93 won't run....help

I am asking for a friend, but i'm at a loss to help him and looking for ideas. 93 6 speed with 95k. new opti, new cap and rotor, new plugs and wires, new ignition module, new coil. Intermittant problem. causes tach to fluctuate eratically and car will not continue to run. tried to pull a code, but could not remember the paper clip trick details.
any ideas would be greatly appreciated
thanks david

My ALDL is the 16 pin, but I think the 93 pins are the A & B pins. There's another post (just recently) that listed all the various LT1 combinations.

Here...about midway down the page, I posted how to pull ECM codes and CCM codes.

Same thing happened to me.

Replaced the same parts you did.

New ECM did the trick.

Just an idea.

Opps, forgot something.

Just 12's. :smash: :smash: :smash:

Re: 93 won't run....help (hotwilzz)

I am assuming that you unplugged the harness that goes to the coil and coil driver (on the front passenger side of the head)? I had a similiar issue a few weeks back. My car would drive around fine, but above 5k it was like I was hitting the rev limiter. Anyway I chased the problem for a few days and finally came up with the conclusion that the harness that plugs into the coil driver was not making contact at high RPM's because of more vibration at a higher RPM. I had to bend the harness terminals a little so that they would fit tight on the terminals on the coil driver. Also if you unplugged the connector that plugs together at about the center of the intake on the passenger side, make sure that you are getting continuity through the connector (test each wire on both sides of the connector). Let me know what you find out.
