I do not have 12V at the Inertia switch (initial key on or when cranking). Thing i have tried - 12 volt control signal good at the fuel pump relay, main 12V pesent at the relay, swapped relays. I need a wiring diagram/schematic of the fuel pump relay/,innertia swtch and fuel pump driver module. I see that the wires from the inertia switch go to the power driver module but I don't understand the wiring. The Hayes manual shows the pump relay going directly to the inertia switch but it doesn't. Help anyone.

look at your relay closesly and possibly open it if it doesn't have a drawing of the internals to figure out which wire does what on the solenoid side. You should have power from the pcm power relay to power it and pcm ground to activate. On the contact side you would have power from fuse to supply the pump and then output to the inertia switch and on to fuel pump.Hope this helps
