The engine is turning but not starting. i replace the engine computer,coil,checked for power at dist,coil, and checked for fuel all was good, but the damn thing still won't start. PLEASE HELP

Did you pull a plug wire, short it & see if there's any spark..?

If you have a pickup in the distributor, that is the exact symptom of a bad pickup. However, you didn't say what engine and Ignition system you have. Is it a 302 or 351, EFI or Carb.?

There could be a number of things it could be. Start by checking the fuel pressure to the fuel rail with a fuel pressure tester to eliminate problems with the fuel pump. Check the computer for trouble codes that might send you in the right direction. You could have a bad fuel line or a bad fuel pressure regulator.

FUEL RELAY

sounds like your engine isnt getting enough fuel so check that entire system

I believe a distributor in a 91 Ford Bronco doesn't have points. I know the one in my 88 Doesn't, and it's a 302.

I'm stumped, I don't know what could cause the no-run problem. :wacko:

I had something similar happen. It was the fuel pump

i would have to say to check fuel preasure first, it sounds like a failing or failed pump....
