[DML] Re: Fuel Pump Not Getting Voltage After RPM Relay Replaced



Oops, read Elvis' message before this one. Diagnosis procedure is
still valid for your NEXT problem (on a DeLorean, I've got to be kidding).

Vasoline isn't electrically conductive, is it? Be careful putting
things like ordinary grease on electrical connections -- as they melt
they can insulate them (see the other post about heat). Even dialectic
grease loses its electrical properties with time. Every owner of an
older car knows the experience of digging 30 year old dialectic grease
out of bulb sockets just to get the lights to work again.

I had a problem with that bundle of wires on the starter motor -- one
of the lugs accidentally touched the block, creating a dead short.
Killed my battery in 15 or 20 minutes. Note that if the short is bad
enough the errant connection won't even create a telltale arc. DMC
used that bolt as a junction point for all the hots. I made a short
pigtail and moved the junction to a midair space next to the starter
motor (only one cable now goes to the solenoid itself).
