Hello I a m trying to locate the fuel pump relay to check and see if it is bad or check the fuel cut off switch fuel pump not delivering fuel to the motor want to check these parts before ording a fuel pump. Where can I locate them on a 1997 Buick Lesabre. Put starter fluid in the intake and it starts right up, soon stops once it burns off, can you give any advice thanks

There is no fuel cut off switch on a 2006 Chevy Malibu. You either have a bad fuel pump, a bad fuel pump relay, or no signal tuning on the pump relay if you have a no run condition of the pump.

You don't give a year or model so I will cover both ,carburetor model no cut off switch, mechanical pump sucks fuel from the tank and delivers under pressure controlled by the float needle and seat to the carburetor . fuel injection no mechanical cut off switch pump is powered from the ignition switch via a relay, the ECU will switch off the fuel pump when the required pressure is reached .

Bad fuel pump will not cause it not to crank, but can cause it not to start. Test with fuel pressure gauge. If it will not crank, entirely different issue=bad solenoid/starter, bad battery connections, bad ignition switch, relay,wiring.

Hello abzalkhan193
Heres a few things to check that could cut power to the fuel pump. The fuel pump inertia shutoff sw
in the trunk on the left side, there is a reset button on the switch if you push the button down and
you hear/feel a click then the switch was tripped and you just reset it. The switch's job is to cut off
the fuel in case of an accident. Next, the fuel pump fuse located in the battery fuse block under the
hood on the right fender well, fuse #1 20amp fuse. Next, the fuel pump relay, the relay is located in
relay center on the left fender well. Hope this is helpful.

there is no fuel pump cut off switch . put a fuel pressure gauge on the fuel rail schrader valve turn key on you should have 40+ pounds of pressure if you dont the pump is not working open the relay center under the hood swap the fuel pump relay with the wiper relay and try again if no pressure its not the relay its the fuel pump if you do have fuel pressure that means the relay was bad get a new one the car should start if you do have pressure and the car wont start the injector circuit is dead and what causes this is the crank sensor located on top of transmission bellhousing on driver side auto parts store 38.00 dealer 170.00 when you change it make sure to push it in and hold it while you tighten the bolt hope this helps and please dont forget to rate my solution

I don't remember this vehicle having a cutoff switch. In that year most manufacturers that were installing cut off buttons were mounting them in or just behind the glove compartment. If the pump has stopped working check the fuses located inside and under the hood of the vehicle and check the fuel pump relay. If all are good it is most likely a bad fuel pump you will need to replace.

ok your cut off switch is under the glove box in the passenger footwell in the UK version, and mine did not have any further relay until the wiring hit the fuel pump itself, i had been told it was behind a panel in the back under the rear passenger windows, but having removed the entire inner trim of the rear of the car could find no relay at all. my problem was not relay in the end but a dead fuel pumpconfirmed by checking that i9 was getting voltage delivered to the pins of the pump plug when ket switch in position 2 as that is when the pump primes the engine

its under the hood on driver side what the problem not starting check the trunk area for the fuel cut off switch poss bad or tripped did u get hit or someone bump ur car

won't claim as a solution but...

Have you verified that fuel is pupming (is the fuel pump working?)

there is a pressure regulator on the end of the fuel rail that is vaccuum activated.... is thier vaccuum getting to it to create pressure for the injectors..

Just s few items to check....

Check the fuel pump cut off switch located behind the carpet on the passenger side up unde the heater box, pull the carpet back and see if the button on top of the switch is pressed down, if not there behind the panel passenger footwell right side same thing also make sure the switch has power coming in and going out. BUT! you gotta be quick the fuel pump relay controls this power and only suppllies power for 2-3 seconds then it turns off. so plan ahead get your test equipment all set-up and surn the ignition on if you have power great turn off the key and move test stuff to tho other wire on the fuel shut off switch get ready and turn on the key power good no power bad fuel pump switch but No power to the switch likely a bad ffuel pump relay.
