1990 bronco fuel pump runs for several minutes then my truck will start will not start till the pump quits it does this when its cold when its hot it starts fine i've changed the fuel filter the pump seems to be fine cause its running I took the line off at the engine and there seems to be plenty of pressure. Could this be my regulator?Or a sensor?Or something else any help would be much appreciated

I have the same exact problem with my 1990 ford bronco. It seems to be related to humidity, cause that is when it acts up the most for me. Tell me if you have been able to fix the problem

I have a 1994 bronco it dont have problems starting but when it is hot out it has no power and dont really want to go but when it is colder out it runs pretty good but not as good as when I got it a year ago. I have changed the o2 sensor in the muffler plugs wires distributor fuel filter air filter and no difference if anybody has any suggestions let me know
