92 F-150 5.0 I've been fighting with this problem for over a month, I can't figure out what the problem is. I went to the store the other day came back out and the truck would not start turned over but didn't start. Got it towed back to the house and and it started right up. Then the other day while I was driving the truck totally shut off on me, I waited about 15 min. and it started back up. So far I've replaced the Ignition Control Module along with a new fuel filter. After replacing all that I drove it around ALL day it seemed to fix the problem. Now it's starting to act up again doing the same thing. ANY help would be appreciated.

 

I have the same problem in an '89 5.0. Let me know if you figure it out! I am takin it in to see if they can figure out the prob.

 

The TFI module on side of distributor and the pick up coil inside the distributor were both very temperature prone for acting up.

 

^ +1. Also, may want to check the coil resistances against spec.

May wish to pull the computer codes to see if anything has been flagged.

 

Well I had some diagnostics done, they came up with all 3 of the fuel pumps being shot or going out. This makes sense to me due to the fact that it runs great for about 15 min, the stalls, and 15 min later you can start it back up. What is happening on my truck anyway, the fuel pumps are overheating then shutting off. They gave me an estimate of $1500. HAHAHAHAHA, I thought that was a joke, I can take it to another local guy and he said he would do it for half. Anyway, thanks for the input!

 

Could it be just a coolant temp sensor? Someone gave me a blazer once cause it was doing the same thing and they couldnt figure it out. It ran great for 15 to 20 minutes, then it would die and wouldnt start again until it cooled some. I replaced the temp sensor for like 10 bucks and it ran fine. It might be worth checking out?

 

To make a long story short I was down to the last part to replace that everyone recommended. The pickup coil inside the distributor, while removing the gear I cracked the shaft. I got a new distributor and was wondering if someone could walk me through on Installing the new one and getting it back in time.

 

Place #1 cylinder on TDC of compression stroke, to do this remove spark plug from #1 and turn engine over by hand, with air being expelled from plug hole continue untill piston is at top. Feel this with screwdriver touching top of piston. While at TDC, hold distributor and have rotor pointing to location of #1 tower and stall, as the distributor goes down into place it will rotate slightly, bottom line the rotor has to be at #1 tower of distributor cap and a tooth has to be in the center of the pick ups magnet. It sounds more complicated than it is, hardest issue will be the oil pump drive shaft engagement. It can prevent full engagement of distributor. Just have to keep wiggling and trying. Send me a PM, if need further description. Will check in later before going on trip for 4 days, leave at 4PM forum time.

 

JAYROCK I am having this same problem and just got done replacing the TFI module to no avail. Let me know what all you replaced and if it helped.

My 94 did the same thing and I finally found the problem. The plug connecting my distributor to the wiring harness was dirty and maybe a little corroded. The truck would die on me and so I would unplug and reconnect it and it would fire right back up. I got some electrical contact cleaner and cleaned both ends of the plug the best I could and then coated the female end with dielectric grease. It has not hickuped since.
