I have a 95 7.3 like 6 months ago replaced cps ran good one day died out. replaced fuel pump started running ran 30 mins at idle then it acted like it ran out of gas. Replaced ipr valve and starter as well. Cranking white smoke acts like it wants to start... i replaced fuel bowl harness and got some other un needed draws on the batteries, finally got it to restart again ran and drove about 30-40 mins and again acts like its running out out gas. Any ideas could it be fuel pressure from the spring being worn in the fuel bowl could it be a problem in the tank? If it where the hpop i doubt it would run in the first place..
