    Hey. So there is a bit of a battery drain somewhere in the car. I dont know where. Would love some ideas where to start checking.

    Also its strange because the car won't start on a jump. I'll connect a good red top optima to the strut ground and positive post in the engine bay and the starter solenoid will click over a bunch of times but it won't send 12v to the start to get it started. I've even gone as far as to jump the 12v signal wire from the solenoid to the starter and it WILL catch and start but soon after sputter and die (immobilizer)

    BUT if I put that same red top in the trunk it will start up and run fine. . . Super strange. I'm wondering if the immobilizer needs some kind of constant 12v from the rear of the car in order to work. i can't for the life of me figure out why it won't take a jump. its so weird.

    any thoughts on this?
