaned the plug seems better. "
So of course they quoted me for the works. They say I should replace the coils, plugs, and injectors??? I am pretty mechanically inclined and think I could change these things myself since I am on a budget. One tech told me is that the plugs can seize in these engines often and could scrap the whole thing??? Seems a little weird. If that happens though what could I do?
Ford F-150 - 1997-2003 :: Engine Service Light - Codes P0171 And P0174
2001 F150 5.4L Triton Motor. Everything seemed o.k. then got the Engine Service Light. Checked with reader and above codes only appeared. Read numerous articles/videos and pulled the PCV hose/boot assembly and replaced the whole thing with oem part. Visually checked for disconnected tubing = none found. After this and with the new hose assembly in place I performed a reset. With the scanner still connected restarted engine and read values: ST FTRM1&2 = -.08~+2.3, both oxygen sensor voltages are varying and the LT FTRM1&2 hang around +26 and +28.
From what I understand the ST seems o.k. but the long term is WAY OUT OF WHACK. Started it up again and took carb cleaner spray and covered all the connections I could see = no change in engine rpm. No cracks in the air cleaner body. Big plug to the MAF was inserted and plugging the hole. I am thinking of making a smoke "machine" and trying that or removing the hoses from the throttle body and plugging the holes in the throttle body and see if that clears them up. IF it does then connect one by one and keep checking the values. Lot more work but I am at a loss.
Ford F-150 - 1997-2003 :: Check Engine Light Has Been On - Codes PO401 And PO446 Came Up
Ive got a question for all you code readers out there. My dreaded check engine light has been on for about a month. I bought a code reader recently and checked it out. Two codes come up; PO401 and PO446. What these mean. My book says "Exhaust Gas Recirc. Flow Insufficient Detected" and " Evaporative Emission Control System Vent Control Circuit Malfunction". Which sensors, location on vehicle, etc..... this is a 97 5.4L Expedition.

PCV hose/grommet was rotted out with 1 inch hole but supposedly he spent a long time tracking down the problem. It was located way in the back middle (like underneath the wiper blades area).

What known issues would do this but not turn engine light on? Motor sounds excellent and runs excellent. Previously it was missing and engine code come up as random misfire, misfire cylinder #2 and #4. I replaced the coil packs on 2 and 4 and erased the code and there was a 1000% difference. Ran excellent (still does).
However, a week later I noticed a subtle shake in the motor, and at idle it would stay at 1...maybe slowly chirp just above 1, and then sputter a little down to 1/2 rpm. It will do this and stay running, but sometimes it will cut off.
What are the possible things that you think it could be considering no check engine codes? (Bad motor?)
