1990 Ford Bronco, was running fine, parked it for about 6days went to start it and it wouldn't start. it is cranking good but no start. 14 volts at the battery. any suggestions? also I wasn't hearing the pump in the tank when key was turned to on position without cranking.

SOURCE: 1988 ford bronco 2 wont start but engine rotates

souds like you have no power to the coil when key is on

when you crank the motor you get a boost of 12v from the starter circut thats why it only runs when you hold the ket on start and stops when you ley it go

turn your ignition on and check with a test light if you have power if not check all fuses

you can jump a wire from the + side of the battery to the + side of the coil to keep it running to get you to a garage if you cant find the problem
good luck

SOURCE: 1987 ford bronco fuel issues

First thing to check out will be the fuel pump relay under the hood. It is the one who drives the pump, so if it is defective the pump will not work either to prime the engine, or to make it run. Secondly, you need to check if the fuel filters are OK cause sometimes they clog up and prevent enough fuel from reaching the engine. Thirdly, check the injector(s) for cloging, and clean or replace them as needed. If none of this helps, then the problem probably has nothing to do with fuel delivery, and the next step to check will be the whole ignition system, which is also one of the most comon bronco problems.

if it was me i would make sure its not the fuel pump relay give these websites a try www.alldatadiy.com and www.autozone.com if all fails stop by your local library and get your hands on a Haynes auto repair Manual for your SUV wish you the best of luck Michigan Man.

Here's the diagram for the fuse panel under the dash. There is also a fuse panel under the hood next to the air filter.

SOURCE: i have a 1990 ford

I have a 1990 5.8 liter ford bronco. When engine is cold it will start immediately. Once the engine is warm and driven a short distance. Engine will not restart until engine cools.
