Problem With Fuel
So I Have a '13 f150 stx with the 5 liter in it and the truck wont start. The thing turns over for days but wont start which leads me to believe its a fuel issue, now I've already replaced the fuel pump control module fuse with a 30 amp and relocated it once before. The issue is that last time it was a quick fix, I bought the relocation kit and moved the fuse and rewired it. Last time it was easy to identify by the melted fuse in the fuse box, but now I'm at a loss because the new fuse is fine. How possible is it that because of the beefier fuse the power went through it without blowing the fuse but shorted out either the fuel pump control module or the fuel pump itself, and how do I test that.

When you turn the key to ON, and not START, the fuel pump should run for 3 seconds to build up pressure in the fuel rail... Listen to see if that happens... If it does NOT happen, then you need to measure the power and ground to the pump to see if there is POWER and the pump dont run, or NO POWER..

Older trucks use to have trouble with the FPM ( fuel pump module) that tells the fuel pump when to run... Have not heard of that problem on a 2013 , but if the pump will not run... something to check..

Try the number 8 Relay, if there is one in number 9 use it to see if the relay is bad, I think you can also use the relays out of 4 or 6 since they are not needed to make the truck run but check you manual first (one of those is the blower motor)
