Anybody familiar with Ford Broncos (fullsize) and the 4.9 straight six in general?

My deadbeat uncle left his Bronco at my grandparents house, the guy is in prison and my grandparents are tired of having this thing up on blocks in front of their house, so they want to sell it, the problem is that it stopped running, and my uncle never fixed it.

I got it back on the ground and after messing with it for a while I still couldn’t get it going. I sprayed some starter fluid in the intake and it wanted to start, so I started checking the fuel system, I couldn’t find a pressure port on the rail or the line, so I really couldn’t verify rail pressure. I checked and the fuel pump relay was all broken, the fuel pump fuse was blown, I replaced those and still nothing. I listened to the tank and I can’t hear the fuel pump, I just hear a click when you turn the key on, we cranked it and still no fuel pump noise.
Do you guys know where the pressure port on the fuel supply line might be? I’m going again and I’ll be checking for voltage on the wires going to the pump.


anything else?


I have a video of it trying to start up that I will upload and post here in a second

cool thanks man

I will try that out, BUT if I remember right, the relays/fusebox look different on this bronco.

Im going to try the inertia switch to see if that works
