Hot fuel pump relay
After the motor is running for awhile, I can shut it down an try to restart. At this time it won't start, it will just spin over. I pulled the fuel pump relay and it is hot. I put in a new relay and it cranked right up. Is this a sign that I need to replace the fuel pump?

Trace the fp wire and pull it free of the fuse block (not difficult). Either bend back the clip-part of the connector to make a better connection and add a little dielectric grease (worked for me). Or, snip off the old connector and crimp in a new one.

Most likely you have a poor connection at the fuse block that is arching causing the relay to heat up.

Just went through this mess. My fuse block section was burned so bad it melted the plastic on one terminal. It got to the point where the car would only run about minute before the relay would overheat and cut out. Replaced the fuse block and installed the Racetronix fuel harness to eliminate the relay overload from my BAP. Runs like a scalded dog once again.
