Coil Pack Question

[BarryBum]

Hi again, I am still thinking about picking up this 84 Grand National. Currently the car is not running, it is supposed to have a rebuilt engine, turbo and trans. But, the car has not run since he got it back from the shop??? The owner says it needs a coil pack, I have not yet seen the car, but he says that he is getting fire to the coil but none out of it to the plugs.
What do you thinK????
How big of a deal is this???
Any other ideas?

Quick change in about 20 minutes. Nothing needs to come out of the car.

Of course, if the coils aren't bad, then I'd make him agree BEFORE you commit to pick up the tab if the car doesn't run.

Autozone prices: 50 or 100 bucks (2 different brands).

I went with the cheaper brand and mine runs fine.

The 84-85's use a different and much more expensive module and I think the same coilpack, compared to the 86-87's, so make sure it's the coilpack and not the module. www.casperselectronics.com has an adaptor harness to let you convert to the 87 style.

That's right, my bad...sorry about that.

If it happens to be just the coil pack you can use a '87 style with a plastic coil adaptor that goes in between the coil and '84 module. Cost is about $10-11 for adaptor and is available at AZ or Advanced. No alteration to module plug wiring. Cheapest price for '87 coil is probably the $50 one from AZ. The $100 one is the Accel coil. The Accel one comes with the coil adaptor plate.

Could try checking resistance at the terminals on the coil pack first with a ohm meter to see if there is a obvious problem with it.

Thanks, 6sense. I knew the modules were different but I thought the coilpacks were the same, and checked by looking at an accel ad that said their unit fit 84-87, sigh .
