I have a 95 cavalier 2.2 with no spark. It turns over fine, changed the crank sensor, had the ignition module checked. Is there a flow chart with steps to use in troubleshooting? Its not in my Chiltons.

...this may seem obvious but did you check the plugs and wires.


Cause that would make me go "tee hee" if you hadn't

What do you think the chances of four plugs and four wires all going bad simultaneously are? Think before you reply.

I replaced all 4 plugs and wires. I have no spark coming from the wires. The coils both check good, so does the control module.

How did you check the coils and control module?

The problem with these situations, is that it's fairly easy for an electrical trades guy to fault find, but hobby mechanics don't have the gear or training. That's not to say you aren't capable, but it might be less hassle and less expensive to just have an auto electrician rectify, rather than replacing stuff that may be quite satisfactory.

No Codes come up on the reader. The SES light is not coming on either. copied pages From The Service manual they don't let you check them out of the library. But most of it is differant the book is for a 91.
