Ive ran the bronco for nearly a year with no problems, a few days ago I was driving home and the engine began to sputter like it was low on fuel, I nused it along and made it home sputtering. I parked it overnight and tried to start it the next morning with no luck, it turns over but will not fire. The fuel pum, p is only 6 months old as are the fuel lines, and I can smell fuel when it turns over, I have not yet checked for spark or compression but what do you think the problem is? And what do I do to get her running again?

If you can smell gas, then you probably have lost spark.

Take your ignition control module to a parts store and have them test it.

Did u get it started?
If I can help I have a 91 with the 302 and it kinda did the same thing. Ive replaced the o2 sensor plugs wires distributor rotor and idle air control sensor. The plugs were fouled from a rich mixture so I tried the o2 plus etc fired right up idled poorly and kept stallin. Just changed the idle air conntrol sensor and idled good took it out ran a hell of a lot better. Check engine light came on got it home idled terrible again. I was told it might be the throttle positioning sensor or drive idle sensor. Im no!Mechanic so im just advice if you could help me out with any info id b appreciated

I would start with the crank and cam sensors. Check the connection at the crank.

It only brings up a code when maf is unplugged and I cannot get a reading because the truck will not run with the maf sensor plugged in

There are key on engine off codes as well with the fords.

I assume it is a new mass air flow?

My truck starts occasionally. It will crank but not turn over the other times. I have replaced: battery, spark plugs, plug wires, dist. Cap/rotor, starter, starter relay, fuel pump relay, powertrain control system relay, negative battery cable, coil pack, and the ignition starter switch. I think it might be electrical because when I leave the key on the on position and wiggle wires under the hood I hear the fuel pump relay reset and thats when it starts. But sometimes it will stop running while I'm driving. Somebody told me it could be the fuse/relay box under the hood could be corroded. Also could you tell me what those 4 relays under the hood next to the fuse box? I cant find what they control anywhere.
