HELP! 3 cylinders running on C20xe

[Robo]

I need help and bad nova needs a MOT so this morning taken her for a run fine temp's (oil, water) OK! Came back home time to fit my radio DONE! :thumb: BUT something is wrong and I don't know what...


Basiclly it's a (c20xe) running on 3 cylinders, change the plugs, leads, rotor arm and dizzy but still no change:confused: .. then ideas stuck! , crazy people around telling me to take covers off. The camshafts are OK only about 6000 miles since last rebuild, belt is OK too.. Was thinking it could be a block fuel injector anyone know how to remove, test,clean one,or has any one else had this problem.

Cheers

Have you done a compression test ?

[fearless]

Is the wiring loom for the injectors fully pushed down/connected ?

[Robo]

Planning for that tomorrow, forgot to say it's only cylinder 4 isn't running

[Robo]

not to sur but keep the idea's coming it all helps in the long run, I've been told you can feel the injectors working and when they are not, <<<<< THIS TRUE?

Put ht lead 3 onto cylinder four and see if it fires then.
