Ford F-150 - 1997-2003 :: V6 Start And Died In About 5 Seconds - IAC Buzzes
Jan 18, 2016
Here's what I have : 2003 F150xlt V6. about 65K miles.
Here's what happened : Drove it to the hardware store to pick up some stuff. Stopped in front of the garage. No abnormal indications during that trip at all. Decided to back to the garage and when I started it, it "ran" very rough and died in about 5 secs. Started again and chugged for about 2 or 3 secs. Tried a third time and would not run.
Here's what I've got : No CEL. all gauges indicate correctly. No anti theft blink. more than a 1/4 tank of fuel. in south central PA about at 35 degree day. parked level.
What I've checked : Wife turned the key on, I hear the fuel pump run a couple seconds with my ear in the rear wheel well. truck turns over fine. no start. turn the key off, about a two second buzz from the idle air control valve. when the key is turned on with my finger on the fuel pump relay, I feel it shift. I have pulled it and looked for corrosion. no problem. checked applicable fuses (visually).
I have tried to start with the IAC and MAF disconnected individually. tried to start it with a different key.
I have not : Banged on the tank to free up the pump. (I don't suspect it at this point)
I have not checked to see if there is fuel pressure at the fuel rail. Where is that schrader valve? I miss my books.
I have not verified that I have spark. What's the easiest way?
I have not modified my air intake in any way.
I'm headed out to a parts store tonight or walmart to get another scanner. I think my best clue here is the buzzing IAC. What's that mean?

Went to start my truck up about 3 hours ago to take my ol' lady to work. Turned it over and acted like the usual cold start. Well soon as I thought it was good to let the engine spin, it got to about 300-400 RPM and then died. So I shut the vent off and turned my head lights off (turned them on soon as I thought it was good), spun the engine again and when it hesitated once again I gave it some gas like you would on a carb (not pumping just gave it half throttle or so) brought up the engine to about 3K and it ran just fine.
I'm not sure if its the fuel filter (when the last time my dad even bothered to change it since he has done most of the work on it in the time we've had it) or if the fuel pump is going out for the 3rd time in the last 10 years. The last time the fuel pump went it was a bad Walker fuel pump. It was promptly replaced with a Bosch and has been going strong for the last 8 years or so.
If it is the fuel pump, my guess is either my dad is going to junk it or fix it. With it getting close to 260K miles its becoming warn out and showing its age. Been pretty dependable and will do just about anything you ask and it'll do it even if it takes a long time to get going.
The fuel lines are pretty rusty so if its the filter chances are we'll have to put in a new section of fuel line in. Its probably running close to 135K miles on it since it was last done. I've only started doing maintenance on it the last 6 years or so for the most part.

First of it's a 2003 with the 4.6. I replaced a bad alternator a couple months ago and all was fine. On the way home today the radio volume went quiet and all the dash gauges were dead. Truck died and wouldn't even try to start, no starter clicking or anything. A couple times the gauges did the "sweep" but still no start, not even a starter click. Barely even operated the hazard lights. Towed it home and hooked up the jumper cables to my 7.3 Excursion. Truck started right up and I left if hooked up for a couple minutes hoping to get enough charge in the battery to get it in the garage.
Unhooked the jumper cables, got in the truck and noticed the voltage gauge was reading nothing, tried to move it and it died. Hooked the jumper cables back up and let the Excursion charge it for about 5 minutes. Started, drove it to the garage (100ft) and backed it in. Noticed the voltage gauge was where it should be. Turned it off and back to run (didn't start) and the voltage gauge was reading good and it started right up.
Now, it doesn't appear that the battery or alternator is bad. Is there something else I should be looking at? I can take the alternator off and have it checked but don't want to go through the work if not needed to chase a ghost. Advance auto Tough One alternator BTW.

