Hey everyone, i recently purchased a 1992 GMC Sonoma 4X4 for cheap and i have to resurrect it. The problem is that it isn't getting gas to the engine. I know it is getting gas to the throttle body injectors but they won't spray. I have replaced the fuel pump, the fuel filter, fuel pump relay, TPS, and both injectors. On occasion it will spit some gas out but not enough to start it. What i am wondering is what tells the injectors to spray gas? is it the ECM? Thanx, as soon as i get this thing running i may become a full CK5 member (even though i don't own a full size).
