went to start my car yesterday, fired right up then proceeded to die. i immediatly noticed that my SAFC/RSM were not working. checked the ECU fuse under the hood and it was blown. got a replacment and replaced. car still won't start, SAFC and RSM still dead. so i do some detective work with my multimeter and find out that on the ECU side of the harness, that i get continuity if i attach the power (pin 49 IIRC, same that SAFC and RSM get power from, as well as the ECU) to a ground. so my ecu is grounding out there..but how? if i disconnect the ECU from the harness its not grounded out anymore. is my ECU dead/fried?