My niece has a 1999 F150 with a 4.6L engine. She was driving it down the road and it died and would not start. She called her husband, he went where she was, and when he got there, it started. She drove it home, and the next day, same thing. Died going down the road, no start, let it sit overnight, cranked like a new truck. Now it has died and will not start at all. They replaced the fuel pump. Nothing. When you turn on the key, the fuel pump runs continuously. If you pour fuel in the air filter, it will start. They checked all the fuses, nothing blown. When they try to hook it up to an OBD scanner, it does not work. No codes, nothing, it won;t pick it up.

On my 97, just had a new engine installed. Suddenly the Lo presser AC switch died. Now the Start Solenoid (I think) just clicks sometimes. Is this Solenoid on the Firewall the Start Solenoid?

1999 Ford F-150 V8 5.4L... The other day I was attempting to fix my 4wd. I discovered that the vacuum tube by the 4wd solenoid had become disconnected. I reconnected it and in an effort to see if my fix was successful, I drove my truck up one of the canyons nearby. I got to an area full of loose rock and popped my truck into 4wd. As soon as I began to drive, the truck started idling very rough and died. I attempted to restart it for the next few minutes unsuccessfully. I got it started once and it continued to idle rough for a few seconds and died. I have not been able to start it since. It turns over but will not crank. It is not throwing any error codes. What I have checked so far:
Spark plugs are working.
When turning the ignition into the ON position, I am able to hear the fuel pump working.
I have not seen any cracks in the vacuum hose.
All the fuses are still okay.
What the culprit may be?

I have a 97 7.3 ... I've had it about 2 months now and now it wont start! It will start and idle for 2 seconds then start knocking and die! I had a buzz test ran on it and all is good. I also checked my Icp and checked my uvch harness with my multimeter. Before this it would run ok but seemed like it had a miss and a lack of power. On start up if i didn't have it plugged in it would smoke white smoke horribly. I am thinking maybe my IDM. I need my truck for work .... I had it hooked up to a scanner and it said faulty IDM.

2000 5.4l lariat. My cylinder 1 for 2 years has been poping p0301code and has a rough idle at start for about 30 seconds. It also has a little white smoke for that 30seconds. new cop, new spark plug, new spark plug pig tail, swapped injectors to different cylinders multiple times to change code no luck. Compression dry and wet are at 200 and all cylinders are within10%. I had a dorman intake manifold installed 4 years ago and the code came a few years after. Im thinking intake manifold gasket is bad between cylinder 1 and the heater bypass tube allowing coolant to slowly leak down into the cylinder causing my rough start. I looked through the injector hole but could not tell. With all the info I have given is there any other places or things that it could be before I do a gasket replacement or is all my tests leading to the intake manifold gasket...

My 4.2L died all of a sudden, it cranks but won't start. Checked the harness side to coil packs, pos. signal but no neg. Tried a code reader keeps coming back link error. Does this mean PCM is fried?

Tried starting the truck, fired ran good for a couple seconds, then ran extremely rough for a couple seconds then died.
I did some research and changed the ICP because there was oil in the connector so even if it wasnt causing my issue i wanted to replace it.
Now I have the same issue but it will actually run a little longer and not stall. I thought it was fixed so i took it for a drive, after about 3 miles it bogged down and i was able to make it home with half throttle going about 30mph. Sounds almost like its running on half the cylinders. i unplugged the ICP and it continued to run that way.
I had done the 50cent mod a few years back with the peices from ford but i know the harnesses themselves can wear through so i checked the resistance between the center pin and the two pins to the right and left for both the injector harness and they had about 3ohms.
I am leaning towards an IPR but from the reading i have done it seams like most trucks will not restart after they die. I have AE so i am going to hook it up later today, just wanted some reccomendations on what to look at.
I also remember when i shut it off the unplug the ICP to see if it would clear up the needles on the gauges did a full sweep as if i disconnected the battery which i though was weird.

