ECM Relay Symptoms - No Start HELP PLESE
When I turn the key the instrument cluster and electrical systems work and I can hear air compressor on my allroad.
I turn the key to crank the engine and the whole car shuts off including the instrument cluster. No power what so ever
I am reading 2.8 volts on several terminals under the knee bolster after this happens. ~12V prior to starting. I need to let the car sit for a while before power is restored.
Could this be the ECM relay?
I called several dealers and they say many different answers. Any ideas?

ECM Relay Symptoms - No Start HELP PLESE - FIXED
Battery cable was not tightened down on terminal. This caused an arc when trying to start. Dumb mistake but very pleased this was the problem!! Thanks

Oldie but a goodie....similar thing happened to lady next door's chevy van.....new battery, didn't start it for a month or so...dead. Charged battery, tightened terminals...no problem!
