I have the truck listed above 1500. It is getting no power to the fuel pump. I've replaced the fuel pump, fuel filter, the throttle body. If I put gas in the throttle body it will fire right up. But shut off after it burns off the fuel. I don't know what else to do. Please help

Good afternoon,

Do you have a voltmeter to do some checks? I attached a wiring diagram for you to view and need to do some tests.

Okay, by the site rules, I can only address one issue at a time.

Please start a new question at the beginning and I will be glad to help.

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
