About a month ago my 89 302 bronco suddenly started running like you know what studdering stalling and looked like the engine wanted to jump out of the truck. I found that I was getting 0 fuel pressure but, all relays were working, good spark, and I could feel the pump on the rail working however not the one in the tank. I went ahead and replaced the pump in the tank (after 300k km it needed it), blew out the fuel lines, and cleaned the reservoir, still no start. I am getting some fuel pressure but it's not shooting out of the valve like you think it would I will need to borrow my brothers gauge to check it. I can't pull codes because the bulb is either burnt out or removed. I'm starting to think that my injectors are not firing cause I can't feel or hear them working I'll have to test them tomorrow. Could it be the pcm, tfi module, map sensor, a weak frame rail pump, a long list of other sensors, etc? I want to take it out wheeling and thats only making me more mad. I have checked the grounds and they seem good to me, I'm real lost on this one I don't know much on the efi system these trucks have I'm more up to speed on the carbed Windsor's. Any help is appreciated I don't want to be throwing money out the window and replacing parts till I find the issues.

 

Any input? I'm not even sure I posted this in the right category.
