I have an 1991 EA82T, bought a 1979 Suzuki Samari rock crawler with this engine in it. Was running when I bought it, then I had a fire and burnt the engine wiring harness up. With the help or wiring diagrams and spare harnes got the wiring harness rebuilt. All was good until I went to start it, no spark, I have read a number of posts looking for answers. Made sure a had lots of good grounds for the engine, the timings belts good, had a couple spare coils with ignitors and also distributors. Grounding out the neg on the coil i get a spark. With the distributor removed from the engine if I turn it slowly I get spark at all the plugs as soon as it turn the distributor faster, no spark?

 

Thanks for any info you can provide,

The trouble may be with the ignitor.
