Hi, I have my father truck that will not start I have no gas presuure at the fule rail. I was hope some one here could send me the wiring diagrams. and yes I checked the fiuse. thank you

check the fuse box under the hood... for a fuel pump relay.. just an idea.

 

assuming its a triton the last stop for 12V before the pump is the inertia switch. Turn the key on and if you have 12V at both of the larger gauge wires at the inertia switch then everything else is good.

 

Yup, this right here.

Fuel pumps aren't uncommon things to fail on these trucks. Which year is it? How many miles?

 

Hi thank you guys for the info it's a 99 with 200k on it I looked up the wiring diagram it looks like the fuel pump relay is providing the 12volts and the ground is being switch from a wire with a resistor at low speed to a direct ground for hi speed. I pick up a new relay for $12 will be back at it at the end of the week.
Thanks again
