CRANKS BUT WONT START

2002 Pontiac Grand Am • 156,000 miles

Sometimes my car will run and sometimes it wont it turns over but when I turn the key on no fuel pump I checked the power when it does it and no power to pump if I turn the key on and off till I hear the pump it will run I ran a wire to the pump and the pump ran but still didnt run not the security could this be ignition or cpu I i hit the dash sometimes this works to and it sometimes dies when driving or when I put it in gear no check engine light but the car has a rough idell when in drive stoped but not in park or while driving but I think thats the gas cap please help
