Hi there.. I have just replaced the fuel pump on my astra.. 2002 reg. It has the Y17DT engine in it.. I did the timing but i seem to have it wrong.. What i did was got 3 bots and stuck one in the fuel pump and the otheres where they are ment to go.. But i have knoticed that you can tilt the pump towards the engine or away from the engine how to you know where to put it as i know its in the wrong place.. from the way its running.. I hope someone understands what i am trying to ask.. I spoke to vauxhall and they said you need a special tool to sort it out.. is this true or just a way of them making more money.. I hope someone on here could help me out or give me a answer to what i have done wrong or how to over come the problem..
