I think has stuck injector at least 2 plugs were wet fouled1 plug had a brown ring around the porclean insulator
 
Be careful with your pre-cat,... you may have already wrecked it. (raw fuel on the pre-cat destroys it quickly)

Here is the procedure for checking the injectors.

The fuel system is covered in the downloadable Factory Service Manual (chapter 14 of the engine section)

I'm more inclined to think you have an ignition problem. Were the two wet spark plugs connected to the same coil ???
 
my thinking is a bad fuel pressure regulator , and sucking fuel in to the intake plenum
 
OK,... I know nothing about that but here's where to test for fuel pressure:

Or even easier - pull the plugs - one that is super clean is being washed in excess gas and will be wet/oily.

Change that injector (or try cleaning it).
 
i check F regulator , pulled plugs , the center 2 cylinders are wet . I swapped in a coil pack .didnt help . here is a pic of the fuel vapor and dripping gas after 1 min of running . still no engine light

I think you should get one of these:

And do this:

That will rule out injectors.

The center two cylinders run off the same coil,... You may have a bad control wire feeding that coil (short or open).

Check for spark from those two cylinders.

If you've got no spark from either spark plug from cylinders 2 and 3 then check for a bad wire at the coil's connector.
