    Default BBC CNP 558-117 No Start Issue

    I have a new BBC with a Terminator that was Built and Dyno'ed with my Terminator ECU (known good tuning/setup file) 558-117 harness. I've now installed it in the car and all the prestart checks look good. When dyno'ed, it was with a Holley dual sync & CD box. I've changed this over to a blank cap on the dual sync distributor with LSx coils and correct GM sub-harness. The correct system parameters have been changed to DIS Coil On Plug and a Dwell Time of 3.5ms.

    I have a no start condition and I'm wondering if the I need to resync/setup the dual sync distributor? I wouldn't think so, but wanted to check. Any other areas I need to check first to save me some troubleshooting time? I have run through the no-start checks posted here and everything looks good at this point.

    Check the ignition timing synchronization first.

    Cranking Timing appears to be about 70° advanced when using timing light on #1 CNP LS coil. I am getting spark. Traced all the coil wires from harness to coils and everything is in it's proper place. The dual sync was setup with rotor & distributor cap per instructions and video. Currently blank cap is on it with LS CNP. Now a dual sync with blank cap question. Can I just rotate the distributor to bring it back to 15°? Or do I need setup the cam & crank sensors again on the dual sync? If so, do instructions exist for setting up the dual sync with no rotor and blank cap using CNP? Thanks as always!
