Thanks to all for sharing .... Wife's Chevy venture has been stalling and getting progressively worse, now won't start. I surfed the web this morning finding numberous builltien boards and a common theme in most, crank sensor, fuel pump, or the wire harness connector under car behind drivers seat. Easies (and cheapest) to check was electrical connector. First, confirm symptom, turn key and listen under car, no fule pump hum. Pulled connector and reseated a couple times, try again, car starts. Examine connector and sure enough the one pin is discolored around it in the connector. Clear sign that there is excessive current draw, causing heat, causing oxidation, etc. Eventually you end up with an "open circuit". Small file, contact cleaner and short time later, car starts better than it has in months. My experience in a similar inductry, this is a temporary fix. Once these connectors and pins get damaged, they will eventually need to be replaced. When that time comes, I will cut the wires and install another heavier connector for the fuel pump circuit. Thanks to all for sharing, it led me in teh right direction, and I suggest everyone wiht similar issue, listen for fuel pump hum when you turn teh key, and if you don't hear it, go to this connector first!
