August 14, 2011I have a 1991 Chevy K5 Blazer 4x4. Truck ran perfect. I put some old gas in it, truck ran fine all night. I parked it that night it was fine. Started it the following morning and it would not start. I removed the old gas, changed the fuel filter and spark plugs. Now it will start but wouldn`t stay running unless I hold the gas pedal to the floor. Also when it starts it has no power. Any suggestions on anything else I should check or change to resolve this issue?
