Answer 1
If it has good fuel pressure and assuming timing and compression are good then it would be spark related. -

My wife is having the same problem. once or twice a day the engine cranks, but it won't start. She lets it sit for 10 minutes and then it starts. Hot/cold doesn't seem to be releveant. Our mechanic claims he cannot solve the problem unless he is there with it when it happens. Right! He's come to her location twice; and each time, it started when he got there. He kept it for two days and it finally happened; but it started again before he could figure out the problem. He swears there's no diagnostic tool that can help. Hard to believe. Any suggestions?? -
