Question about 1992 Ford Bronco
Working on this for a month on and off. Ive had electrical problems everywhere but they are intermittent. Coil died first and replaced. Then the harness for the starter. Then fuel pump and pig tail. After that i replaced the cap and rotor, spark plugs and the fuel pressur regulator. Car cranks over fine and has good fuel pressure and spark. Ive read about pcms going bad but I would think I wouldn't have spark or fuel in that case. Could it be distributor is either junk or mistimed?
Are the injectors delivering fuel? just because u have fuel press it doesn't mean the injectors are working, buy a tool called a "noid", about $5.00, it plugs into the injector connector and blinks when u crank the engine if the injectors are working, u do one at a time. if not check the wiring harness to the engine, very common to have problems there. I have been a Ford dealer tech for 20 years and my specility is this type of problem, i.e. no starts, the ECM/PCM is not a common failure.
