Hello group. I am a new member here with a problem regarding no juice going into the fuel pumps on my F-250 5.8 4x4. I was hoping someone could assist me in figuring out what could be wrong.

There is no electrical power reaching either of the two internal fuel pumps which are in the gas tank.

We replaced the fuel pump relay, and the 20 amp fuse.

The inertia switch was not tripped and is in the normal operating position.

When we parked this truck one year ago, it ran good. It still turns over good but it will not start. I replaced the distributor and rotor. I also used a spark plug tester and it is getting a spark when we crank it over.

We bought a fuel pump but did not want to install it until we fixed the electrical problem. Today, I took off the utility bed and, whenever we find the fuel pump problem, we'll take off both tanks, clean them, install pumps and fuel filter, and end up putting on a regular truck bed.

Also, there is no power to the inertia switch.

We don't know much about electronics on vehicles so any ideas to our problems would be greatly appreciated. Thanks.

 

Are you getting a check engine light or any codes?

 

Yes, the check engine light comes on, but I have no knowledge of codes or anything to detect them.
