We have a 2000 Blazer 4.3 V6...strange symptoms...first for about a month my wife described a "stutter" on start-up intermittently, so I thought fuel filter and/or water in the fuel...treated those symptoms...the problem seemed to go away...then last Friday I drove her truck to work, it ran great driving in to work, but when I came out at the end of the day it cranked but didn't start. Like it was either not getting fuel or fire. The next morning after leaving it at work overnight it started right up. I didn't really notice if the fuel pump was running Friday.
It has benn running fine since Saturday and then this morning in the garage (thankfully) it wouldn't start again. I made note that the fuel pump doesn't seem to be running. Before I jump in and buy a $300 pump, drop the tank and replace it...has anyone got other ideas to check the pump to see if it is bad or other issues it might be?
Any help would be fantstic!
