How do you turn on fuel cutoff car hasnt run for a while put new battery in

If I read your post correctly, you car cranks but does not start. If so, could be a PATS problem. Try starting the car with your backup key.

If it hasn't run in a couple years, I would use a "test light" and check for power at the plug-in for the fuel pump. If ther's no power I would run a wire from the battery straight to the fuel pump itself. If the pump doesn't turn on you will have to replace the pump. If this starts it. If this makes it work you could put a fuse in the wire and hook it under the hood to any wire that has power when you turn on the key.

If you are trying to get it running again after 2 years it might be a good idea to pick up a Haynes manual for the car. They're only about $20 and have a lot of useful help for the DIYer doing average repairs. Hope this helps.

have a mechanic scan for computer codes this will put you in a better direction than just changing parts although it wont tell you the exact problem

The gasoline in it is very likely no longer any good. Put new gas in with an additive designed to remove water and it should turn over.

There are fuses for the fuel pump and should be located under the hood.You should not run the pump out of the fuel tank the fuel keeps the pump cool and it only takes about 15 seconds to destroy a new pump when running it out of the tank.Chances are you might have ruined the pump by running it out of the tank.

Start with the fuel cutoff......sometimes they need to be reset. Step 2 would be the the fuel relay.........I doubt that the fuel pump is not working as you said you can hear it engage. Let me know if you need anymore help.

i'm guessing that your fuel pump is not working.

If you're car has been running fine, then suddenly won't start, the cause is frequently that the fuel pump cutoff has been tripped. Open your trunk, and look for a label for a fuel pump cutoff switch. Locate the switch, press it in, and see if the engine will start.

Try changing fuel filter

There is a fuel pump cutoff under the glove box on the exterior side, make sure it is not tripped and the fuel is being pumped. Two things you must have for a combustion engine is fire and fuel. I just installed a new V10 myself in my excursion and it runs great.
