    check your fuel rail. usually the fuel rail pops out of the intake with the injectors attached. sqiurts fuel and won't start. you might need to pull the fuel rail and get better o-rings. replace both intake and rail o-rings. good time to clean or upgrade the injectors while at it and check the fpr.

    A ruptured diaphragm in the fuel pressure regulator can allow fuel to feed into the manifold thru the vacuum line.
