If you have tbi fuel system, look to see if injector/s are leaking? Any visible gas leaks under the hood, under the vehicle? Check the pcv system.
Sometimes you can smell gas, undewr the hood, if there is an issue with evap system.
How long since a tune-up? Any applicable mil codes?

You can use a fuel pressure gage. See if pressure will hold for bit, everything off. Check the vacuum line for fuel pressure regulator, any gas in it?
