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



The things I pointed out to check are among the more common problem
areas. Obviously you have to get power to the fuse block and then on
to the relays. It does come from the battery to the starter and then
the alternator before it gets to the fuseblock. Unless someone had
touched the starter or alternator the connections on them are not
usually a problem. When they are a problem you should have noticed
that you had no power to anything, horn, lights, etc. That would have
been a tip-off that the problem was not "just" in the fuel pump
circuit but a more general problem. With the symptoms you described it
seemed to be "just" a fuel pump problem. I would inspect ALL of the
wiring connections now on the starter, alternator, frame grounds, and
bulkhead connectors. Make sure the wires are properly routed and are
not close to the exhaust manifold. The RPM relay you replaced was
probably OK. Keep it for a spare. You may want to try it to make sure.
