Keith Browning Posted June 25, 2018 Share Posted June 25, 2018 Ever see this? The engine is knocking hard while cranking with contribution codes for 3,4 and 6. Towed in for no start. I did not expect to see this. Quote Link to comment Share on other sites More sharing options...
tonybullitt Posted June 25, 2018 Share Posted June 25, 2018 No haven't seen that yet. I had a so called diesel performance shop call and ask me how long after replacing the glow plugs does it usually take to get compression to come back up. They replaced glow plugs with new style and it still sets low contribution codes. I didn't know how to respond to that. Quote Link to comment Share on other sites More sharing options...
forddieseldoctor Posted June 25, 2018 Share Posted June 25, 2018 I saw it once, but I can’t remember how I got rid of it. Quote Link to comment Share on other sites More sharing options...
