xj not running properly

[waynehartwig]

today i got the temp gauge working but broke the sensor so that will need to be replaced eventually, for now gravity is holding it in place. i switched the oil pressure sensor but now i don't get any reading. i got some intermittent readings so i probably just didn't make a good connection when i spliced in the connector.

i also tested the cps but there weren't any markings on the terminals so i don't know what the readings mean. i found a better how-to guide online than my repair manual so i will use that tomorow to see if the cps is the problem.

I'm not sure on the 91, but the oil pressure sensor might be a switch. Just like an idiot light. The ECM takes the signal and displays a abitrary pressure on the gauge, regardless of signal - unless it's lost, then it shows 0.

Point being you may have it hooked up wrong, or the wrong guage or?
