2001 Chevy 1500HD EFI Engine started sputtering as I slowed down for turn, lights dimmed back and forth with engine speed. Rough idle. I can pump the pedal and get the rpm up but it sputters again at acceleration and tries to die out. Now it will not start. Battery has life. EFI prime seems to sound different but not sure. Now the engine won't kick over.

It sounds like you may have a problem feeding the fuel to your engine, I had the same problem with my 89 RS. All the 1989 model's fuel systems were recalled. I think you may need a new fuel pump. The fuel pump is located inside the gas tank in the rear of the car right under the rear axle. The fuel pump itself isn't too expensive, but with other small parts such as the electrical harness upgrade and fuel filter and the labor you should be looking somewhere in the $500 range. I hope this helps.

Sounds like a possible vaccume hose leak?

Might be fuel pump, or filter is pluged up, best to chg. filter and then do a fuel pressure test.

check your fuel filter, take an air compressor and blow air through the "in" end if no or little air is coming through then just replace the filter, if fuel filter is ok then try a fuel additive to clean your injectors which are a very common problem when the engine gets gunky build up on them
