SwissChris Posted March 11, 2020 Report Share Posted March 11, 2020 Hi, We had an issue wiring up the fuel pump tonight and at this point we think, that the ECU switched the full load instead of the relay. I understand that the diode is burned, which can be replaced but the question is if the CPU is still OK, or needs a replacement too. Cheers!
