1991 2.9. Hello ranger friends. Hoping someone can help get rid of my insanity! Here’s what happened. Out driving one day and it started to either misfire or die out. It was hesitating badly. Jerking me in my seat. Made it home and tried to start it the next day. It struggled (fired here and there) but wouldn’t start. Couple days later, nothing. No spit. No sputter. Just cranks endlessly. Here’s what I’ve done. Verified fuel pressure at the rail at 40psi. Plugs are wet with gas when pulled and has a new pump/filter so I don’t think it’s fuel. Won’t even get a pop or attempt to go with ether in the intake. It’s got new wires, plugs, cap, coil, rotor, TFI and battery. Was running fine on all the new parts for quite a while. I tested for spark from the coil and got it. Same from the plugs. Seems good. Thought it might be timing so pulled the plugs, rotated the motor to TDC and made sure the rotor was pointing to cyl 1. I am going nuts trying to think of anything else! A friend mentioned it could be a temp sensor telling the computer it is too cold so then overfueling? I replaced both temp sensors at the top of the T stat.
