2000 Pontiac Montana Fuel Pump

My wife's van is having a hard time with a fuel pump. Her gas gauge never worked since we bought it and then recently it wouldn't start. I bought a new fuel pump assembly from NAPA and we put that in. It fired right up and the new sender on the assembly fixed the gas gauge.

It worked for about a day, then it wouldn't start again. Thinking I shouldn't have been so stupid as long as I was under there, I replaced the filter and the relay to no avail. The person who was helping me thinks I just got a bad pump, but that seems odd. I went to NAPA and not AutoZone to avoid getting hokey electrical parts.

I'm going to exchange it tomorrow, but fear it's going to do the same thing. Does anyone have any thoughts as to why it burned through a new pump?

I should add that I didn't replace the wiring harness because the one on it looked fine. We tested it with a test light and it's getting power.

Its too bad that happened, but if you have tested the pump it must be defective. You can test the pump by powering it up with an external battery at the wire harness plug. Using a meter won't really help because the pump can be jammed with debris and won't turn but its still good and will pull current.
Check for debris before you take it back to Napa by the way...

if you look on the new pump it will say same as the old one made in mexico .they sell bad "new" fuelpumps everyday.they don't test each and every pump just so many out of a hundred or thousand. you didn't have to redo the harness connector? my new pump had a bigger connector so i had to cut the wires and heat shrink .

No debris. Made the Exchange at NAPA. Decided to amuse myself and quiz them as to whether they'd warranty the labor. What a joke. At any rate, it's a Carter fuel pump, made the switch and the van is running. Probably blew money on a filter and relay, but at least I know those are new now. I feel like getting out of the van and dancing a jig everytime it starts now. Needless to say, my level of confidence in the new one is not there.

Should have probably gotten a part like that from GM directly, but when both work, you need your car and scramble to get it repaired.....

the fuelpumps sold at gm dealers are made in mexico also so as long as you get oem pump you just as well off.as far as the van mine made me not ever want to own a gm product again.

The GM pump is made by Delphi and Delphi now makes Carquest's fuel pumps.Carquest was smart to do this and ditched Airtex whom was their supplier with nothing but failures.Carter and Airtex fuel pumps are junk.Napa's fuel pumps are made by Airtex

Wish I had known the carters where junk when the one on my dodge went, I had it out once and it worled so I thought my testing was bad as no matter what I did it would not run, once out no matter what I did it wouldn't not run so back in it went and was fine for 10 minutes before it quit. Replaced it with a carter which I thought was good, but about 3 or 4 months after warranty ran out it started acting up, turns out or best we could figure is the back flow valve in the pump was stuck open so when you shut it off all fuel flowed back to the tank. Ended up before I changed it again buying an 03 montana and I hope I don't ever have to change it. If I do I know what to look for now.
