2002 Mazda B3000 V6 won't stay running
 

Hello to all fellow motorhead's . Working with a 2002 Mazda B3000 Extra Cab 3.0 liter V6 motor automatic transmission V6 will start but not stay running. Throwing up 14 different codes from evap sensor 2 fuel issues and throttle positioning sensor. Any idea what part I should replace first? cleaned the throttle plate. Have not put a fuel pressure gauge on it yet. It seems to me like it's a fuel delivery problem. Has anybody else experienced similar issues?
