84 Corvette
This does not really have to do with a Camaro or Firebird but it has to do with a C4 Corvette. My ex-girlfriend has an 84 Corvette and it will not start. It has a new battery, it has spark at the plugs, but no fuel is coming from the injectors(Cross-Fire Injection). The fuel pump is pumping fuel, the fuel filter is not clogged, and there is fuel going to the throttle bodies. There is no fuel however coming out of either injector. We poured gas right into the intake and it started right up. It has been sitting for 5 years. Please help.

check the resistance of the injectors............could possibly be 2 bad injectors.........also are you getting voltage at the injectors?
your ECM might be fried

Are you getting +12 VDC at the injectors? The ECM grounds the circuit to "fire" the injectors, so if the wiring is intact and fuses are good, you should be able to measure voltage with the ignition on.
I don't have any data on the 'Y' cars, but there may be a separate fuse under the hood for injector power.

I really do not have a meter or anything here to check if it has power to it. Is there any way to check it without using a meter?

well a test light will atleast tell you if you are getting any power
but vader is right, with the engine in the run postion there is a 12 volt constant to the injectors
the ECM fires them by grounding them
