Thanks for all the help. Soooo I think I know what's wrong the car will start for a second if it's been sitting for an hour or so. I think the injectors are clogged or not working. They were new injectors they were from a friend that works at Magnuson Superchargers. I think the were sitting for some time as the car smells like stale fuel. Either the injectors aren't getting power or the injectors are clogged. Testing that tomorrow. If all else fails I got a guy coming to look at it this Sunday.

LS ECM
You need 12v switched power to the PSI fuse box.
The ECM is powered up with ign 12v. When you turn the key on the ignition and fuel pump relays close.
When you hit start the purple wire provides 12v to the starter.
From PSI
NO-START
1. Red Ignition Wire (From back of Fuse/Relay Center) has 12-volts with the Key in the ON
position and CRANKING position. This cannot be stressed enough, most NO-START
conditions can be traced to this wiring issue.
2. Check that 2 Large Ring Terminals by Crank Sensor are connected to CONSTANT POWER.
Batt. Battery Positive (2 LARGE RING TERMINALS COVERED IN BLACK HEAT
SHRINK), These are often mistaken for ground wires because of the black heat shrink
