lq9/ls3 build first start No injector pulse installed a lq9/ls3 with custom cam, fast intake, fast injectors, fast fuel rails in a g-body. Turns over but no start. Put key in on position 60 psi at fuel rail then immediately drops to 0 psi. Checked injectors 12v with key in on position. Used a Noid light No pulse when starting. When Spraying starter fluid in throttle body, it pops and back fires. What did I do wrong? Is it a bad cam sensor or crank sensor. Or did I install the new cam in backwards? Any help would be great!
