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.
