Mudders
This thread will walk you through the procedure for removing, opening and cleaning the contacts on the Fuel Pump Relay on the 80 truck.
After reading thru RT issues in chasing down some hard starting, I decided that after 145k, it was time to clean the contacts on the Fuel Pump Relay, in an attempt to chase a slight miss on my 94. The result was better startup, and better acceleration. It's not dramatic, but certainly a worthwhile and *free* PM, assuming you don't break anything. If you do, I believe the relay runs about 80USD
LOCATION
The Fuel Pump Relay (FPR) is located on the driver side of the car, just forward of the fuel pump resistor. It's attached to the fender, and the body of the relay is inside the fender itself.
Here are the pics of the location. It is held onto the fender using a 12mm head self tapping screw.
Next up... Surgery.
