If it has sat for any length of time....or you possibly got some bad gas....try using some SeaFoam in the fuel. Add 4 oz's to a tank full and drive for at least 20 minutes to help get any "possible" water / moisture out of the tank. You can buy it at most auto parts stores like Napa or whatever you have where you live.
