86 2.9 liter won't restart after engine warms up

[jeremybme]

So my ranger will start and you can shut it off and restart. No problem. However if it runs for 20 min or longer and gets nice and warm and you shut it off then it will not restart until it cools down hours later.

When it won't start. It does crank and there is spark but there is no fuel pressure at the fuel pump.

Any ideas or help would be appreciated I don't know what to do and really can't afford to just start tossing money at it.

Thanks
Jeremy

Hmm sounds like a faulty TFI module. They often go bad and will cause the engine to stall or not run when warm.
When you say you dont have fuel pressure at the fuel pump, do you mean no pressure to the engine(i.e. fuel rail)? After the engine is warm, turn the key on and listen for the whine of the fuel pump priming the engine. If you dont hear it it might be the fuel pump relay. If you do, try getting a fuel pressure tester and testing key on engine off pressures both cold and when hot. I dont have the specs around me but I believe its like 32-40psi or somewhere in that range and I think it drops a bit when running.