On my way to work this morning check engine light came on, diagnosis came up with 2 codes p2181 cooling system and p1516 intake changeover. went to leave work car started then died after about 5 seconds then wouldn't start. as of right now I am thinking that it might be the coolant temp sensor? That's not letting it start? the past week it has been getting bad gas mileage and a low idle.
Mods done giac chip now set at stock setting
APR exhaust and intake
107,xxx miles

This applies to a 2001 F-350 with 73,000 miles on the engine. Engine oil level is good, batteries charged, HPOP reservoir is full and passes Cody test with flying colors. Fuel pump runs for 20 seconds at key on. Start takes about 6 seconds. If I shut the key off and restart immediately it starts in under 2 seconds but if I wait about 30 seconds it's a 6 second start. Here is an AE that I ran on it, it has me stumped. FWIW it seems to start quicker when AE is hooked up. ?? An odd whir type of noise comes out from somewhere under the hood when I first turn the key on and when I clear the codes with AE.

My friend's 1997 4 cyl ranger died and won't start. Cranks fine with no codes on OBD2. Was running fine before it died.

My 2004 F-150 Heritage with the 4.6 was running great until yesterday. Went in the store and left it idling, when I came back out it had died. First time it has ever done this. I started it and it started right up but misses bad. Checked it out and found all 4 cylinders on the drivers side are dead. The check engine light is on and the overdrive off light on the shifter is on. It will start right up and everything else is fine, oil pressure, coolant, etc.

My temperature and compass display just died on me, I don't have an owners manual with the truck so I don't know if it's a fuse I need to replace or what I need to do to get it working again.

I have a F150 2001 6cyl. Other day was doing 75 on freeway and lost all power. I replaced fuel filter, and pump is humming good (was replaced 4 years ago) checked the Inertia Switch and checked all relays, but truck still wont fire. I checked spark first and that's good.

I recently purchased a 1997 F150 4.2 Liter. On the way home it started missing. Within the next few days it died on the side of the road. After towing home I found no spark. A few days later I t started but only for a few minuites and died. No spark, coil pack is new so I replaced the CKP and it started up. Drove it about 1/2 Mile and died again, No spark again. Not getting power to coil pack when I am turning it over. So in short, new coil pack and CKP sensor and no spark. If it sits for a few days it may start or it may not. But if it does it only runs for a short period and then no spark again.

My 2000 f150 with a 4.6 and just about 200,000 miles stumbled for a minute then died, no engine light came on. It wanted to restart and almost did a couple time's but no go. which leads me to believe it has spark. after about a 30min cool down it started and ran fine like nothing ever happened. Got me home. then the next day same thing died and started after it cooled. Has done this a few time's.
I had put a cheap O'riely fuel pump in it a couple years ago. but i hear if you run your gas tank low on gas a lot (which I do) the pump can get hot and you can toast it. Does the fuel pump is the issue or could i have another problem. And BTW in the past year I have cleaned the EGR port's on the throttle body, put a new egr valve, and fuel filter. And i checked the fuel pressure to had 40...

I have a '97 4.6L 4x4. I've had a few issues recently and am at wits end.
Symptoms: while pulling a boat at highway speed, the engine engine just died. After waiting about 20 minutes for a buddy to show up with a tow rope, it started up and ran fine...until I got home (10 miles). I parked and after approx 5 minutes of idling it died again. No CEL, and found no codes when scanned. 15 minutes pass, it fires up and works fine.
The next day, I hook the boat up again, dive to the lake, go fishing, drive home. Everything was fine. I unhook the boat and drive to work. Half way there my voltage gauge starts falling and 5 miles later all of my gauges end electric stuff dies. I drive two more miles to work and strange beep starts coming from under the dash on the passenger side (I think). After my 12 hour shift it starts and I start my 10 mile commute. Half way through I lose electrical power again but make it home. Now it doesn't have the juice to turn over.
Are these problems related, and what are the possible causes and cures? On an unrelated note, what's the easiest way to replace a rear leaf spring shackle?
