How long does a cel have to be on for the pcm to store a code? My 01 7.3 super duty has a cel that will flash on then off until it is up to operating temperature. I had a friend who wrenches drop by with his scan tool. It shows no codes. I asked if it was set up to pull diesel codes and he said yes. Hence my question. It’s started to have a long crank to start, weather cold or fully up to temp. Is he smokin crack and his tool isn’t setup to pull codes on my truck?
