Have you pulled out injector to see if petrol will come out?? Checked that the injectors are firing? I managed to put my fuel feed on the wrong way round on the fuel rail and meant that it wasn't getting any fuel

Hows the fuel pump? It needs to have enough pressure to crack the injectors open.
I have put the AFM on around the wrong way in the past, and that didn't help things go well either :oops:

start with the basic's first..have you got spark at the plugs ? use a timing light on each of the leads... its safer... if one or two dont flash the timing lite replace the spark plug lead..
are the plugs clean, not shitty from sitting around for awhile..
to check injectors its easy to hear them 'clicking' or using a small hose as a stesoscope.. as just getting the leads off can be a pain especaily #1 injector.
if the above dont work I have a lazy $100 :lol: :lol:
