I have a 94 s-10 4.3 and am having some serious issues in relation to starting. Whenever I turn the key over to start it, it hesitates a lot, almost like the battery is dead but after a second or 2 of forcing to turn over the engine, it kicks in and starts. At first I though my sub was killing the battery, so I have tried driving around one day with the sub turned completely off but still no change. The I figured it might be the timing because I believed the previous owner advanced the timing but still no change. It runs a little better and made a slight difference for a couple starts but after that, it went back to forcing to turn over. I have recently changed distributor as well as plugs and wires hoping it may solve my problem but again, no help. I forgot to mention that maybe once out of every ten starts, it will start "almost" normal.
Any help would be appreciated. Thanks
