i bought a new coil, ignition module and opti and starter.But the car i checked the coil spark and nothing so i got another one an nothing again. its weird cause it turned on the first it i tried it. then turned it off and no theres no fire. Does anyone know what it might be? any help is good. thanks.

I'm assuming you changed the wires with all the new parts, and seated them properly, in the right order?

I guess you could check your grounds on the coil. Perform the opti and spark test per shoebox's website, see where it fails.

As always, Shoebox has a good guide in troubleshooting through some of the ignition system: http://shbox.com/1/4th_gen_tech2.html#opti_test Have you checked the connections on the opti harness itself, that would be a good place to start.
