No power to fuel pump
Your problem is most likey the corrosion at the connector under the car. Try temporarily bypassing the fuel pump circuit on the connector by running a jumper wire around the connector tap into the gray wire on both sides of the connector.
The ground for the fuel pump also goes through this connector, this is the black wire. It needs to have a good connection as well. If you are unable to clean up these connections and make them work, then the connector will need to be replaced. You will have to pull back the carpet and drill out the rivets to replace the connector.
What is that connector called? Do you have a part number?
Thanks...lol I already depinned the plug and harness. And hard wired them into the same lines as before. Nobody knew what I was talking about even after seeing the part and pictures.
I got the part from AutoZone took forever to get them to understand it but it AC Delco pt1123 is the part number probably that when you ask him
I have a Buick rendezvous 2002 I have power to my fuel pump but fuel pump won't work
A very common problem is that the Buick Fuel pump fails...…replacing the fuel filter every 30,000 miles to help prevent undue strain on the fuel pump
David.....try holding the key in the on position for 8-10 seconds......that electrifies the pump and sends fuel up the line......may work, unless it is already a total fail. What were you experiencing before this happened? Was it hard to start? You should have had signs that it was going to fail beforehand.... like taking 2 to 3 times to crank to get ignition??
because the PT 1123 is most likely corroded there's a pretty good chance that all three connectors that connect into that connector are corroded as well so there are several things that go into that whole connector as a whole your two speed sensors on your back wheels clip in there is the fuel pump or sending unit connect into that Part also your evap vent solenoid connection to the same pigtail that your fuel pump does it's amongst the wires that are in that harness that clips into it so if you start having gas cap issues wait until you replace the PT 11 23 before you do anything else because if wire's are shorting out because there is no connection because of the corrosion it could be causing pretty much all your problems also if you look up PT1123 on Amazon it is the correct part it may say it's not compatible with your Buick rendezvous but it is the correct part if you go further down it'll tell you the other two clips that clip into it it's probably advisable to pick those two clips up as well because the two clips have the rubber seal on them so when they clip into PT 1123 they sealI was also reading on a Buick forum that those pigtails that come out of the PT 1123 should be checked every 20000 miles for correct ceiling and make sure that there is no leak by of water into the connector compartment if so they need to be replaced again otherwise you'll be replacing that device again
