>Yeah but the fact that injectors 1 and 3 have no life then it sounds like an electronic problem rather than an issue with the distributor/leads/plugs.

but seperate problems surely? Ign coil is firing so he should get 4 x Sparks, but if the injectors aren't running either:  (1) broken injectors, (2) bad wiring or (3) transistor drivers faulty on ECU

You only ever need two tools in life. If it moves and it shouldn't use Duct Tape. If it does not move and it should, use WD40.

The more I read the more I think you have a ecu problem  :undecided:
Quite likely that will be the solution, but why isn't the getting a spark for all plugs past the dizzy?  Thats got to be dizzy, lead or plug related.

I think they are 2 faults as such, injector problem cannot really be much more than the ecu as that is all that really controls them.

or bad wiring, or bad injectors or bad sensor(s) (crank/cam).  Makes sense to prove these before condemming the ECU I'd of thought.

At the end of the day - it just does what it knows howto based on its inputs.

Javalin/james> well ive changed the crank sensor already, and if it was the crank sensor surely it wouldnt get a spark at all? or does it use seperate notches on the crankshaft/ flywheel to tell what the position of the piston is in each cylinder? ive tried with the dizzy unplugged but i only checked the spark not the injectors,il do that on saturday. it has no mass air flow sensor, only air temperature and intake manifold pressure sensor, but il try unplugging them.
is there a micro relay for each injector within the injector rail or is that all in the ecu? yeah its multipoint.
il try checking 2 and 4 leads again

il try what youve suggested sensor wise, if all fails i think its going to have to be a different ecu.

does anyone know how to recode an ecu with vcds/vagcom?

I THINK it hasn't got immob. Reason I say it is because it's pre 95 ECU, AE and BE were used after that. Someone will confirm though  :smiley:
