I'm in a little bind because I cannot find my Chilton book.(It'll show up when I don't need it)

Anyhow, just out of the blue the BII won't start...not misfiring, just sounds like it' only firing on a couple cylinders. It sorta keeps running as long as I'm cranking it over, but as soon as I stop cranking it dies.

I thought it was the TFI module for sure, but I replaced it and no change. So I guess the coils next. (Cap, rotor,wires, plugs ... all that stuffs pretty new).

I gave it a good shot of starter fluid, (ether), in the throttle body to see if it'd take off.... still the same, so it must be ignition.

So now, how to replace pick-up coil. I have the cap, the rotor and the metal plate with the six segments that pass thru the coils field all off. The coil is under the dist. shaft. Do I have to pull the dist. ??

Thanks guys, dave.

How do you get the

If you are doing this "In the vehicle" My many sympathies to you!
The easiest thing to do is note rotor position and outside body position of the dizzy, remove the bolt and clamp and remove the dizzy.

Here is a little trick I learned about years ago. When you are ready to pull the dizzy mark the installed position and as you raise the dizzy you will see the rotor turn slightly. When it quits turning mark that position on the dizzy.

Now to install position the rotor to the second mark and line up the body to where it was in the beginning. Slowly drop the dizzy and watch the rotor as the gears engage. You will see the rotor point back to the original position as the dizzy settles.

Another trick is to get the oil pump drive shaft engaged with the dist. I worry about the rotor position first and if the dist refuses to set down fully I just rotate the engine slightly and make sure the distributor remains engaged with the gear as the distributor rotates the oil pump shaft will engage and allow the distributor to seat properly.

Good Luck!!

Thanks tek,
I guess you agree I should change the the pick-up coil next, huh? Anyhow, thats where I'm going next.

I undestand what your saying about watching the rotor as i raise the dist. Is it easy to get it a tooth off when re-installing? I mean, if it's off a tooth is it quite noticable looking at the lines I make or is one tooth off just a very slight mismatch of the lines?

It's 11:30 PM out here on the east coast, so I'll be doing this tommorrow morning. dave


Almost forgot to ask.... once out, how do you get the coil off? You have to take the drive gear off the shaft end and then pull the shaft out of the dist? Is there a rollpin or something holding the drive gear on the shaft? Thanks.
