Hi guys, hope all is well. I'm new to the forum.
Please assist me if possible with the follow issue. I have an Astra H Z16XEP that cranks but doesn't start. It has spark, fuel coming through but injectors only spray once on initial crank and doesn't spray thereafter.

I have tried an Ecu, crank sensor, can sensor and injectors from another car.

I've tested for compression and it seems that it's abit low. It's around 100 psi, is this sufficient?
May be a little low, but I suppose that is with engine cold. That won't stop the injectors spraying though.

Thats way down though, should be about 14 bar = 200psi, i would recheck the cam timing, if its out then this will give you low compression and it wont fire the injectors.
