    Jase, see here Revo stage 2 yesterday and cambelt gone today

    So Ash, who changed the belt for you? Did they not think to see if the old one was ok and tackle the starting/spluttering problem first?

    Fuse 10 is the fuse for the management is it?

    When you checked for fuel, may i ask how you did this?

    Did you remove the fuel rail and see if the indavidual injetcors were spraying?

    right, so fuel seems ok however the fuse blowing would indicate some kind of fault. The coil wiring is a common short, i would try the injectors plugged in to make sure they are firing. If they are it's most likely the crank sensor failing and send incorrectly timed signals for the spark/spray in my experience so far

    Assuming all was well with the physical timing. It's not turning over too fast by any chance is it? I have had a bottom pulley key shear, that put the physical timing out, but the belt looked intact still, and it still sparked and sprayed as it should
