Thread: No Start '55 Chevy

  1. #11


    Any updates? Having the same problem here with Terminator X Max on a 24x LM7. Holley said shock grounds and wiring, then replace sensors. So I tried three O'Reilly brands, but nothing changed. Now tech support says us GM sensors, but I threw them away already. Doh! Getting sensors next week (new baby killed play funds), and if that does not work then I’m sending it to Holley. So frustrating.

    Inching forward. I had an issue with the fuel pump relay that also powers the coils and the injectors. I have spark and fuel pulse now, but something is wrong with the timing. It cranks and backfires, no start. It cranks for one revolution until the starter motor stalls dead because of the backfire. I still have a red LED cam indication. I'm just in touch with tech support to get resolved piece by piece. Do you have spark and fuel pulse? Check for +12V at the red injector wire on crank.

    Find TDC on your crank pulley, and verify your timing.

    Default Timing verified, but...

    I watched the Holley YouTube video on timing an LS. I found TDC and made a pointer. I used a Snap On timing light and it verified that I had the 15° of cranking timing in place. I also offset the cranking timing to make it fire at the desired 15°. No run, It backfires though the exhaust now, and still after the second revolution of cranking I get a red cam LED on the ECU. Ignition is set to coil over plug, 4.5 ms Dwell, and cam timing is set for rising edge. I have 88° of negative timing offset to make the timing light fire at the 15° BTDC mark. I sent the datalog and Global Config File to tech support.
