Have you tried starting then quickkly whip a plug out and see if it smells of fuel?

I know you have no spark, but on the EFi system the two could be linked....

The ECU gets an engine running signal from the coil firing, if it doesnt get that it won' t add fuel,....if the plug smells of fuel, then the system thinks the coil is firing and as such engine is runnng.....if there is not smell of fuel, then the ignition circuit LT needs looking at....

Have you checked the ignition amp as these are a common cause of issue.
 
The plugs are damp and stink of petrol. I have fresh fuel in.

I'm beginning to suspect the dizzy or a replacement part is faulty. Perhaps the pick-up? The ignition amp was the first part replaced. Is there an ohms test for the amplifier?

I got no spark at all.

I tries sticking a plug in the lead and then earthing it on threads. I then ran a jump wire from the negative terminal and the plug would not spark.

The only spare coil I have is a "09-220 12v BAllasted coil"

Would this work on the EFI?

No.
 
Found out when efying a mates car. Thought it was timing 180deg out but it was ballasted coil. IIRC they put out 6v at idle rising to 12v with revs
 
Cool, thanks for that. I checked the timing twice and the best I got was a cough. Like I said, I'm suspecting one of the replacement parts as faulty. Any other tips would be good.
 
Okay, in the meantime I did a few more tests from the manual.

Before removing the dizzy I ran a test between bat positive and negative on the coil...shows 12v manual says it should be ..er.. zero.

Removes dizzy and did pickup test and seems fine there.

I don't know if this means anything, but I probed both amplifier (old one and new one) on the bench and it's as follows

Old one:
input:16.9k Ohms
output: 82k
New one:
Input: 7.18 milli ohms
output: 15.8k

Does this mean anything?
