I have a 1991 corvette and it will run as long as u squirt gas in the inake. It has plenty of gas to the gas rail. It also has  new fuel pump and filter. I'm not sure what else to do to get it to run. I would apprecite any help i can get.

you said "any" help, so here goes. for background, I know about all there is to know about the 63 - 67 series, so here goes.

Obviously you haven't cured the fuel delivery problem yet. My next guess is the fuel injectors are not operating, either there is a pre-filter or something still blocking fuel to the injectors or the fuel rail or there is no voltage getting to the injectors allowing them to operate. There must be a fuel injector controller somewhere that is not functioning if this is the problem, and it sounds like all of the injectors are effected, so my guess is there is some sort of an electrical problem with the FI controller. I am not sure how you would go about checking this, perhaps something simple like removing an injector and turning the car on to see if you get fuel, though it would be much safer to disconnect the electrical connection to the injector and measure with a volt meter while cranking the engine. Should get some kind of voltage reading, though intermittent because the injector does not run continuously.

Do you have a shop manual?

Is there a dashboard indicator light telling you there is a problem with the fuel injector system?

I hope this gets you started down the right path to fixing the problem.
