PowerSToKed Posted July 14, 2009 Share Posted July 14, 2009 Had a 99 F-550 dragged in the other day - No start, ICP codes, checked no start pids - found low icp causing no start - found high pressure resevior empty - topped off resevior, after three or four tries truck started. Shut it off after about 30 min and would not restart, icp would only build about 130 psi (icp voltage koeo - .21v), checked resevoir - still full. HP resevoir drains overnight, truck has a new HP oil pump, IPR valve and ICP sensor. I am pretty sure I have an HP oil leak do to it starting cold and no start hot even when the resevoir is full but I do not understand what is causing the HP resevoir to drain overnight Quote Link to comment Share on other sites More sharing options...
sixturbosix Posted July 14, 2009 Share Posted July 14, 2009 Have you looked to see if the check ball is clean and seating correctly in bottom of resevoir.Seems like some issues you might look for is oil draining through injectors.Low pressure pump issues.
