I have a 2000 VW Jetta 1.8T that is having an intermittent ignition problem. The problem first occurred just over one month ago and has been happening with increasing frequency since then. Basically, the problem is that at certain times when I try to start the car, it will turn over but not actually start up.

The battery is fairly new and all of the electrical systems seem to function normally, even when this problem is occurring. When it does start, it runs fine and never stalls or dies, acceleration is smooth and so is the idle. There has been no discernible pattern to trigger the problem, it has occurred in both wet/dry weather, hot/cold temps. day and night. The only consistency is that it always seems to happen when I am on a deadline or have to be somewhere work related.

I suspect the problem could stem from either an electrical failure (i.e. no spark in the engine) or a fuel system failure (maybe fuel relay pump?). If anyone has had a similar experience and could share any info it would be greatly appreciated. I have taken it to Pep Boys, the VW Service center and a private mechanic and not one of them has been able to diagnose the problem. Please help!! =(
