Hey gang,

Has anyone here had any experience getting a LS system to fire?

I have a 2008 5.3L just installed into my '57 stepper with the DOD now removed, new cam and lifters installed by a GM tech and a FiTech Ultimate LS injection system installed. FiTech says all their wiring is correct, but no fire to the plugs.

Thanks,

Ken
