What kind of computer are you using to run it all? LS2 or LS1 style?

02' ls1 style, 24tooth reluctor with cable throttle. I'm wondering if the place i'm getting key on, or ignition power is correct. from the fuse panel to a relay excited by keyon. but, does the power stay hot when cranking? or does that matter?

Definitely check that out. Hopefully that's it. I've done the same thing with an MSD box.

so, when the motor is cranking.....does the computer need a hot signal while cranking......i don't think it's getting fire.

Yes, I think that's the case. If there's no power to the computer, how can it do anything? Are you getting any fuel?

I found that bleeding the air out of the fuel rail via the Schraeder valve was key during the initial start-up following a replacement of the fuel system. Once that happened, it was beautiful noise.

Good luck.
