Hmmm... after leaving the ignition on overnight, I charged the battery up yesterday, and last night.

Connect it back up, and for a laugh, try to start it. You guessed it.... it goes. Took about 15-30 secs cranking.

So it seems I have an intermittent connection problem.

When I unplug the MAF sensor, nothing changes running wise. Does that mean it's borked? Does that have anything to do with starting?
