Hi,
I have an F-250 1997 with a 7.3L diesel, and it just died yesterday while driving down the road. I changed the fuel filter and checked the air cleaner (OK). I ended up having it towed back to my shop. This morning I noticed that the "wait to start" light is no longer functioning. Sounds like a possible electrical problem or controller failure. Is there anything else I can do or is it time to take it to a repair shop with a code reader?

thanks,

RS
