Hot Fuel Pump Relay
I was replacing a fuse in the front fusebox on my '86 930 today and I noticed that the fuel pump relay (the one closest to the cockpit) was pretty hot. I had just pulled into the garage after a drive that lasted about an hour. I haven't checked the fusebox before after running the car so I'm wondering if this is normal- or if I should be concerned. Other than the hot relay there aren't any issues with starting and the car runs great. If this isn't normal does it mean I've got a fuel pump that's ready to sh## the bed?

Shouldn't be hot, maybe slightly warm. Check all connections first. Makes sure everything is tight and clean. Bad connection=high resistance. High resistance=increased heat. Make sure all grounds are good and clean too. If all that is good then I would focus on a pump that may be pulling high current.

Check connections for carboning up.
I've had blown fuel pump fuses in the past and found carbon build-up on the connections (including the relays) on my 78 and 79. These were the old style pre-spade type fuses btw. I sand off the carbon from the brass connections. I then carefully and slightly bend back the tangs holding the fuses; and take a thin exacto blade to carefully and slightly open up the pins on the relays. This has gotten me home more than once. I haven't had to use my spares yet. You want to save those towing trips for a real break down.
cheers, mark |

Some one has said there is a chemical you can apply that helps too. Do a search, I forget what it's called.

Stabilant is good for maintaining conductivity. http://www.stabilant.com/

That's good stuff. But wasn't there a chemical that removes non conductive particles from conductive materials?
