Weird no start. . .
So a 2000 just quit the other day. Its been having a few goofy issues, not sure if they are related to the DPtuner or not, but I think not. Anyway, truck quit. #30 fuse is good. PCM relay is working. No fuel pump, no tach when cranking, oil pressure never comes up(guage) and no WTS light. My AE could not make a connection. The IDM relay #32 i think does not appear to be working. So thats where I'm at right now, havn't really dug into it too deep. Wanted some outside input.

Fuse 30 only supplies the power to the PCM and IDM relay COILS (and the fuel bowl heater).
Check pin "30" of the PCM relay. Is your Fuse 24 good? It supplies the PCM power for a 2000.

Well power for all those fuses are good. I have power to the 30 pin on the IDM and PCM relays in the junction box under the hood. I have no power to the #16 and #20 fuse under the dash. I am having a difficult time finding the fuel pump relay. Power comes out of the PCM relay and goes to the fuel pump relay, brake pressure switch, and through a splice goes to the pin 71 and 97(I think.) I pulled the PCM connector off and checked for power at those pins and it is there. I checked the ground and its good. With the PCM disconnected it acts the same. I'm thinking actually this PCM might be burned out. I mean. . . there is power to it. . . Can't think of anything else. Thoughts?

Do you have the additional three sheets of the Engine Controls wiring diagram?
If not, do you want them?
The above URL ends with 400. The additional sheets are the same except end in 402, 403, and 404.

yeah I have all the wiring diagrams thats to Mitchel, Thats how I traced all the wires to the PCM. . . like I said. . . two wires containing key on power to the PCM and both of them have power at the connector. Ground is good. Can't imagine the PCM is working!
