Picked up the wife a 94 Accord LX a few weeks ago. Last Thursday while driving, it bogged real quick then ran fine. She got a few miles up the road and it quit on her(she coasted to the front of the house). I checked for spark at the coil and according to my spark tester, I'm not getting spark. I bought a coil from a local guy off Craigslist, put it on and still no spark. I put the tester on my 91 Accord and it showed the tester is working.
If there is no spark from the coil to the dizzy, it has to be the coil right?
My car, the coil is in the dizzy, while hers is external.

I did a search and some people mentioned the ignitor. Isn't that in the dizzy? If that was bad, I should get spark from the coil but not from any of the wires from the dizzy.
I dont wanna fork out $75 for a new coil and that not be it. I know you guys are pretty damn good(gotten solid advice in the past with my car)and could help me out. Wish I could get the $40 back from the guy I bought that coil from....

 

Think of the ignitor much the same way you would the ignition module in an HEI GM setup. It controls (along with the ECM) the ignition system.
The Ignitor Controls the coil, not visa/versa. If you're not getting spark from the coil, it will be because of several things.
The coil requires battery voltage to energize.
The coil requires a signal to release that energy.

I'd suspect the ignitor as well. Then again, I've the luxury of having a known good sample to test my theory with. If I'm wrong, I haven't spent any of my (or my customers) money finding out.

From the sounds of it, you don't have the luxury of guessing. Money's tight, I know. But it may be far cheaper (in the long run) to have it looked at by someone local with the equipment to fix it right the first time.

Thanks for the reply P Adams.
The coil is getting battery voltage, I checked that.
Isn't the ignitor in the dizzy? If so, the ignitor sends a signal through the wire to the coil and the coil sends spark through the same wire back to the dizzy?

 

OK, I just looked up part numbers for the control module. They are the same between my 91 and the wifes 94. Im gonna swap those out. If that doesnt start the car, it should be the coil.... right?

 

I'd suggest swapping ignitors and report back.

You have to remember how this system works. ECM, IGNITOR, COIL, DISTRIBUTOR CAP, WIRES and PLUGS.
You have to ask yourself "Why the ECM?"
It takes signals from such sensors as the TDC sensor and others to determine when the spark should be delivered.
Of all the components involved, the most common and easiest to access is the Ignitor. That's why I'm pointing you in that direction - law of averages

If it fixes it, great. If not; you haven't spent money needlessly and we can continue this quest for truth and justice - the American way.

Ok, just swapped the control module(ignitor) with a known good one from my old dizzy... SHE'S ALIVE!!
Thank you so much P Adams for your time and expertise!

 

Glad I could help. (It is a community effort anyway)
