After checking fuel pump and replacing fuel pump relay I finaly got the car started but as soon as I try to give it some gas the car wants to stall out and butterflying it keeps it running but try to give it full gas it sputters and tries to die again. Any help is greatly appreciated as the wife and kids are getting sick of walking. Tyvm

Can you do a pressure test? Check for dirty MAF sensor and also check TPS. Here is the fuel pump relay location. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

After messing around for a month finaly got my buick running. Had to take to mechanic and it wasnt cheap. Now 1 week later it dies again figured fuel pump as couldnt hear it power up so replaced it and still nothing. What could cause a loss of power to fuel pump as I have a new fuel pump relay so I can count that out but not sure what else it could be. Any help is greatly appreciated as right now I dont have money to take to mechanic but have enuff for parts. Thanks a million in advance for the help the relay I replaced was under the hood in the relay center is there by chance a relay center that I am missing as some say there are some behind the glovebox. Is this so on my 99 lesabre?
Fixed the problem. It was a fuse behind the glovebox that was supposed to be 10 amp but had a 7.5 amp instead. Replaced and car fired right up.
Not sure who put wrong fuse in. But after driving the car a few miles with no problems all of a sudden it blew the fuse again and as soon as I turn key on after putting another fuse in it blows right away. The fuse I am blowing is for the ecm and maf sensor. This has me confused I know there is a short but not sure where to start looking to fix the problem. Any help will be greatly appreciated as I need the car for work
Disconnect all 3 loads and see if the fuse holds. If it does, then plug one in at a time and the fuse will blow when you plug in the failed part.If the fuse still blows with the loads disconnected, then you have a wiring issue.Roy
I found relays compartments under hood but noting display what these relays goes to how would I tell.
Hello, Here is the location of the fuel pump relay (below) with a guide to help test it.https://www.chrischona2015.org/articles/how-to-check-an-electrical-relay-and-wiring-control-circuitCheck out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.
Fuel pump stop working, I"ve sprayed starter fluid and it started right up but soon burned off when ran out. Want to check these before I buy a fuel pump.
There is no cut off switch. The relay is under the hood in the relay center. I would look harder at the pump. Common failure.Roy
Engine Performance problem1997 Buick Lesabre 6 cyl Automatic I am trying to find out where to locate the fuel relay pump for my 1997 Buick lasabre
Hello, it should be located in the underhood electrical center. Your owners manual, if you have one, should give the the location of fuses and relays.
Gas pump was replace but car still cut off. It will run good for 1 week may be 2 weeks. Then cut off like it was out of gas. The next day its good to agan. I was told that it was the gas pump relay I dont were it is.
Hello, there is probably a power distribution center under the hood, the relay may be there. I"d check the relay circuits when the problem occurs.One of my databases showed a fuel pump driver module, the other didn"t show that? I don"t know why there would be a module unless it was a two speed pump? I"m just thinking out loud.
My fuel pump runs all the time, just started a couple of days ago. Now tonight it ran the battery down. Could it be the relay or filter? It is a buick lesabre 97
That is an odd problem when key is off power is cut to pump fuse. Try removing pump fuse in instrument panel number 6 fuel pump. Let me know if is shuts off will have to find out how it is getting power. Any recent repairs?

You need to do some checks with a test light.Is power getting to the relayis the ECM grounding the relay when you turn on the key for a few seconds
