Hi everyone. I have a bit of a problem. I have a 2000 F150, 4.6L Triton, with 202k miles. On the way to work, it just quit!!! Odometer read nothing but dashes. I pulled over and tried to start it. No start!!! The engine turned over quickly (good battery power), but no start. Got it towed home and tried to connect my OBD2 tool to it. After numerous tries, it won't connect!!! I checked all of the fuses in the cab and under the hood, all are good. When I try to start it, the fuel pump does not prime, you can't hear it. Thoughts??? Suggestions??? All appreciated!!! Thanks...

Fuel pump might be bad?
Have you checked the fuel cutoff switch? The inertia switch?

No, no, and no. You must consider the symptoms in their entirety to come to a reasonable idea of what might have failed. Failure of the fuel pump to operate is a secondary effect/symptom.

Go read the thread, in its entirety, that Dee Veloper linked to so you understand what is happening. Given your stated symptoms, I'd suspect that your PCM lost its power. Could be a loose/blown fuse or the PCM Power Relay (most common) has failed. If you want a quick shortcut, go swap that relay with another identical one that is not critical to engine operation. Mark them first
