05 runing rough open circuit on #2 injector

pinto7579 · 06-13-2010, 11:32 PM

when it started it would fade in and out. leading me to believe it was a wire. i found no bad wires but it cleared the code and would not run. got it back in the shop today primed the fuel system and it will run still showing open circuit on #2 injector any ideas

pinto7579 · 06-14-2010, 03:26 AM

i cant believe that a injector would be bad . because if a injector fails it fails which lead me to believe that it was a wire. but it could be in the computer. any help is appreciated

pinto7579 · 06-15-2010, 03:12 AM
