Ford 5.0 fuel injection problem........
A few years back I upgraded my 78 CJ5 to a '90 5.0 Ford engine. I physically installed the engine and the "dummy" parts of the harness. My brother stepped in and cleaned up meshing the two harnesses together. It's been awesome......up till now.
I've basically upgraded the jeep beyond my knowledge.
Now it seems like the jeep runs great 90% of the time, but after it's been running for quite some time it just doesn't have the RPMs to keep moving. Some days it's a short distance, other days I've driven it without issue.
I suspect a fuel delivery problem. But due to a weird combination of parts (explorer plenum and f150 fuel rails) I am unable to get a fuel pressure gauge on the fuel rail's nipple.
The fuel pump is relatively new. I know that doesn't mean a lot. But I put the pump into the jeep, then I've hardly driven it. Probably less than a 1000 miles in the last year and a half.
So basically there are two questions. Is there a way to diagnosis this problem without having the gauge? Or does anybody know if there are fittings that I can screw onto the fuel rail nipple (like a 90 degree elbow) that'll allow me to put a gauge on it?
