| 03 chevy 1500 i hope this helps some ppl. i have a 03 chevy 1500 with 4.3L and it stopped running. no spark to the plugs, so like every shade tree mach. i replaced the ing. pickup stator, ing. control mod., coil, plugs, and wires, crank postion sencer and still nothing. i ran through all the fuzes and relays, they were all good, so i got a book on my truck and went through the long process of checking everything and the book said if everything is good then check the pcm (powertrain control mod.) so i got tired of messing with it and took it to the dealer and ran the diagnostic and it came back as misfire codes crank shaft postion codes and no spark to coil and a open harness to coil with i dont understand because i never have touched the coil before this. and they had to update my pcm with the latest engine and trans calibrations. the dealer charged me $250.00 to have that done. not including the $250.00 i spent to replace everything else. |
