Answer 1

Need more info. Why did you change all of that stuff ? and what made you think it was a FUEL problem to start with. I need to know.

Have you checked the wiring connector where it plugs into the top of the tank with a test light to make sure that you have power at that point. Chevy had a problem with that connector shorting out causing the fuel pump not to work. Check it.. Do you KNOW if you have fire at the end of the plug wire where it snaps onto the spark plug when you are cranking the engine over ? Need to know.

Sometimes when you install a new fuel pump and you KNOW eveything else is working right. But it still won't start then try this. Turn key on. Do not try to start. wait 4 seconds then turn key off, wait about 1 minute and turn key on again for 4 more seconds. Repeat these steps about 4 times and then turn key off and wait a minute. Now try to start the truck. If it won't start, Then I REALLY need to know the above answers. Thank you.
