Re: 2004 4.3 hard to start after sitting for a couple of days
2 things I have run across.
1. Check/change fuel filter. Folks tend to forget about them since the V* models are in the tanks.
2. How old is the distributor wires/cap/rotor. Mine had spark, but super weak.
A friend of mine had issues with his 4.3 in an S10 and his ended up being the intake spider thing, however being urs is 2004 you should already have the newer design spider.
