Occasionally my MSP will not crank over the first couple tries, it has been doing it for a few months but it always starts the 2nd or 3rd attempt. Well two days ago when I put the key in I got nothing like the battery was dead, the alarm started tripping over the low voltage and jumping didn't help get it started. It did however start on it's own after a couple minutes when the lights came on and it cranked like normal.
My first guess is the ignition switch or relay, second would be the alarm module. Haven't had any problems with this car in a long time, I suppose it's due.
