JB hi fi fitted my new stereo about 8 months ago.
Have a new issue now - for the last couple of weeks about once a week the paj wont start, not even a click.
Thought it was the new immobiliser (fitted at the same time as stereo), spent a couple of hours checking battery, starter, fuses found nothing, got battery load tested - excellent.
Car starts when battery reconnected, figure this reset problem with immobiliser. took it down to JB's, they couldn't find anything, got them to bridge out fuel and ignition cut to prove it wasn't the problem.
That was last week, this morning wifey drives kids to school, gets back to car, won't start.

She disconnected the battery, reconected - starts
Thinking i may have a computer problem?
