Pathfinder 2002 crank but no start and no communication with ecu
I checked the 5v ref in tps it is there and the main relay is activated. Also, check engine is light when you turn on.
Any help???please
Have you tried another scan tool? Usually the cooling fans turn on with the key on if the ECM is offline. If the can high line is down sometimes you have to disconnect battery to even turn them off. If I get a chance tonight I'll try to look at a diagram.
