Good day,, I hope someone can help, I had my head gasket redone, now my car don't want to start, ECU is speaking to all the modules and working, cam and crank sensor working, Can timing seems to be correct, but as per outo electrical, the pulse to the injectors is at the wrong time, can anyone tell me what I can do to fix this problem.
Thanks very much Pieter Van Eeden

Are you 100% sure the timing belt is fitted ok? Did you use locking pins to hold the cam and crank in place?

Yes, locking pins were used, Is it possible that the cam can be 180 degrees out, and is it possible that valves could be bent, as we did descover that the belt was 2 teeth out.

The cam can't be 180° out if locked in the correct place, but it can't be 2 teeth out either, if the correct procedure is followed. The engine is an interference engine, so any deviation of more an a few degrees can cause the pistons to contact the valves, which will result in them bending.
I fail to see how the timing belt can be 2 teeth out, if locking pins are used, it's impossible.

Can you hear that the engine has compression?

If the pulse to injectors is out, that is timed by crank position sensor.
Would that not mean the crank is 180 deg out?
Was the crank moved with head off?

Thanks, I removed the tapet cover today, to do a leak test, it seems that the vales is fine except for one exhaust valve, I do not want to remove the cams, as I am not sure how to put the cam Cain back on.
