well on my way early this morning to a pig pickin, my truck left me stranded... it cranked fine this morning, no warning until it quit... was running interstate about 65, it sputtered and smoked like hell for a couple of seconds and then cut off... coasted to the side and tried to restart numerous times but no luck... it will try to crank after about 10 seconds of cranking but just smokes big time and acts like it is on one cylinder and just dies... checked all intercooler connections and they are good, no water in the filter, no fuel smell anywhere... had it towed to the dealer but do not trust them at all... . give me some things to consider... what does a bad lift pump do or anything else that comes to mind... i did change the overflow valve about a month ago and it just never seemed like it cranked as well after that... probably my imagination. . any help is appreciated...
