hi guy any ideas the sparks intermittant and i get no injector pulse on efi rs turbo only if i turn it over for a long time i get a slight pulse ,i have thought coil pack but would this stop the injectors any help would be much appreciated

 

Check and make sure the trigger wheel CPS is clean/gapped ok and indeed works ok, does fuel pump prime when problems occur?

yes mate fuel is there as when i was messing with it i broke the regulator and didnt notice til i was turning it over and petrol was running every were lol thanks for you suggestions i will check them out

 

yea as said check the CPS, its the same as a 2i pretty much bar not having a turbo and the CPS's get gunked up easily!!

 

also check the speed senser plug(gearbox one) as this can cause you the same sympton

dose the cps have to be a certain gap from the fly as it run till i had the face of the fly skimmed due to the paddle eating away at it

 

will check all sensor's round the box cheers lads

 

It can be out and still work obviously a slight tolerance, ideally of course you would have it right, more importantly is the teeth and that it can referance these ok, now we know it was working fine until the flywheel was refaced. Did the flywheel go back in exactly the same position as it came out? if not this will be your problem it needs to be as otherwise it will be out of time with rest of engine and hence CPS will not be reading correct.

I think the flywheel bolts are staggered so it will only bolt up in one place. Even if it were in the wrong place - it would still spark and fire the injectors but the timing would be wrong and the car wouldn't run.

Did you accidentally clout the sensor when you took the flywheel off? Might be worth trying a different one. It's less likely to be a speed sensor as this is primarily used by the ECU to sense overrun, and wouldn't stop the car from starting.

 

Tryed a new cps and ecu think it mite be the wiring to the cps as the plug has been damaged at some point and been replaced will have a look over it weekend cheers paul

 

Could certainly be, don't know on your car but on Cosworth's the car loom side of the connector loses grip on the pins hence bad connection.

The two pin CPS plugs are prone to heat damage from the turbo on CVHs, - the plug gets cooked and brittle then breaks. This is worse on cars running a T3 as the plug is even closer the the turbo than on a T2 powered fiesta.
