Ranger wont start

[scrapper]

I'm busy right now but I did take the icm off and got it tested at autozone, he ran it a few times and it read good every test. I think maybe it was not getting a very good ground. It was corroded really bad and the bolts were really bad also. I did snatch one off of a 94 ranger but it isnt a ford, don't know what brand, just in case. I'm going to check the tank and go from there. I bet it is a wiring problem. I hope not but I will start checking to see if something isnt getting a signal. Thanks for the help so far.

The ground wire on the crank sensor was not working so I cut it off and put a crimped connector on and it got a ohm reading on the ground from a couple of different spots. It still wont start though even with starter fluid.



Well I hooked up my code reader and got 2 codes pcm fault , I think it was 513, and 543 secondary fuel system fail.Unless there is anything else to check I'm going to get a new computer. I'm not sure about the secondary fuel failure code.Any ideas out there?

Okay I replaced the computer, fuel pump relay and the coolant temp sensor. I didnt check the codes again to tired. I checked the coils and swapped them around. Did not make any difference. I did spray carb cleaner in the intake and it would barely run for a second or two. It didnt have any fuel pressure when I turned the key on or when I cranked it.It is not getting fuel so I'm starting to track that down. I am probably going to have to drop the tank, so I can check the wiring. I can see it, can feel it, just cant get it unplugged. I checked the fuel cutoff switch and it was ok. I'm guessing the wiring is the next thing to check then put 12 volts to the pump.Anything else I might be missing?
