update

I'm about to call a local breakers and obtain a PCM cheap to try out, we will update with 165/185 and then test the car. This morning it did not start after starting yesterday after battery charge, it was left overnight this time with alarm on but no voltage drop today. Alarm guy who fitted my Clifford 5.1 says any drain is less than a clock so highly unlikely alarm. If can rule out PCM then may have to look at Starter and Alternator replacement. Battery confirmed as correct one one.
