Well I worked on tracing some more wires friday, and I traced them to the computer. I decided to pull the computer out, and just look at it. Before I even had it all the way out the smell of burnt electronics just about nocked me down. You can see where something on the board arched and...

My original problem is that the truck will not start it just turns over and over. I'm getting spark to the plugs. I'm not getting any power to the fuel pump or inertia switch. I haven't checked for any codes, because the bettery has been disconnected. Will the computer still throw a code...

well i went home and tried these things last night. It seems that I'm not getting a ground to the pcm relay, or the fuel pump relay. I can ground pin 2 on the fuel pump relay. The pump will then start pumping. Where does the pcm relay get its ground from? The computer?

I'm getting power to the fuel pump relay, but no power to the inertia switch. Help anyone

I have a 2000 ford ranger. I'm not getting any fuel pressure. I did the obvious things like check the fuse, check the fuel pump. The pump is not getting electric to it or something, because i took the pump out and hooked it to a 12 volt battery and it ran fine. When i put it back on the sending...
