Hey guys, I've been fighting a few codes on my truck with dual pumps and trying to isolate the problem.
The codes are p0087, p0091,and p2291.
The truck drives normal until rail pressure reaches about 10k then will tank to 1.5-2kpsi.
I repaired some exposed wires for the second pump and changed the rail pressure sensor with no change. There is absolutely no metal in the system.
I'm thinking of temporarily putting it back to a single pump to help narrow down the problem.
Anyone have some ideas of what I could try before I go back to a single pump?
Thanks.
