hey to all fellow turbo sprint owners...had mine since brand new off showroom floor...30 years of fun..
still don't want to give up on it just yet..

anyway no spark is the issue ...have two working coils so not the problem...seems there is no pulse on the neg side of coil when cranking...
never had an issue like this before ..any help would be appreciated ......

there is a black electronics module positioned on the left strut tower. that's the ignition control unit.

it is most probably bad and in need of a new one. :wink:

Ignitor issues, or distributor module.
Don't rule out wiring as the culprit.
Do you have codes?
My ignitor failed after more than 600,000 miles, it took a bit to sort it out
never having one failed before. It would start, run 60 seconds, then die.
I had another TS fail, distributor wiring harness, broken wire inside the insulation,
took half a day and jiggling the wire harness with a DMM to trace it.
Then I had a rash of ignitors fail on several cars, having stocked up on them,
it was an easy 5 min. diagnosis/part swap to verify. Another one was distributor module
fail, that was harder, replacement dizzy was rebuilt 180 off, so after thinking that was
a good unit, it took a bit to figure out the distributor electronics had actually failed.
Went through the diagnosis tree, and back to what I thought was a good test part,
was not a good test part, reset distributor 180 and all good. Point is original problem
was distributor, I replaced with a known good part, but part was not good. Doh!
Do you have FSM and turbo supplement? Should be all you need.
