Ls1 injectors not working. Need help!! I have a heads/cam ls1 in my 2000 silverado. The truck was running perfect. I just installed the holley sniper intake manifold and now no start. I norrowed it down to fuel injectors aren't pulsing. Ive turned off vats, all grounds are good. All i did was swap intakes and now there not working.

Whats with all of the guys swapping Sniper intakes into their trucks? Seems like a lot of money to spend to lose 30 ft-lbs with no gain in usable HP.
If you didn't change anything but the intake, why are you blaming the injectors?
What did you do with the MAP sensor? Are you using your stock throttle body? What did you do with the stock fuel pressure regulator?
