Actually I have a bit of a dilemma. I changed the water pump and the timing belt and the engine ran. Should mention here that I did it using the cambelt locking pins. Sadly the gasket on the water pump leaked, guess I wasn't careful enough when I installed it. To cut a long story short I set the engine with the timing marks, locked the camshafts again, then removed the timing belt AGAIN, removed the pump, reassembled the rubber gasket adding a splodge of Hylomar Gasket sealant, refitted the pump and belt .................. I haven't done anything different to the first time BUT the engine won't fire up, she just spins on the starter motor. No nasty noises coming from the engine, she just refuses to start. Suggestions, bearing in mind the engine ran first time and I used the same timing marks second time round Is the position of fuel pump critical ???................... I didn't think it was being a CRD Chris
