ANY IDEAS ANYONE? I have a 2006 3500 5.9L diesel. My "wait to start light" comes on while cruising on the highway, but NOT on in town driving. No power loss, smoke or any other issue other than the dash light and that annoying ding. Comes on, goes off, comes back on. The vale cover gasket and ECM was just replaced at dealer. Light is never on when I go back to dealer. New injectors about 50,000 miles ago. Pretty stock except exhaust. 245,000 miles.Thanks

 

There are codes stored, delaer can get them. That is a DTC for excessive fuel leakage in the fuel system. If you had NEW put in ther eis a problem somewhere. If they were dealer remans they are junk.
