Stranded at work!
After ~7,500 miles on the supercharged setup and ~12,500 miles overall since buying the FRC it finally left me stranded. Cranked over but no start. Of course I was at the top of the parking ramp at work…but Mark was able to give me a ride home to get the truck and trailer. I wasn’t sure if I’d be able to get the trailer all the way up there but it made it!
The new winch setup worked flawlessly and the car didn’t even bottom out on the trailer!
The problem ended up being a melted connector on the fuel pump harness. It seems the Walbro 450lph fuel pump was too much for the stock wiring and fuse. (18 gauge wire and 20 amp fuse). I fixed the harness and reused the wire as a trigger for a relay mounted by the fuel tank. The pump now runs on a 10 gauge hotwire.
I tested it once fixed and found it pulls 16amps constantly so honestly I’m surprised it lasted as long as it did. I’m pretty baffled that GM put a 20 amp fuse on a 18 gauge wire that was that long…but that problem should be solved for good now.
