Welcome to CAC!!!
enjoy!!

is the fuel pump working????
also check in the crossfire injection Mine,they are specifically for the crossfire vettes.

Welcome to CAC!!!

I second that!

KYKID- If you have fuel and then you don't... it sounds like its a fuel pump issue. Not enough voltage or a defective pump.

Since it has been a while- and sat a while where seals, gaskets, and things could dry out- I'd suggest rebuilding the pressure regulator and the gaskets & seals on the injector towers as a precaution.

If I remember correctly... to get a voltage on the injectors at their terminals... it must be running or at least turning.

Also- the fuel injectors won't open up unless there is oil pressure and the engine is running if I recall. That's to prevent it from creating a fire hazard where the injectors and fuel pump would keep going and meanwhile the engine had a catastrophic event occur (blown apart or something).


So you'd need to test for voltage while cranking. If you don't have voltage... it might not be the injectors.

was showing I had oil pressure while I was spraying fuel in with a bottle and running checked with nome light while I was turning it over

That's good to know- sounds like your 10 year old injectors may be the problem then. Used injectors can be questionable- so I would assume injectors not fired in 10 years could be highly questionable.

If you have voltage when you should and the lines are pressurizing, then it sounds like the injectors are bad.

If everything else is good... It would be logical for that to be your problem.

Stock injectors were 64/66 lb units if I recall. So, if it is stock you may want to replace them with identically sized injectors.
