Question

I tried 2 keys and have the same result. hard or not starting, like battery is dead or near dead. how do i narrow the casue between the IMMU and the ECM?

Answer 1

If the problem occurs try disconnecting the car battery for about 30 minutes and then try starting the engine with a known registered key. If the problem is still there the key will need to be reprogram, if the key wont program the IMMU will need to be replaced
