If they have been sitting for a while..... they may be stuck. I tried installing my old fbd 100s that were on the shelf for a few years. Started up and ran on 4 or 5 cylinders. Wasted $30 in seals and orings. If the injectors are working in the truck now just replace the seals. Very easy. Do it sooner then later and do a few oil changes to get the diesel out of there

Just went through this on mine. It’s been an ongoing issue for a while in the colder weather after the truck sat overnight. Never and issue when the truck sat at work for longer periods of time. I also had a tapper cover leak that I repaired. Truck was good for 2 weeks...... then....... I replaced: straight cut orings on the t fitting o rings on the return line at the vp44 new return relief valve on vp44 new fuel line and fittings from lift pump forward- 15 psi idle new filters on the fass still hard a hard start that was worsening, noticed fuel in oil. replaced: injector o rings- were VERY flat and came out easy, real easy new crossover o rings seemed to solve the fuel in oil issue then: new #4 injector line- was leaking at head after initial injector o ring change new crossover tubes from BD diesel and orings- figured it’s was best as they had 240k on them and been through 4 injector swaps so far so good! Truck runs a lot better all around. Power is back to where it’s supposed to be. Happy till the next issue arises. I’m 99% positive the injector o rings were my issue. Only time will tell if the oil level rises again, then it’s time to dig a big hole and burry it.
