cycle the key from lock to on position with out starting for about fifty times and run engine for about five minutes and see if it goes off.

Anyone correct me if I am wrong but if u some how got a bad batch of fuel I believe the 'Check Engine Light' will come on w/o throwing any trouble codes. If thats the case. Drain the fuel and change fuel filter. If that is indeed the case, stay away from gas-stations that do not sell much diesel and only have 1 diesel pump and start getting them from truck-stops where the fuel is constantly being used and is fresh!

Pretty sure if its throwing a CEL then there is an issue.....that or your CEL is screwed up......

Need to get ahold of a better scanner. Need to score a tech 2, efi live or something like that.

Were are you located exactly? Can probably find a member that would be willing to help you out.
