I just rebuilt the 2.8 v6 motor in my 86 Camaro and now have no spark. The engine will crank but no spark at coil. There is power comming from one of the wires from the distributor to coil. Not sure what to check next? It ran when dissasembled (bad crank bearings). I think something may not be plugged in or shorted during reassembly. Help?

Unfortunitely I also have one of these. I just went through the same problem. Turned out to be a bad ignition module (IM). I have been through three of them. You can have the IM tested for free at most major parts houses.

Are there any trouble codes stored in the Computer?

Question

Thanks for responding, I checked the computer for trouble codes and got 1 flash, pause,2 flashes. My maunal doesn't list that code. Maybe it's in the factory manual. Anybody know?

The 12 code means it is operating normally. The usual is three code 12's followed by any trouble codes (Three at a time), then back to a code 12.

Try here: http://www.euronet.nl/users/fo_elmo/techno.htm

It is a fiero site, but the computer codes and diagnostic link are the same.

Cool

Pete lemme be of some assistance to you if I can...I just had another 2.8 in my car and had the same problem right off the bat. What I found was that the coil was getting 6 volts instead of the 1/2 volt that it requires. That can blow the coil right off. Give that a check and see how many volts that coil is getting. Should fix the problem. Grab you an ignition module...
