1991 Chevy Suburban V8 Four Wheel Drive Automatic

It won't start I changed pressure reg.& Injectors, getting fuel to valve body, pour in a little gas it will run a few seconds and quit. Fuel seems to be going into the body but nothing comes out.

Hook up a noid light to the fuel injectors and crank the engine it should pulse, both of them. If light doesnt flash then check for +12 volts at one terminal with key on and hte other one should have none, if there is constant ground or no ground when cranking you could have a cks problem or a error with your fuel injector relay if equipped. And maybe even a bad ECM.
