Have you interrogated the codes? What do they come up with? I think jumping to just changing parts is a good way of getting things wrong!

I would go for some sort of help from the recovery services to give their opinion. It could be the battery, starter motor or fuel pump possibly; obviously you should test these first with the aid of workshop manual. What did the plugs look like by the way?

The egg smell is coming from the catalytic convertor not burning all the sulphur in the fuel and it is being released as Hydrogen sulphide (stink bomb material).There is a fair chance the cat has packed in or the sensor.This link explains it better than me.

Having slept on it the camshaft sensor could be worth a try its quite a common fault on these engines.
