Right, fitted brand new battery, still no crank. Checked all battery cable connections. Removed RCM and checked all PCB tracks, components, continuity checked all pins to board, and tested all relays with good quality Fluke DVM. Re-fitted RCM with cover and switched ignition on, fuel pump relay operates and then releases after a few seconds (correct) and ECM relay operates and stays operated (correct). I'm confident RCM is good.
Now, pulse module, I see from starter wiring diagram, the circuit from key goes through the PM before reaching starter solenoid, anyone know what the PM does ? How to check ?
Am going to jack car up and check starter and solenoid.
