    ECU Pins

    in 86.5-89 WD21 Pathfinders

    Posted

    Ok thanks for the tips. I'll clean it up and hopefully it won't corrode again. Yea it was the only pin that was corroded. I thought that was strange too. I'm still trying to solve a no start. Battery, alternator, starter are new and tested when bought. Spark plugs, wires, cap, rotor and ignition coil are all new. I rewired all the corroded connectors I could find, which was quite a few. The truck turns over but won't start. When I pull the ignition cable off the distributor and ground it to the frame I get no spark when I try to start the truck. I get the correct resistance on the primary ignition circuit but no reading on the secondary. I'm thinking that the ignition coil I bought might be a dud or the ICM died.

    I found this while digging through my harness for any bad connections. It's the largest connector on the ECU. The one pin on the bottom row, third from the left is corroded. The clip inside the harness connector going to it is also corroded. I looked in the Haynes and on here and couldn't find a diagram to identify which pin this is. The wire for it is black with a blue stripe. Does anyone know what this is for and what would be the best way to change out the pin and the clip inside the harness connector?.nu7aga5u.jpg

    After repairing the alternator harness connector the truck still will not start. I measured (per Haynes) the resistance in the primary ignition circuit and it was within spec. When I measured the resistance on the secondary circuit it wouldn't give a reading. The Haynes says the the secondary circuit consists of cap, rotor, spark plugs and wires, the ignition lead from the coil to the distributor and the secondary windings of the ignition coil. The cap, rotor, plugs and wires, and coil are all new. I'm stumped where to look next. Is the "secondary windings of the ignition coil" the book mentions, the ICM that is bracketed with the coil?

    It was plugged in when I found it. The pic doesn't show it too well but the connections and corroded and I don't think I can reconnect it without it crumbling apart. Do you know what connector that is? One end runs by itself past the radiator and connects to the harness on the passenger side fender. The other end is bundled with the two that are still connected and they go along the driver side of the block.

    I replaced both temperature sensors and the connectors for each. I ran the codes again and nothing came up, all clear. Truck still wouldn't start. New cap, rotor and plugs and still no start. How can I test to see if the ignition coil is good?

    My pathy would not start the other day. It turns over and partially combusts but it won't start. I ran the codes and code 13 ( engine temperature sensor ) was the only code that showed up. I replaced the sensor and the connector to it and it made no difference. The battery and starter are only a couple days old and both were tested at purchase. I have a 90 amp maxima alternator that's only 3 months old and it was tested at purchase too. I checked all the fuses and fusible links are they are fine too. I'm not sure where to go from here.
