Hello I just swaped motors on my navigator and cannot start it. I believe it has something to do with the pats. It is a 8/99 5.4l changed with an 11/99 motor what esle do I need to change please any info would help
The PATS won't let it run at all, regardless if you pour the gas in. BTW, where, the throttle body? I'd look at the fuel flow. Get a pressure measurement at the fuel rail.
Perhaps in the meantime of swapping the motors, the fuel pump went bad. Check the fue; pump fuse. Check the fuel pump rely. Check the fuel pump inertia switch. If it runs
when you squirt fuel into it, it should run off the key.
