My wait to start light comes on while driving, chimes a couple times, stays on for about a minute then goes off. will do those multiple times well im driving, very annoying but doesnt effect anything on my vehicle. i havent noticed it in the city, just hwy driving. i also read an unknown error code on my edge juice that i believe is connected to it, it is P1223. this is becoming a more frequent pop up then before. any ideas? thanks.

my truck is a 2005 cummins w/ fully built tranny, bd cp3, silver 66 turbo, bd 90hp injectors, fass system, gauges, edge juice with hot unlock, all mods done with in the last 2 years.

 

You have a fuel system failure going on of some type.

P1223 - LEAK DETECTION BASED ON QUANTITY BALANCE

Could be injectors FCA or PRV. lots of options. Has the truck been flashed by the dealer lately?
