How many miles on this car?
Combustion requires 3 things - spark, fuel, and compression. When one of these things is not present, or not present in the correct amount, the motor will not run.
An easy way to check for fuel is to turn the motor over a few times, pull a spark plug or two and see if its wet from fuel. If not, you'll have to trace the fuel system back farther, do an injector performance test, check for fuel at the rail, the filter and comming from the pump.
The most painless way to check for spark is to buy a spark tester at your local auto parts store. If there's spark at the plugs, no further diagnosis is necessary. If theres no spark, you'll want to check the outpt of the coil, and test the ignition module for proper performance.
For compression, you'll need a compression tester, though the likelyhood of loosing enough compression in a 2001 vehicle to prevent starting is almost nill.
See if theres spark or fuel at the plugs, and then post back here if you need further help performing the diagnostic checks.
