I've been having troubles with my 88 XR2.

Doesn't seem to be getting a spark at all.

It's getting power and an earth to the coil.
2 powers and an earth to the ignition module on the distributor
All engine earths are good

So far I've.....
Swapped the coil
swapped the main ignition lead to the coil
checked that the rotor arm is ok and turning


Only thing I can think of is the module on the distributor being faulty (i'm not even sure how this works or what it does exactly though).
Or maybe the dizzy itself?!
(anyone got one?)


Any ideas?

 

Dizzy module is an amplifier. If it was dodgy you'd get a weak spark, maybe none, I'm not sure...

Have you tried a different dizzy cap?

 

first time I tested it was very weak.... then nothing.

Not tried a new cap as it was only changed recently..... worth a try though

 

could try getting another dizzy from the breakers and try that. thats got to be the easiest and cheapest option if you are still raking your brains

 

Yeah, but try finding an XR2 in a Scottish scrappy

 

Update:

Tried a different dizzy (many thanks to Marv).
No Change!

Sparking intermittently on two cylinders only and not at all on the other two.

Anyone able to tell me exactly what signals should be going into the ignition module?
I've got-
3. Blue Wire - 12v
2. Brown wire - Earth
1. yellow Green - nothing now but was 12v earlier (but also tried adding 12v with no effect!)

Basic stuff-
Coil - 12v and an earth is all it needs?


This is really puzzling me........

 

as said on FT, if things are bad i might come and look for you new dogs have kept me busy so ill try to get clear

 

Cheers for the offer, feel free to come round!

Going to get stuck in tomorrow..... have to get it sorted pronto!

 

pull the ht lead off and put it near an earth then turn it over if no spark disconect the plug off the dissy and bridge the 2 termals quickly as in on and off you should see a spark jumping off the ht lead if so its the dissy if not then??????????????????????? you have checked every think else i would check lol

 

I've answered this over on XRTWO.com.

The green cable goes to the coil. The same point that also goes form the coil to the rev counter (also green).
At least thats how the amp module connects in a mk3 fes CVH - which is the same dizzy.

 

Sorted at last today!

Bloody electrics!

Many thanks for the advice!

 

What was the problem
