    I just finally got my engine rebuilt and put in and everything fixed after the fire. I have fuel and air. No spark. Torque app shows its cranking around 130-170 rpms and sucking in 140cfm. Plugs are wet. Tried a different known working ignition module and same thing. Any ideas

    I think I narrowed it to the crank sensor. The 18k pulse is working but the other reads a flat 6v all the time
