Hi,
I had the joints resoldered, and replaced the fuel pump relay, that worked for some time but now after 2 weeks I wanted to start her up and it is back to no cranking again.
I checked the relays, they all click on 12v applied.
So I put key to the right, dash comes on, then turn all the way right to start and nothing, not even a click, yes the fan starts spinning.
I tried to measure voltage to the pump relay that is on the most left connector, but got nothing.
Traction relay comes on clicking, but engine relay I think not. Fuses seem fine. Relay measures some 60-75 ohms.
Any chance the problem lies before the RCM? Some wire issue? Or would this also fit the security block issue.
