a 3.8 has a timing chain not a belt
That's true, it's a simple in-block cam design with two gears and a chain. If there are no drive-ability concerns and the vehicle starts and runs normally there's really no need to check the chain. If you're thinking the chain has stretched or has jumped a tooth you'll need to disassemble the engine and inspect the timing marks. It's worth the 15 bucks to invest in a Haynes or Chilton repair manual for the whole procedure, especially if you haven't done this before.
If the engine won't start at all simply remove the oil cap and the little extension neck if this engine has one and watch the rocker arm while someone cranks the car over. If the chain is connected at all the rocker arm should move.
