No power and lots of back firing!

[Rmachines]

hi, my 2E GTI has no power what so ever!  my 1.4 pulls harder!   Also if im in over run i get allot of pops and backfiring!  but the engine ticks over and runs nicly.  I cant get my head arround it!

What should i be looking at?   Fueling,  timing, etc..?   Nothing has been changed since it was last working as far as i know,  other than being sat for a few months!   i just changed the gearbox 

Cheers

Did you damage the crank sensor wiring?

umm,  possibly!  I will have a look where it is on auto data and take a look, Cheers.

Ok from what i can see all the wiring is ok!
