I know. it was just a ritual that seemed to work
I changed the batteries in the keys just a few weeks ago, so I don’t think that is the problem. The keys seem to communicate with the keyless entry to unlock the doors and the start button. I’ve also tried it with the key in the ignition the old fashioned way.
I just don’t know enough about the system to debug it. But “lock-wait are few minutes-unlock-go” seemed to work in the past.
It was starting to occur almost every day before I had the engine pulled last Nov. We did find a mess of burned/dried out insulation in the wiring harness under the oil filter that connects to the Bank 2 coil packs. My mechanic cut and re-soldered all the connections added additional heat insulation - plus I installed the intake spacers which seemed to keep the engine bay a little cooler. After that, life was good with no codes, no burning oil, and no ignition problems… until just recently.
This past Tuesday the same thing happened when my wife drove to work and parked outside (temp in the upper-30s) for a few hours. I came by, locked it according to the ritual above, went inside to the ATM to get some cash, and it started just fine when I returned. Then today, we stopped for 30 mins at the vet, and then when we got back to the car… nothing.
The only other thing I noticed was that the lights don’t flash when I locked the car anymore. The lights do flash when I unlock it. My mechanic thinks this may have something to do with the front passenger door lock that I replaced with a Euro salvage model. Maybe the computer is NOT getting a correct signal from this door lock - hence the immobilizer?
I’ve left the car at the vets this weekend and am at wits end. Worse, I tried to start it enough times that the battery is now weak.
…any more ideas?
