92 bronco will not start
Ok, fuel pump runs with key off, truck will not start, cannot pull codes now, waited a week and it started again but only ran for 10 minutes then when I tried to rev the motor it began to backfire and wanted to die. It will idle but it will hesitate. Is this a fuel pump or is my ecc going out? Need some help!

Fuel pump relay is latched (stuck on) if it runs with the key "off". That's the first issue. Any symptoms prior to it behaving this way? Backfiring is indicative of timing issues which could be attributed to PIP sensor failure or TFI module failure. Neither are cheap so it might be worth while to run the KOEO even if all you get is stored Codes. Memory Codes will at least let you know if there had been some issue prior to the no-start condition.
