2003 Ford F-250 5.4L Gas - I pulled over to get a coke at a store. I’d been driving for 40 miles. When I came out the engine wouldn’t start. I had it towed home. I put the fuel pressure gauge on it and turn the key to start but the gauge registered zero. Didn’t move. It had done this a few times before but started after a rest.

Is my fuel pump bad? What about this Fuel pump emergency shut off sensor? Where is it?

I have heard the fuel pump relay is soldered. The relay is not serviceable since it is built onto the circuit board of the fuse junction box under left side of dash.

 

What YEAR, MODEL, and ENGINE?

 

I'm assuming 2003 Ford F250 from his past posts, but no where can I find a spec for the engine. Maybe he'll come back with more info.

 

Sorry 2003 F250 5.4L

this guy wrote about the fuse box with integrated relay.

 

Bump

Well, the fuel pump isn't working but there's about a dozen things that can cause that. What, specifically, have you checked (other than youtube)?

 

Like maybe a bad fuel pump? That’s what it was. Nite

 

Glad you got er fixed!
