Have an ignition system concern and it would be helpful to have the schematic for the ignition system as i believ the gpr is wired into the injector pump.Thanks in advance for all your help to get this big dog barkin again.

 

The ignition terminal is wired in with the fuel shut off solenoid wire from the factory.

 

Thanks I just found the original thread,seems like the #1 fuse is directly affiliated with this system,is that correct?

 

Which #1 fuse:

cab fuse box is a/c- heater

Engine compartment: has letters for fuses

 

possibly pertaining to under hood fuse link.Apparently a yellow wire for ignition.Guy who I purshcased truck from told of how to provide for ignition system to function had pulled a few fuses under dash.Seems like a a possible short inline somewhere so the link you sent was very helpful and seeking the diagram for the gpr.Thanks again,Ron
