Do you have a aftermarket tach?

do you have a aftermarket tach?

no. All factory

Your rotor spins when you crank it so you know you didnt lose a timing chain? I actually had some thing similar happen once but the crank snapped.. No noise or anything, just like I turned off the key

Have you checked the resistor?

 

[coastalcowboy]

yes. rotor turns. have checked piston movement. really stumped. getting fuel. does the ecm effect spark. I have checked and been told yes and no.

83 is older than I am, so I'm not sure about the engine but if this applies check the wires from the distributer to the block... and maybe IAC... just a shot in the dark as I sit at the bar.

Check the power supply going to the ignition module(Square aluminum box). Make sure the power and ground is good with key on . There's also a fuse for the ECU on the fuse block, make sure thats not blown. Check that as well for a 12v or battery voltage.

Do you have the ceramic resistor block on the firewall?

Thanks for all the suggestions. Spent two days tracing wires,cleaning grounds and reworking connections. still no fire. Performed the nutter bypass and BINGO first turn Red Riding Hood busted off. Still have adjust time. Looks alot cleaner under the hood and should make future electrical repairs really easy. Be haulen down national seashore this weekend with my Partners from the Piney Woods. Thanks everyone.
