Thanks for the info but I dont think I have that problem my ign and coil pack line up just fine I have never needed a adapter If that is what that is refering to
how would that play a part in my problem
I looking for any thing at this point
thanks

Well I didnt think I needed help acording to that site you told me about it is connected that way but still its like its out of time
what would cause not enough timing on start up??
The more I dig the more that it seems to not have enough of timing to start with it spitting and poping and kicking back on the starter
Its either the ECM or the ESC (Electronic Spark Control )module I am still trying to figure what it does besides working with the knock sensor
my computer is going down for some upgrades should have it back in @ a week hope to have some answer for yall then
thanks for all the help

Check the interrupter ring on your harmonic balancer. I've seen them come loose and rotate on the balancer. Also have seen where the ring slips forward on one side causing the interrupter to miss the crank sensor, causing no spark.
Also, check to see if the interrupter ring on the cam sensor has come loose. If that happens, the car will start...sometimes. Then you'll have stumbling and hesitation you can't believe. Both sensors play into the startup ignition timing and fuel timing. The default startup timing is 15 deg. BTDC, so the car will start normally as long as the sensors are right. Kicking back during startup is an indication of fuel timing out of whack, or spark at all the wrong places.
Just for grins, make sure your plug wires are in the right place. they should line up with the embossed location on the top of the coil pack. Look www.casperselectronics.com
HERE for information on how the coil module is routed. DOUBLE-CHECK the wiring!

Since I connected my CCCI to the coil pack wrong the first time and the car would not start, but I had both spark and fuel.
Since the ignition module has the cable connectors to the ECM and faces the DS and the coil pack has the EVEN number coil plugs face the front of the car it becomes a no-brainer.
Near the coil pak 4 plug connector the ign module yellow wire connects
Near the coil pak 2 plug connector the ign module green wire connects
Near the coil pak 6 plug connector the ign module blue/black wire connects
Maybe this makes some sense

Just a bacic question, have you tested all your grounds? The ones behind the passenger head by the firewall.
Just a quick update on mine, Once again I pinned out a few wires on the oem harness, cam +, cam lo, crank hi, esc, bypass, etc. I also put in Johns splice kit. No luck yet tho. Only runs on the 1 coil/module. We'll keep picking away at it tho.
For the engine runnin like ****, I backed the rockers off to .005 clearance and it runs great. Im swaping in a set of lifters as we speak, should have it running again tonite.

Ok I think it has been 2 weeks now and I have invented a few new bad words
I HAVE REPLACED EVERY DAMN THING
ign module 4 times, ign module connecter, ecm, crank sensor, the cam still checks good, maf sensor, I put my old stock chip in for the hell of it and nothing
I have ohmed out every damn wire going and coming for all sensor
I still think it is the ign module it will fire but its like it is out of time
kicking back on the starter and back firing
I have no idea what elese to do
is there any one that lives around the upstate of SC that could help with this problem or any that I could call
thanks for all the help
one hell of a learning experience

Textbook symptoms of a bad cam sensor or being off by one cylinder. Pay attention to #10 in the following write-up by Tom Chou.

I checked the ring on the crank/pully and it was tight and no signs of slipping I have a new crank sensor and it checks ok what elese would cause this problem

Just a quick update on my POS. On the 86 it will run on 2 different new coil/modules and the 87 will run on the original(replaced 2 years ago). But NEITHER car will run with the other cars ignition.
If I dont figure this out, I think i'll switch to a crack habbit..Its gotta be cheaper.

I have the same problem I ordered a new module from g-body parts and im not getting any spark either. Im talking to someone else who thought their module was fried but it turned out to be the crank sensor. Ill get back to when I here from him

I went thru this a week ago.
Bought a new coil pak from a reputable vendor on the board and an ignition module
from non other than Auto zone.
In fact I asked the board about them earlier, and if you track my posts most said do not buy them from A.Z.
Put the new coil on the new ignition module, car absolutely would not start.
Put my old coil pak and old module back on, car fired right up
Switched the new ones back on, deader than a door nail.
Promptly took the ignition module back to A.Z. and asked them to test it.
Said they had just sent their tester out for repairs and offered a exchange or refund.
Took the refund and will definetly buy only a DELCO ignition module.
Do I know for sure it was the module and not the coil pak.
Nope, but when I get the new delco module I will
Good luck
