I have a problem and am at the end of my mind on the problem. I have replaced the fuel pump, filter, and control module and it still won't start. It will start on ether and thats it. So I know it has spark. Could there be something I am missing. I have checked the fuse and it is good. So where is my next step. Could the evac system be causing this. I just wish it would throw the check engine light and tell me whats wrong.

 

Is the pump running when you turn the key on?have you checked the inerta switch

 

Pasenger Side Kick Panel....remove the cover and look at the fuel pump shut off switch. Youll need a flash light.

 

Sorry, posted at the same time! lol

 

Yes I have reset the switch.

 

Are you getting fuel to the fuel rail? Is the pump even kicking in....check fuel pressure. How much gas is in the tank? Did the truck not start all at once? How old is the fuel filter....First things first though...determine if youre getting fuel.

 

I am going to rent a fuel pressure tester tonight. The pump is kicking on. I have had the tank out twice, it has about a quarter tank. But, when i turn the key on it shows no fuel. The truck started and died 2 seconds later. It does this occasionally now after the replacements. The fuel filter is brand new.

 

Have you checked your FPDM? (Fuel Pump Drive Module) that is located under the spare tire attached to the frame? If it is cracked or corroded it will cause a number of issues and not starting is one of those issues. Even though you are hearing the pump run doesn't necessarily mean that the drive module is working correctly. The new ones have been updated to where they are not mounted directly on the frame.
