trying to hookup summit racing box. hooked it up no spark called summit tech bad box.got another hooked up got spark when doing test but no fire when hooked up.everything worked with factory box before summit box. i narrowed down to distributor how to test to make sure it is the distributor.

before you start throwing parts at it, can you put back the original ign and test it that way? have you changed anything with the distributor to make you suspect it went south?

We had same problem on the Duster. Wired it up just like instructions said but no fire. We switched the two distributor wires and its worked fine ever since.
