This doesn't make since to me guys, Spark at coil and no spark at any plug. Cap and rotor are new. What are the chances the cap is bad? is there something else I could be over looking?

 

have u replaced ur iginitor i had same problem my truck died going down the road and my iginitor went out and the wires to the clip and come out of the clip that plugs into the iginitor so i replaced it and driped some solder in the clip to hold the wires and vrooom truck started

 

Yeah, replacing the ignitor is what got me spark at the coil. But for some reason it isnt making the rest of the journey. Can the coil spark be weak, or intermittent?

 

Hey Jollyradar...I am having the same problem with my 1991 4runner. I have no spark at the distributor...no power there...have you found a solution to your problem? I replaced igniter, coil, plugs, wires, starter, distributor, alternator and it is a charged battery...any suggestions at all??????? I'm at a loss here...thanks!!!

 

Oh yeah...I also replaced the ECU with one I found on the forum here...just fyi and looking for solutions...

 

I'm still working on it.. just like you I'm at a loss. The next thing on my list is the ECU. I'll keep you updated on this.

 

Thanks man...I think my next step is the dealership...what I wanted to avoid. Let me know and I will you...thanks!!!

*Update* Solved

Ok lesson learned. The first thing I replaced was the coil wire. The second thing I replaced was the coil. When that didn't fix it I returned the coil. Next I replaced the Ignitor and that did produce a spark at the coil. However this was a weak spark. Yellow/Orange sparks are weak. A good spark at coil will be Blue and will give a good *Crack* sound. So everything I did after that had nothing to do with the problem because I was still not getting good spark at coil. I replaced the coil against all odds that it was actually bad and the truck fired right up.

My old coil tested with in specs and produced spark but not a good blue cracking spark.
So my MSD Blaster 2 coil did go bad within specs.
Best guess is that a bad coil wire (and I have known it was bad for awhile) or a corroded Ignitor connection caused a chain reaction.

Anyway wanted this to be topic to be closed and complete for the next guy who deals with this.
