If you know you have spark, try spraying a little starting fluid into the intake and see if it starts momentarily. If not, then you need to do a complete compression test. Also check the plugs to see if they are fouled at all.

Did you use a gage to check fuel pressure? Use a noid lite check for injector pulse. Any applicable mil codes? You can check those, yourself. Do you have good compression?

Also, you could try some starter fluid in the throttle-body, not too much, see if it will start. There are safety issues with flammable spray. Safety is your responsibility. I usually take the air duct loose from throttle body, open throttle valve, spray a little, stand back from the vehicle, have helper crank it.

Fuel Pressure is at 50 psi. Tried the starting fluid still wont start. I am getting flame when tried with starting fluid. Also there is gas in the air cleaner that ignites also.

If everything you have said so far is true and accurate, then you will find a problem with compression. If you find no problem with the compression, then you need to go back the square one and start over with your testing because something is wrong with previous testing.
