Engine Mechanical problem
1993 Chevy Citation V8 Four Wheel Drive Automatic 250000 miles
sometimes the pickup does not start, other times it starts really good. I replaced the fuel pump twice and the strainer also. When it does not start, there is no fuel going into the trottle body. I also replaced the fuel filter. The engine turns over really good. Do the injectors get plugged up periodically or could it be the fuel injector pressure regulator? I also checked the fuel pump fuse, and put in a fuel pump relay. Help!
