Guest mozart Posted June 2, 2005 Report Posted June 2, 2005 Can anyone help with the pin details for the Motronic 3.8.1 ECU, please. My intermittent fault has finally become continuous and the most obvious problem is that the ecu is refusing to ground the fuel-pump relay, so I need to find out what is upsetting it. Cheers. :( Quote
Guest mozart Posted June 23, 2005 Report Posted June 23, 2005 Next Question : I've managed to figure out that the crank-angle sensor and several other sensors are not earthed. I found an earth connection on a bracket on top of the engine and although it just looked a bit grubby, it turned out that the wires had corroded slightly where they were crimped inside the ring-connector and there was no continuity. So, I've replaced the connector-rings, but none of these is for the CAS. I've also replaced all the connector-rings at the bulkhead earth-point behind the coolant reservoir; still no joy. Does anyone know where the CAS etc. are earthed or have I got a break in the wiring harness ? Any help much appreciated, I'll post my progress. Quote
