Factory service manual info offer - 87-89 Pathy
Tommy88PF replied to 88pathoffroad's topic in 86.5-89 WD21 Pathfinders
Hello, Do you have a pinout diagram for an 88 WD21 VG30i ECU. It is a MECS-G400 23710-33G00. I have been trying to repair a faulty injector in my throttle body. Both injectors have been cleaned and tested but when put I them in place one freezes open and dumps fuel placing my ECU in failsafe mode. I have unplugged each injector to find which injector is bad and done the 9-volt battery test (both tests which I should have done before anything else) and can hear the faulty one and good one as well clicking so I believe there is a wiring problem as the ECU states(I also should have paid attention to the ECU code stating circuit problem instead of injector problem. Just hard headed I guess.) I have been unable to find any diagrams showing the layout of the pins on the ECU so I can test the continuity of the wires from the ECU to the injectors. Thanks for your help. -
