Hello All,
I have a 2005 Sprinter with 315k. Bought recently and drive/runs well. Previous owner replaced HP pump and all injectors. Started having a p0087 (low fuel rail pressure) code, using a iCarsoft reader. Replaced fuel filter with no improvement of code. Heard a loud noise from under the floor and suspected the in tank pump. Checked fuel pressure after the fuel filter and was getting ~50psi reading. Replaced the in-tank pump and now getting 70psi. Cleared the code and drove some more. The code returned with heavy acceleration, p0087. Did a leak off test and all seem pretty even. No one injector higher than the others. Check the MAF with guidance from Florida Van Man YouTube video and all good there. Drove the van again after clearing the code and continue to get p0087 under hard acceleration. Freeze frame from iCarsoft shows the code happens at 99.2% load, 19,844psi, and 2881 rpm. Last idea is it the fuel rail/sensor. Wanting to hear some opinions before making the purchase of a new fuel rail. They are pricey.
