How do you know fuel is sprayed from injectors if spark pugs aren't wet? Several starting attempts without the engine ever firing up should result in either a flooded engine or at the least, wet plugs. Try this first; hold throttle wide open (this tells the ecm via the throttle position sensor) to halt injector operation on a cold engine while you crank the engine over. If the engine flooded, this will blow out remaining fuel and help dry off (shorted) plugs. Crank for about 5 seconds then stop. Release gas pedal and try starting again (do not pump the gas pedal as this doesn't work on EFI engines with injectors). If this fails to get the engine to startup, try the next suggestion to test for spark.
Spray starting fluid into the throttle body and startup. If spark occurs, the engine should fire up. If startup doesn't occur, the ignition system may be faulty because you're spraying fuel into the throttle body.
