I was driving my truck and it started runing lean and idling high and acted like it was runing out of fuel then it died I thought the fuel pump went out so I changed it, so now I have fuel and spark but it don't run, the tps tested good and the mass air flow tested fine, no check engine light, need help please.

 

How do you know it was running lean when it died? I guess just start off with the more simple obvious things. I would probably check the plugs, wires, rotor, fuel filter, maybe injectors, that type of thing. If you havent checked out the fuel filter yet, i would look into replacing that. Maybe you sucked up something and it clogged it up...
Just a thought
