I was driving my repu the other day and everything was running good except alittle rich but now it won't start and I have no spark at the plugs.Everything is getting power but no spark.I have new wires, plugs, cap and rotor and still nothing.Ideas?I thought its best to post here seeing as it is using first gen ignition parts.

No spark at any of the plugs? How about the coils? Did you try swapping ignitors? Check your grounds?

yah, make sure you're getting power to the coils and ignitors, if yes then the ignitors are prolly bad. odd for both to die at once though....

Update.......

I have power to the cap and ignitors.Could the pickups in the distributor just go bad?Its the only thing I can come up with.

Yeah,It's the only thing tho that doesn't check out tho.Everything else is good when I tested it.I thought for sure it was the ignitors and tried others but they weren't bad on the resistence tests.I'll price out the pickups today and see what the will ding me.I will try some other things first tho.

I would still place odds on this ignition module, try the GMC conversion they are about 25$ech vs the 140$ech for the mitsu ones. Or a connection with them. Are you losing spark all the time and on all coils?

None of the tests work reliably. I've had good ignitors fail tests and bad ignitors pass. The only good test of an ignitor is to run it. Go to Pull-A-Part and nab a handful, or swap your leading ignitor with a known good one from a buddy's RX-7.

Tried different ignitors and still no good.I'll play with it some more.I was told its cheaper to buy a used distributor than to buy new pick-ups so I need to narrow it down some more.On the plus side I wired it for DLDFIS.But still nothing.Used up the extra ignition parts I had kicking around tho.

What module?You mean ignitors?I have no spark at all.I drove it one day and nothing the next.Thats what has me baffled.
