U1000 code will spin over, has spark, no fuel?

ANY help would be greatly appreciated.
I didn't check the cig/acc fuse cause I didn't think it would have anything to do with it, but I've been thinking its a ground strap somewhere.
The block is also grounded with a 4 gauge in place of the factory ground for the battery since I relocated it to the back. What's got me is its ONLY fuel injectors and water/oil pressure gauges. The fuel pp primes, I have pressure at the rail according to the gauge, but the injectors won't fire and the 2 gauges won't budge like the rest. I pulled the rail and spun it over just to make sure the injectors weren't firing and sure enough, there not.
I really need my car back.
