no fuel on two cylinders

[Vancho]

Ok so i did a few things to my 1998 Gst, rebuilt the engine, started it, ran fine for about 50 miles, i changed out the fuel filter because the car has been sitting for over a year before i touched it. haven't poured more fuel in it yet, and after i changed out the fuel filter, it ran for about ten miles, i parked it. Then went to start it and it wouldn't start. I took out the sparks and two were soaked in fuel, and two were dry, i got a different set of injectors, same thing cylinder one and two were wet, 3 and 4 were dry, i put the injectors that were just spraying in the first two cylinders, to the last two, and they still don't spray, so i understand that i get fuel to the rail, i get fuel to the first two cylinders, but i don't understand why the 3rd and 4th cylinder don't spray, and when i drove it for the first 50 miles, i barley gave it gas, and the headers and exhaust part of the turbo were glowing red after about 10 miles of driving it, to which makes me think i run lean. full power wasn't there, it drove but just didn't seem right, if someone knows anything that i can do or check let me know please, thanks

Ok so i learned something, do a compression check before i start checking everything else, ends up i had 8 bent exhaust valves, but i still dont understand how it ran for 50 miles and just dies and cannot be started, but anyway thanks for the help guys!
