Are you saying the engine will not crank ? If yes, will it crank with a boost from another battery ? The battery or cables could be too weak to handle the power draw from the starter.

SOURCE: 2001 Pontiac Sunfire Fuel Problem

Are you certain that the engine is getting fuel? If not, then you will have to verify that there isn't any blockage in the fuel system to prevent the fuel from reaching the engine. If fuel is reaching the engine, try the following
1. Check compression values for each cylinder.

2. Inspect electrical circuitry in the distributor assembly (slack wires, broken wires, dmaged rotor etc)

3. Check to see if the timing belt was not severed. This belt transmits the drive from the crankshaft to the camshaft. If the belt ius severed, the camshaft cannot rotate in order to open the valves

SOURCE: 2003 sunfire won't start fuel pump cuts in sometimes

There is no fuel cut off switch on this vehicle. Check for fuel and spark. And let me know.

It sounds like you have a security problem, I had the same thing it would fire and run for half of a second and then that was it if anything at all. Had the security system rebooted, now it starts and runs fine.

My 02 sunfire died on me all of a sudden and now wont start but will turn over i have checked the fuses and they seem to be ok


This may sound really dumb, but check your fuel... The 00 to 02 Sunfires had a problem with the fuelguage reading inacurately. Sometimes by as much as 1/3 of a tank. If not that then start at the basics, look for fuel getting to the engine, and spark... If the fuel pump is the culprit you can try having a partner hit the fuel tank with a rubber, or NON METAL hammer while your cranking the engine. If the car starts then dont risk it not starting again, get the fuel pump replaced right away.
