When i moved coil pack 5/2 to 6/3'* spot, and started the car, terminal 5 on coil pack 5/2 still did not fire, yet on coil 6/3 both terminals sparked.
OK, so when you said #5 was not sparking, you didn't mean position/cylinder #5, you meant the terminal on the coil with the #5 next to it, wherever that coil was placed, it did not make a spark.

Are you getting a spark from the other terminal on the same coil (#2)?

yes i am getting spark from terminal 2 on the coil.
And yes i mean there is no spark coming from terminal 5 on the coil pack itself.
Regardless of were its moved to.

Save the coil. It'* a collector'* item

I smell a rat (no offense Al). The secondary terminals on that coil are both attached to one end of it. If that secondary is bad......wait, what did you read across for resistance? I'm losing track of this drama.

Anyways tomorrow is my last day with the Bonneville, im parking it in my grandparents garage for a month or so, i need to do some serious catching up on my fundage. Also I will be driving the car that they dont need nor the one that they use, its a 89 Toyota Camry V6, its not a bad car. Gets awesome gas mileage, takes regular only, and all i have to do is pay my grandparents for the insurance, which is 30 dollars per month. Very cheap to drive compared to 200 dollars a month for insurance. I want to save up and buy some more parts and peices, possibly a flowmaster muffler, smaller pulley, bigger idler,power steering pump, those type of things.
The oil in the Bonnie smells like gas, and im sure if i lit a match in it, it would burn. Tomorrow it will be on the road for around 20 minutes total! Very small trips.

Al Do not cancel my order!
I'll Proceed with your order as planned then!

I'm also glad it'* just the coil too.

It will be parked for about a month so i can catch up, and buy some more things for it, until then im using a 89 Toyota Camry, my grandpartens loaned it to me, all i have to do is maintain it and put gas in it!. The bonneville is parked in there garage. I snapped a pic of it today just after i parked it inside the garage.


Of course i had to wash it first!

And Bill, the resitance was .65 ohms, as i recall, i think.

If the resistance of that coil was 6.5 ohms across the secondaries, the coil couldn't cause one of the two cylinders to misfire, bud. Not possible. If that was your secondary resistance, both cylinders would be misfiring, as that'* almost a dead short. Or was that the primary resistance?

it would of been seconday, as it was across the two top terminals. It makes no sense, werever the coil is moved, #5 is still non working right off the secondary terminal.

If the secondary resistance is what you say it is on that coil, that coil is bad. But also bad to the point that neither cylinder being suppied by that coil would fire.

Are you sure you're checking this right?

that'* a damn good idea. Get closeups of the electrodes. All in a row. I like your style, Don.
