Ok I've been misled by my own doing. I first checked the MAP sensor and found a bad ground, so i fixed that, power tested good then retested ground and that was good. But never rechecked the signal wire. So I ordered the MAP and put it in, then tested the signal wire, which still has no signal. FYI signal wire is dark blue with dark green stripe. When I looked for that wire on the ecu I found two wires that look quite a bit alike. Tested the first one and nothing coming out. tested the second one which I am beigning to think is not the correct wire and that has ohm's coming out. I tested these with ignition off. So if the first wire tested is the MAP signal wire what do I check next???????????????????????????????????? Would that mean a possible wiring clip problem or do I need to replace the $850 ECU???? IDK................. Thanks, Josh

Bye the way I just wanted to thank BNTune for all your input, I'm checking all possibilities, now iI don't know where to start.
