Hello everyone wasnt sure if this would be the right section to post this so apologies. Ok so th eother day my 08' f150 would crank but not turn on. I checked power it was good. I replaced the fuel pump driver module and still would not turn on. I sprayed some starter fluid into the throttle body and it turned on. It was good for a couple days then it didnt it again, crank but no start. I came p with an idea and decided to push the truck to a level ground cause where I park it has a slight incline. Truck tuned on with no problem. Please any input would be greatly appreciated. Can it be the fuel pump or fuel related? Please any input thank you in advance.

 

I would say it's fuel related since it started right up when you sprayed in starter fluid.

 

Thank you JCR56.

 

Fuel related since you moved it from an incline to a level surface and it started. Fuel as in not enough in the tank.......lol

 

If you run tank with a low level of fuel its hard on fuel pump the gas cools the fuel pump motor ,plus you also have a lot of air in the tank that can condense water into the tank .

 

Thanks to all for the responses gonna have the fuel pump looked at

 

You don't just look at a fuel pump... any codes ? CEL

 

That’s the weird part No error codes no check engine light on.

 

Have you changed your fuel filter?

 

No have not changed the fuel filter yet. I should try that also right?
