Car is shutting off when i put it in reverse.if i do manage to get it on the road it will shut off when i either stopped at a red light or if i put it into park. Also misfiring and no get up with the acceleration. ive changed my fuel filters, air filter, vacuum lines, pcv, sparkplugs , sparkplug wires, rotor button, dis.cap, new catalytic converter and exaust pipe.now im just exausted my damn self.lol would these all be causes of the fuel pump, or is it something else?

 

Have you cleaned the carb (almost forgot 84 has carb)? Or reset the minimum idle speed?
