The bilge pump quit working on my 94 Maristar, it will not work in the auto or manual mode. Any suggestions on what to check, the pump, switch, or fuse?

I would start with a volt meter on the wires at the pump to see if you have power.

But first check the breaker.

Ok thanks, is the breaker you are referring to located on the instrument/dash panel?

Yes.. Usually corrosion in connecting wires

First check to see if there is debris in it. That can sometimes cause them to not work at all also. I always try the easy things first.

Good call. It is amazing how much junk these pumps can eat, but there is a limit.

If you can separate the pump from a base plate try taking a peek in there first. Next meter with a volt meter as close to pump as possible. That should at least narrow you down to clog, pump failure, or electrical issue.

I tried to pull the fuse on the dashboard, and I can't get it to come out, any ideas on how to get it out to check it?

Not certain on a '94 but usually there is no fuse but rather a resettable breaker. Push the rubber nub. If you don't feel anything in there click then it wasn't tripped.

ok thanks, since I have no power even after resetting the breaker, would the pump or switch would be bad causing it to short out?

Grab a multimeter and check for power at the pump. If none work your way back from there.

My first guess is the pump went bad and tripped the breaker, a volt meter will tell you for sure. I replaced mine with an oversized pump as well, along with larger plumbing and bulkhead fitting.

If I was replacing mine I'd do this too. You can't have too much bilge pump flow if you get into a bad situation with a blown exhaust hose or something along those lines.

When mine failed, it was due to a corroded connection (pigtail coming from the pump). I'd look there first.
