Car only runs with CPS unplugged ?

[Seany boy]

Hey guys , long story short....

 

Iv got a 55 plate DE zed, after a rebuild I ran I to electrical problems and the car wouldn't spark and the injectors wouldn't open...

 

After a lot of testing / checking / changing parts she runs but only if the Crank Position Sensor is unplugged...

With it plugged in the car cranks strong but won't muster fuel or a spark

 

Any ideas where I should be looking next ?

Already fitted

 

New crank sensor

New LH cam sensor

New RH cam sensor

Ecu

Wiring harness

 

Ecu is coded as is the key (light goes off the dash etc)

 

Also had alsorts of code readers on it and they all say it's clear , to check I unplug a sensor and it brings the fault up

hi, well as you say it will only run with the CPS disconnected this leads me saying the flywheel is bolted on in the wrong postion;

 

The cars ECU works out that the CPS signal isn't in the correct position or the signal isn't the correct waveform it will then read the cam signal and run the car on the cam signal, this will also stop the variable cam control not to work this can be also looked at with a good code reader.

 

any questions ask away.

 

thanks
