What the hell is wrong with this thing?????
I got a 89 2wd and it only runs on 4 cyl, 3 and 4 are ice cold when you tought the manifold. Ive had the injectors tested, moved them to different cylinders, took the lines off 3 and 4, blew them out with the air hose, and cleaned the delivery valves out. My dad thinks its a burnt valve, and ive heard it could be something in the head of the pump, because before i cleaned the lines it would just puke some fuel out of 3 and 4 when you cracked the injectors loose, now after i blew the lines out they're fine.
So does ANYONE have an idea of what it could be????

a leak down test is a set of guages that you put air into the cyl( piston up both valves closed ) it will tell you if the valves are bad or rings or head gasket it shows a percentage of the air leaking you will hear it in the intake or exhaust if its valves or blowb y tube if its rings and make bubbles in the coolant if head gasket it gives you an idea of where to start looking with out tear down
