Chevy does not use a fuel cutoff inertia switch.
Mounted on top and inside the fuel tank.
GM vehicles do not have a fuel cut off switch.
Yes. It should be in the fuse/relay center under the hood.
switch it with a relay that works, like your horn relay or simulate the relay with fused jumper with 12 volts from your battery. 87 on your relay is your out to the fuel pump. putting 12 volts to the point of contact where 87 would be should start your fuel pump.
No there is not, Need to check the fuel pump relay and the fuse.
fuse box underhood driver side relay no. 41
A Chevy Avalanche uses standard 87 octane fuel. Higher grade fuel will not result in improve mileage or performance.
It does not have a fuel cutoff switch, you have to remove the fuel pump relay to disable the fuel pump.
To change the fuel filter in 2002 Chevy Avalanche, first locate it beneath the driver's seat, then engage the emergency breaks, loosen up the gas up, and replace the filter.
I have not started yet but I know you atleast have to drop the tank. I'd get yourself a Chilton.
The fuel tank capacity of a 2003 Chevy Avalanche is around 31 gallons.
