2004 Range Rover is not starting consistently. We've tried a few things to troubleshoot but aren't sure what to do next. If we pull Fuse 18 and put back, the car starts. If we pull the key out the car then does not start. The other thing we've done is in the steering column hot wire the blue wire to the ECU. The car starts. If the key is out the car for a little while (15-20 mins) the care does not start. Battery tested and charged. Alternator tested and good.
Thanks in advance,
Jeff

Sounds like we are looking at anti-theft immobilizer system issues. You may need diagnostic assistance on this.
