Compression test the engine. You have spark and fuel.

rayccfc

done that all cylinders read the same

Swap plug leads 2 & 3 see if the problem moves to cylinder 2. Could be a knackered coil pack.

rayccfc

thanks for the reply i have done that

rayccfc

is this the problem when i start it up number 3 does fire a little bit for about 30 seconds then stops when i take the plug out its wet but the other thing is when it is running on the other 1 2 4 cylinders and i take the lead off with the spark plug in the head nothing happens and when you take the injector clip off aswell still nothing happens so in other words why does the spark and injector stop working at the same time
cheers

Piston Broke

Maybe worth just scoping the loom mate if that's ok I would get the PCB checked see if there's any cracks under heat etc. When did it start or was it out the blue or after a hot run etc

cheers
