Thousand and five Envoy shut off fuel switch - 2005 GMC Envoy

battery has a full charge and battery connections all good? There is no fuel shut-off. engine cranking, you have spark at the plugs and fuel injector pulse? At the fuel pump, gray wire is voltage, black wire is ground. Engine cranking, if you have good voltage and ground at the fuel pump but no fuel pump action, suspect the fuel pump.

There is no reset button on envoys ! Ford has this inertia fuel shut off switch, not GMC or any GM or Chrysler ,dodge , jeep ! Some asian vehicles have it .

Bad crank sensor usually is the cause. Or fuel delivery

Check your fuel relay.

fuel injectors operate on a pulse from the computor. remove the fuel rail and insect the suspect injector 2 things will cause the injector to dump fuel.ethier the injctor has come apart at the end or the ijector is stuck open.hope that helps. you might be able to turn key on with
fuel and elect connentions to see which one is leaking

look at main fuse under hood if it pops it will shut the hole car down check the battey or hook a battery charger on it 2 to 4 amps then see what u get

The evaporator for the air conditioning is under the dash on the passenger side. Open the hood and look on the firewall for a rubber hose that sticks out of the firewall. This hose is to allow the water to run outside and onto the ground. Sometimes they plug up and the water can't get out so it builds up and drains onto the floorboard. Hope this helps...

Heres your answer, I also have a envoy and it did the same thing. Have you catalitic converter checked, your exhaust is all plugged up.

check fuel cut-off switch, shut fuel down on in impact.think its located in trunk, check owners manual. ;hope this helps.

i have a 2005 ford 500 and my fuel reset switch is on the passanger side under the glove box to the right. it is labaled. hope this helps
