it is a reworked harness. when i was spraying started fluid it would sound like it fired a few times but maybe a half a second apart made alot smoke though. its in a 1993 k2500 the engine is a 5.3 from an 04 yukon denali it does have Grey fuel injector plugs which means its the flex fuel version right?

I'm not sure about the flexfuel part, but it sounds reasonable. Every stock injector I've ever seen has been all black.
Does it have stock cam and rockers?

yes (well unless someone switched em before i got it)
Hmmm ok. Well if you are sure that all of the grounds are hooked up and that there is no spark, next place to look would be the wiring to the coils. Let me get some screenshots up of the ignition schematics.

I would start by checking power, ground, and signal wires to the coil packs. If you're not getting spark, one of these will not be working correctly.

An 04 Denali never came with a 5.3. Are you sure all your ducks are in a row? I'll look for another similar topic to link...
Have you read this topic?

It just seemed like a similar problem.
