It sounds like air in the fuel system

I recently had some starting trouble with my Colorado. Once it finally started it ran fine but it was a pig to start

I finally traced the problem to air getting into the fuel system. I changed the fuel filter, replaced all the jubilee clips from the filter to the fuel pump still to no avail. Unfortunately the only direction to go then was underneath (to the fuel tank).

I took the fuel tank off and discovered that the fuel pick-up pipe had a hole in it. Once repaired the problem was cured. (the top of the tank seems to be a water trap).

Not sure if this is the problem with your's but it could be another direction to go in.
