it could be anything from a clogged fuel filter to a blocked fuel pump, or losing spark in the distributor cap. if your Pontiac has the PASSLOCK security system in it. turn ignition to on position... but do not start... for (10) ten full min. then turn key OFF for (10) ten more FULL mins. then try to start your car. if this works... REPLACE BATTERY IN KEYFOB (keyless entry keychain device) It may sound crazy but it will work.

1997 Pontiac sunfire wont start has spark and fuel what could be the problem?

Not trying to be funny! It could be almost anything! If you have an Auto Zone any place around you. See if you can get it their somehow and the will run a diagnostic scan at no charge. That should at least get you headed in the right direction. If you have spark, fuel, and air, and it will not start, the timing is off. ==Additionaly,== the other factor in this formula is compression. In order for the car to fire, you need all of the above + compression. If your head gasket has gone south, that can contribute to your problem.

97 Pontiac sunfire 2.4L twin cam will not start it has been sitting still and not started for over a year while I was in Iraq Has a new battery but will not turn over. Has a half tank of gas in it?

I think there's a communication problem here. Turning over doesn't have anything to do with gas. Grab another car that runs. Disconnect the sparkplug wires and try to start it. That a "Cranks- no start". Now reconnect the wires. Remove the key and put it in your pocket. Try to start the car. The sound of a "no-start no-crank." Which is your sunfire sounding more like?
