ECM controlled relay
Anyone know what conditions would prevent the ECM from energizing the ECM relay, the relay supplies the injectors I can only get my engine to fire if I ground the relay coil as the ECM would, car has been sat for over a year doing a resurrection and working my way through the faults, car has new water pump, hoses, belts, plugs and coil packs fitted recently.
cheers |

pin 18 missing ground output for ECM relay https://cimg3.ibsrv.net/gimg/www.jag...12f2289531.jpg I was hoping it had been pushed in but its gone |
I soldered a wire to the circuit board and connected it to the wire in the harness through a in line fuse lets see if that works
|
Works great! still chipping away at the faults, now I need a TCC solenoid and a harness with the temp sensor for the 4L80E transmission faults anyone know if the standard GM parts will work in the Jaguar spec trans?

All of that green in the black connector is copper corrosion.
You should give some thought to cleaning it out. |
Moff,
If you hadn't figured it out by now, the GM parts for the 4L80E will work in the Jag version. It wouldn't hurt to go ahead and replace the A and B solenoids while you're down there too. That's some scary ECU fouling! It's a known problem area. Did you discover the location of the leak? |

I don't think I have a leak my guess copper sulfate build up might be due to the electrical connection (electron flow) and the damp air in the foot well causing a chemical reaction similar to the build up on some battery terminals, just a theory |
Air that damp probably came from a fouled or broken drain line!

Or a humid Virginia summer! |
