another thing that people tend to forget is the rotation of the dist. if that is in the wrong direction it would cause the same problems it should be counter clock wise. and the way the pistons are numbered could have something to do with it as well

you might try this simple test to see if the gas is good enough to run the engine, take a little gas out of the tank or lines and pour it into a glass jar or on the ground and strike a match to see if the gas will burn. and you should almost always buy new injectors if you're gonna replace them it doesn't take very long for injectors to clog up and not work
