I have a 1998 jeep cherokee,,, i lost fire so i put a new coil, then a new PCM on it,and fixed the problem... Then the oil light came on,,,i put a new sending unit on it, NO GOOD,, i had to have the PCM flashed at the chrysler place, and they said oil sending unit was bad,, so i put another unit on the truck but the light is still on[[[[ i put a external guage on it and i got 40 lbs oil pressure at idle and 70 driving..I tried to see if it was a bad ground on the plug, put a wire to it down to the frame and the light goes off for 2 sec. then comes right back on,, BUT if i take that same wire and run it through a mutimeter to the frame the light goes of and stays off,,, WHAT THE @#$$%% PLZ HELP

no you need to see if any of the wires have continuity with the frame...like you have a wire somewhere that is grounding out or broken.
