I did try something else just to check. I disconnect the fuel line where the fuel rail is and placed a small container to see if gas was coming and when I turn the key. When I turned the key, no gas came out. There is no gas going to the fuel rail. Hum..... Fuel Pump?
I'd check the fuel pump I'd most likely pull the line off going into the fuel filter...turn the key to the 'run' position and fuel should spill out of that (could be clogged filter), If you have no fuel going into the fuel filter then I'd verify the fuel pump relay and fuses first then if you have nothing there then I'd check voltage at the fuel pump with the key on if that is ok then yep fuel pump...Good Luck

Easy stuff first ALWAYS
