Hope someone can help...my 95 k1500 5.7L Auto was running one day..went down the street and it quit..could not get restarted. Replaced fuel pump, fuel lines, O2 sensor, water temp sensor, fuel pressure regulator, distributor, plugs, wires, and fuel filter. Its getting fuel..the injectors pulse when turning over..its getting spark, timing light flashes when turning over. Sounded like I crewed up installing the distributor...pulled the valve cover off and made sure I was on the compression stroke...rechecked wires. With the gas floored, I get a hickup and a sputter once in a while. Any ideas ??
