Firstly, anyone got a wiring diagram?

secondly, anyone ANY idea why I cant get a spark, IF..

I'm getting .07 AC volts signal from the CPS when cranking
EDIS has power/switches injectors/fuel pump/has continuity from CPS wires
Coilpack has 12v at the plug

but still no spark?

I've extended some wires, BUT I done each wire one by one so as not to mix any up...I cant see any other reason why I cant get a spark though other than somehow ive messed the wires up, pretty certain they are all correct tho?

This might be so far off the mark mate but i had a problem like this and it was the ground strap/wire to the block wasnt any good and there wasnt a good enough earth to let the plugs spark.dont know if that would cause your problem just an idea.

I did actually think of that, i've got 2 earths that I think are pretty good though, i'll maybe stick another on just to be sure.

cheers.

Cant you ask Alan

studabear

is the coil pack any good?

JesseT

Most common mistake is to wire the CPS polarity wrong.

T28, Yea Davie Alan's been giving me a hand and without a wiring diagram to go through it all were stumped, which is why im worried LOL

Stu, coilpack is fine, it all worked when I took it off my fiesta 3 months ago!

Jesse, What do you mean wire the polarity wrongly? i.e. wires round the wrong way? at which end?

Anyone else got any idea's?

Anyone know what the AC voltage from the CPS should be? I'm getting .7 volts.

hi mate not clued up alot on electric but is it an ac voltage form the cps ? will it not be a pulse in dc ?

have you checked to c if the injecters are pulsing

vroooom ptssssh

Gup, yea mate injectors are going...

KArlos, As far as i'm aware the CPS gives off an AC current, just like an ABS sensor.

when cranking fella check the back of the coil plug wiring with a probe and c if your getting a live and switched earth on the outer oins as it maybe the edis senser gone down

I've tried an 'unknown' edis and still the same,

The middle pin is constant 12v feed, and the outer ones im pretty sure are doin what they should be, It's weird...almost like something isn't earthed? tried an extra earth on the head and no joy...

Does the edis need to be earthed to the chassis?

one my one when it had a misfire on 2 and 3 fella the outer oin on the coil pack was switching live to earth,but on the other side it was a constant live and when i done my furthr checks it ended up being the edis module,i got another obe fitted it and it sorted it out
