The problem seems to be that my injectors are not firing. I checked and they are not stuck and work but when i try to start the car they don't fire. Also when i tried to use the signal from the computer to turn on the fuel pump it did not work. I think it might me related. I am using a vats bypass chip and it is set to send 50Hz signal to the dark blue wire going into the computer #11 on the Red plug.(98 ls1 computer) I ended up putting the fuel pump on a switch and i can turn it on but injectors fail to fire. Following is a link to the diagram i used. I ignored the three relays for the fans and using a different system for them. What could be causing the injectors not to fire? I went trough the diagram multiple times and i have everything wired exactly the same.

ok i figured out the main problem. I hooked up the voltmeter to the connector for the injector and the voltage went crazy when cranking so the computer was sending pulses to the injector to fire. Before i loosened the fuel line to see if any fuel comes out and fuel did spray out, but today i checked again and fuel comes out but very little so something is wrong with my fuel pump. Still don't know why the computer is refusing to send a signal to turn on the fuel pump tho.

 

The VATS module sends the ground signal to the fuel pump relay. You will need to ground that wire since you are not running the security module.
