6.0 Hard start cold 04.5 f-550
Does this sound like classic hpo leak ? Cranks and cranks cold but will only fire with a shot of ether, after running has no problem restarting. Only codes are 2290 and a cam sensor code? But the cam sensor maybe due to excessive cranking?, ficm is 47.5 to 49.5 batt voltages are 13.8 ( both load tested and new) 2290 code been on edge insight for long time before issue started, hpop is approx 3 yrs old, stc fitting new then, dummy plugs both done within last year when injectors replaced. Ipr about 1 yr old same with icp sensor and pigtail. Fresh clean rotella t6 every 5500 miles, all i know that it needs is a new air filter,everything else is fresh.
