igniton woes - no spark

[Justin..]

getting fuel, injectors are firing, but no spark. ECU problem ? its only thing that seems to be left. i have tried a different working coilpack.

[MAXIBOY]

is the coil pack being triggered...maybe ecu dizzy cap rotor arm tdc sensor..

how have you tested for spark....could be faulty earths also...

[Justin..]

tested for spark with a spark plug in the king lead and a HT lead and earthing while turning over


TDC ? wheres that

[MAXIBOY]

the one on the gearbox thats triggers from the flywheel...

how did you earth..

[Justin..]

earth to a few places. the liftin eye on the engine, the bonnet catch, any where there was bare metal realy where the cable reached



is tdc also known s crank sensor?

Think so. It's the little black plastic thing on the top of the gearbox I think...

[Matty86]

crank sensor must be fine surely? it's firing the injectors

[philthy]

sounds like ignition drivers on the ECU

[Coops]

i'd guess the chip mate, its recently come to my attention that the chips require a base board aswell to run, andy fielder has more info from when he tried to copy my chip, give him a pm and have a chat as i dont fully understand what is going on, but he had a look at my ecu at fcs and seemed to think he knew why

[Justin..]

hmm thats not good to hear coops. i shall pm.


Ecu was at fault. my mistake as to injectors firing, it was just the 5th injector, which flooded my inlet


managed to get it running today with a williams ECU. (cheers Summeh)
