I just bought a theft recovery 1990 chevy s-10 blazer.
I have no power to the fuel pump. Were the electricity goes after the fuel pump relay is a mystery! Just wondering if anybody here knows common spots the wire breaks or good test points to find it. I really do not feel like striping the interior to trace a wire.

Thanks

I know that a common point on the fullsize trucks is right where the wiring harness transitions from the firewall to the frame rail. Might want to check there.

Or you could just run yourself a new wire from the relay to the pump.

 

In my 93 2 door jimmy the was inside and ran out, thanks to manitobas "imoblizer" stopped my truck from running so i had to re wire my fuel pump.. worked better after but i know i had to change a relay to get it to start working? a toggle and some speaker wire never hurt no one though :P

 

The orange wire is the power and the gray wires is to the Fuel pump on the relay

 

I live in manitoba to and that immobilzer put my 93 gmc jimmy 2 door to its rest, wouldnt turn it on, so i did the exact samething i just rewired it to a toggle to, it was alot easier then i though too. Tested it on a battery to make sure it was good cause i had just put it in about a month or 2 before it stopped working
