I've had my car a 57 Vauxhall Vectra c 1.9 CDTI for 8 months, it's been the most reliable car I've owned despite not being the most expensive. I had the timing belt and water pump replaced yesterday in Manchester by a home mechanic, 30 miles from where I am. When he started the car after the work it ran fine no problem at his home for about 30 minutes while he left it idling to bleed the air out, then I drove home 30 miles without any problems. same night after it had been parked about 2 hours I went to start the engine but it just turned over, it sounded normal no unusual noises but wouldn't start. Today I disconnected the battery, went to start the engine and it made a noise like clatter or something, I immediately took key out and have not started it since. Somebody said they'll have a look tomorrow, though this person's reliability to arrive is in question. he says he'll try turning the crank, if it turns with his hand everything is fine, is that correct ? what do you think the problem may be, if ti was a timing problem would it not have displayed symptoms right away ? thanks
