I have a 1996 f150 straight 6. I have replaced the rear fuel pump, pressure regulator, fuel filter, cam shaft position sensor, and both oxygen sensors. The truck still dies after running for awhile and will crank after sitting for about 30 minutes. It acts like you have turned the key off but will crank with no problems after sitting.

I have read that both fuel pumps should be replaced---why if only running on the rear tank?

Any and all help will be appreciated---at the end of my rope and pocket book!

I did take it to the dealership and they were the ones that told me the fuel pump, regualtor and filter was my problem. Charged me $82.00 to give me advice that did not fix the problem.

 

Did they check the fuel pressure? It sounds more like a bad ignition module.

 

Thanks for the reply. Did not check the pressure but pressure regulator was replaced. Not sure where the ignition module is located. According to Haynes it could be on the distributor or on the fire wall. It is an expensive part and I hate to replace it if it is not the problem. Autozone says they will test it if I take it off the truck and bring it to them.

Would the iginiton module cause it to die while driving? It cranks fine but dies after it gets hot and will crank again after it cools off.

 

Does anybody have any sugesstions on what to look at next? This is my daughter's only transportation and we need to get it fixed soon? I have taken it to several garages and since this is an intermittent problem with no codes they are just replacing parts. Getting too expensive and it is not trustworthy. Afraid to take it very far in fear that it will die and not start. It is also dangerous since it may die on the freeway and hard to steer when it does.

I know that someone else out there must have had the same problem.

Please help!!!

Thanks!!!
Please help

 

A faulty ignition module can cause the problems you are experiencing, although it is less common in the newer trucks because the TFI module is located on the drivers side fender. It's bolted to a heat sink on the fender, you should be able to find it easily. If you do replace it, make sure you put the heat sink grease on the back of the module so you don't burn the new one out. I'd definitely have it tested before replacing it.

 

Did you try the fuel pump relay.Before I got my broncoII,the guy I got it from had the same complaint and he replaced the relay and it was fine.Just a thought.Carl

 

I had sim. prob. with my 95 f350 460 engine ,cheap way is trying the coil wire ,the module is not that expensive but a auto part store should be able to test it,On my truck I ended up replacing the module the coil wire both fuel pumps distrubtor and it was the computer the whole time.I hope that is not your problem.mine would die driving down the road and restart anywhere from minutes to days.

 

Thanks for all the posts---I ended up taking it to the garage today. I will post again when I get it back. Hopefully to help someone else with the same problem before they have to spend too much money.

 

Problem was pick up coil and ignition module. Drove about 300 miles since repairs and runs great.

 

About how much did that repair run if you don't mind me asking?? I just had my distributor out yesterday and checked the ignition module and PIP sensor, which turned to be O.K.. Reinstalled dizzy and set timing last night. Found a plug wire off on number six in the process. A dizzy, reman, runs about $109 with the module on it , but no rotor and cap. Just trying to get some idea of what the going rate for a repair like that is nowadays??

Parts and labor was $313.00. I actually thought it would be more since the mechanic had to buy Ford parts. O'Reilly and Autozone parts were cheaper but they had to order and I did not want to wait so paid a little more for the parts from Ford .

 

Hey-
Thanks for the info. Hope you didn't mind me asking. This kind of info gives me justification with the "BOSS LADY" (WIFE) for all the tools I buy.

Thanks

No problem glad I could help. Truck still running good. Looks like the coil and the ignition module did the trick.
