About the wire harnes: someone pull that already, maybe that truck was in a shop or something before.... Ok letme ask you guys this: If the crank shaft is disconected, theres no signal to the ECU and for that reason theres no spark right? Ok But the fuel pump need to build pressure no matter what right? Or the ecu is cutting the fuel power too bcz the crank shaft sensor is been disconected? Now, in the case of having the crank shaft plug in but the spacers in the wrong positions, should I have power on the pump at least for 30 seconds? Bcz im not even getting 30 seconds from the fuel pump........ Today I will work on her, so let's see what the deal is.....Thanks Guy's!!!!!!!

It is in the underhood fuse box. Drawing sent earlier in post. Ignition key turns it and other things on. Main relay powers up sensors, etc. It also enables the starter relay and the fuel pump relay, but those are switched on by the BCU or the ECU, which ground them to operate. You'll need the RAVE, it is possible to do this on line by exchanging messages, but it is like playing chess by mail... takes a while. Relay info attached.
