I have a 88 Ford Bronco that stalls unexpectedly and on different conditions. I've taken the truck in many times and no one can figure out what is wrong with it. (when the tech has the truck it runs fine). The fuel pumps have been checked and they are all fine. The truck had a tune up and it ran fine for 2 weeks and then stalled and would not start untill the next day. It ran fine for 3 weeks after that and then stalled again while I was on the road (almost got hit). Does anyone have any ideas on what could be causing the problem????

 

When it stalls does it seem to run out of gas? Or, does it just shut off? If it seems to run out of gas I suggest replacing the fuel filter if you havent already. If it's just shutting off it could be your ign. module. Here in CA they recalled them due to this problem.

 

Thanks for the reply.

It sputters and then stops. The tech checked the filters and he said they were fine. Was the recall covered by Ford and how long ago was it? Is there something I can refer to when I talk to Ford?

 

Ok then the recalled Ign. modules wouldnt apply to your situation. sounds to me like a fuel delivery problem. In that case it could be anything from your fuel regulator to the high/low fuel pumps.

I do know the pump in the tank rellies on the fuel to cool itself but if it sucked up something in the sock or quits intermintently it could cause this problem.

 

i'll say it again check the small wire or wires on the negative cable.they will cause the same problem.i went thru alot of parts before i found this little problem
