Line up your crank trigger wheel and timing pointer on number one cylinder.......pull the cap off and see where the rotor is pointing to in the cap.....if something happened to the distributer or cam you should see it there...Rotor should be pointing somewhere close to number one terminal in the cap. I would bet it is not....and something failed like Lee pointed to.....

Do you send the crank trigger signal into your ECU and then to your ignition box......or bypass the ECU and direct to the ignition box with locked timing....?

I ran my LT-1 with locked timing and did not use the ECU to change the timing.....
