My dad has an 04 3500 ctd. Its been a freakin nightmare. 3 sets of injectors, new lp, new engine at 98000, at least it was still under warranty! New engine has 16000 on it now and He drove it home last night and parked it. went out to start it in the morning and it will crank but will not fire. Sounds like no fuel. Tried some ether and still nothing. I havent cracked a line to see for sure if its getting fuel but i can hear the lp running and the ip doesnt make any noise. It has two codes... p0341 p2509. I dont know much about these common rails so any help would b appreciated
