a mate has just been given a cfi ea. its a 30th anniversary series 2 with a 4spd auto.
first problem is the altenator and we cleaned it up and started it and it ran fine however the altenator wasnt charging much at idle (light flickering).
but it also stalls and then wont restart - it happened to him the day before he picked it up too, it wouldnt start, and the next day it was fine.
its a new battery and it cranks fine so its not that i'm pretty sure. the person he got the car from was given a spare distributor and told that was the source of the not starting/stalling problem. my question is how do we tell if its this? it looks like an absolute bitch of a job to change the dizzy on these.
also is there some way to do a diagnostic on the ECU with it not running? if someone could explain this and point me to a list of the error codes that'd be great.
btw when it ran, it ran fine and very smooth without missing or anything and then it just cut out completely. when cranking it doesnt fire at all, just cranks and cranks.
i'm used to VL commodores so it seems to me the equivelant of the crank angle sensor is whats gone, so the computer isnt triggering the injectors at all since it's lost its referance signal.
It's most likely the TFI module, very common problem especially with the CFI's for some strange reason, all you need to change is the plastic module on the side of the dizzy and not the whole dizzy itself, a new TFI module is around $90 from repco and have about a 3 year warranty on them. You'll more than likely have to take the dizzy out to change the module but it's not a real big drama being CFI.

also i should probably mention, i did the TFI diagnostic by unplugging the plug and putting the multimeter in the front of the plug (where the pins go). not sure if thats the right way to do it or not?
i think tomorrow we'll relocate the coil to the strut tower too. putting it on the side of the motor is stupid. is there anything you can get to on these things that is easy???!!?
