I’ve got a 93 z28 long tube tube headers t56 I had an engine bay small fire burnt my wiring harness pretty bad replaced my entire wiring harness with one out of a 1995 z28 t56 I’m having trouble getting spark I’ve got power to my coil and power to my opti plug don’t understand why it’s not getting fire any help would be much appreciated.

 

Check opti connector. Are you running original or one that came with new harness?
I believe 95 would be a vented opti so the plug is different.

 

Yes sir I bought the adapter to change it back to a 93 plug I’ve got power running through my plug I just don’t know if the ecm is putting out the right signal to make it all work is there any tests I can run with a volt meter etc to tell if it’s sending the right resolution?

 

Maybe pics might help us see what you've got going on. Also, refer to this site for almost anything troubleshooting on the 93-97 F body: http://shbox.com/1/4th_gen_tech2.html#opti_test

 

One more thing- which one of these do the connectors to your computer look like?

 

Check ground on driver side head.
make sure it is properly connected.
you can also add another ground from head to chassis.

 

^^^^ This 100%. My 93 has the top plugs, a 95 would have the bottom plugs.
