Was driving home from Wal-Mart this afternoon and the CEL came on while sitting at the stop light. It runs fine and starts up right away. I did have to go through the priming process a few weeks ago for some strange reason, but only once. The truck is stock 1999 3500 except it has a Fass DDRP. It has 217. 336 trouble free miles. Could this be the VP44 and is there any way to check for codes without a scanner.
Thanks
