no spark

[360bhp-rs-turbo]

Hi I just fitted new engine to my esc cos and now has no spark. If you put a plug in one of the leads you get a small spark when you turn on and off the ignition but nothing while cranking. Any ideas what is causing this fault. could wrong gapped cps do this. fuel pump isn't priming as well

Fuel pump check

1fuel shut off (passenger foot well)
2 fuel pump relay in fuse box under drivers side (fuse No9)
3 check CPS gap and make sure all pegs are on pulley
4 check temp sensor plug, rear of engine block passenger side.




HTH

done all of the above an still no spark but what I have found is when I unplug the blue sensor on passage side of block the pump will prime but as soon as I plug it back in it stops. running out of idea's now

But for me no fuel pump priming
The fuel pump wiring disconnected but there was always spark there

Yes bud. what im finding very strange is the fact when the coolant sensor is plugged in the fuel pump wont prime but as soon as I unplug it then it prime. now have a spark but a very weak one

Is the rear engine earth connected as this sounds like an earthing problem.

As above I would check your earth. I have also heard that the ignition amps can play up as well.
