The Range Rover won't start. Relay 16 (Starter Motor Relay) gets no ground signal from the BeCM; thus the engine does not crank. Jumping those terminals spins the engine over, but does not start the engine, even with the ignition on. Traced the ground that should be appearing on the relay when the key is turned to start, and it goes to a white / red wire into the yellow plug on the front of the BeCM. There is continuity, so no break. BeCM was replaced in the year 2000. Alarm seems to work fine; locks / unlocks as usual. When attempting to start, all the warning lights come on as usual, ABS pump, etc. Fuel pump runs momentarily and then shuts off unless I jump that relay where it runs continuously. It gets the ground signal, as do the rest of the relays. Nothing else is different with the vehicle, every single other function works fine--no sign of impending BeCM failure at all. I have tried everything and need help. First--why won't the car start when the ignition is on and the starter relay terminals are jumped (car cranks over?) Is the car immobilized somehow? On the BeCM it is the yellow plug (larger one I think) terminal #2 white / red striped wire which should be sending the ground signal. Its not. What is the condition which causes the BeCM to send that ground signal? Ignition switch prob? Ignition switch operates everything else fine. The BeCM clicks when you turn the key to start. Car has 139k on it runs great. Just drove it somewhere and then home, ran fine, then it wouldn't start. Died across the street and had to use the RR Classic to drag it home in transfer neutral.
Any ideas? ETM BeCM chart?
