Welcome to AF!

Did the security light come on when this happened? If so reset the system and it should be fine.

If the security system did not come on make sure that you are getting fuel into the engine through the injectors. Try spraying some starter fluid into the throttle body. If the car starts then you may have an issue with your computer not pulsing the injectors.

it will start for a seconed then back fire and die and shoots smoke out of the intake and some times its hard to roll over im tinking the timeing has jumped or the cam or crank sensor is gone and dont have the money to send it to a garage to get it looked at so i'm stuck wondering
what it might be thats why i come on here to see if anyone has this problem

That sounds like a possibility but there is no cam position sensor on the 3.3. The crank sensor is possible but usually when they go out you won't have good spark so I would certainly check the timing to see what it happening. Good Luck!
