Question about Pontiac Trans Sport
Your concern "cranks but will not start", most probable reason is there is no spark, no ignition. The "we smelled fuel" indicates that the engine is getting fuel but is not being burned. Areas to check would be the ignition system then which includes;
Other areas that might have to be checked would be your alarm, security or immobilizer.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.

Your problem loo like A Crankshaft or Camshaft sensor.
Your car use 2 crank sensors. on a 3.4 L. engine.
1 in the front cranshaft pulley. the other right side of the engine or BANK 1 on the engine block
or Missfiring at ramdom Cylinders.
The first step That I can recomend. Is: Check if the vehicle was not OVERHEATED. Because a overheated engine can give this problem. Noise and Rought idle.
But check for any Vacuum leak on the intake manifold. and throttle body. Inspect the the AIR FLOW meter.
The rubber hose going to the throttle body. the PCV. in the front Valve cover. and all the hoses.
But The best STEP is : get the car Scanned with DIAGNOSTIC COMPUTER. After that you will able to know exacttly what step you need to do to fix. Some Auto parts. they scann the vehicles with no charge for that.
Ok I hope this information help to start diagnostic your vehicle.
