I have a 1990 chevy truck have replaced all sensors on engine, plugs, wires, cap, rotor, igniition module, and pickup coil all within the last 2 weeks. Has been running great since, until yesterday and it turns over strong but suddenly I have fuel to the TBI but none to the injectors. Also I have power to the coil but no spark. Could this possibly be the E.C.M-powertrain control module? Any Ideas thanks
