You cant go wrong with a synthetic oil. A bit more money but worth it.

If it has fuel, air and spark, it only needs one more thing to fire,...compression. If it has those four things, in the correct ratio, it MUST fire. If you are 100% sure on the fuel, air and spark issue, start looking at the timing. I would also have the codes read off the ECU. Could you have " thrown " the timing belt?

you dont need a diagram to see the timing marks on the top/bottom pulleys,just clean them off and run a piece of chalk around the perimeter.they are a bit obvious.....

The egr valve may be faulty or leaking air. Otherwise you may have a plugged or cracked vacuum line or low vacuum pressure

No. I would go with the cheaper set.

have you looked at the engine earth/ground cable, run another earth from the negative terminal to the body(wheel arch) and then to the engine block and try again. As you would know its a proccess of illimination and this was the most simple thing that came to mind. Let me know how it goes.
