Injector spill valve and pressure leak

[jimeneztrans84]

When I had injector spill valve on my dash it was the fuel pump. I have a cm2250 and had the 3 cylinder pump. Upgraded to the 2 cylinder pump and fuel lines and problem went away. You should have the 2 cilynder pump already since you have a cm2350. My fuel psi would drop when doing fuel rail leak test and couldn't even stay at a steady 29-30 psi while running, it was all over the place. I replaced fuel pump actuator and problem solved. Might want to look at the or fuel pressure check valve in front of the fuel rail. Could be one of those 2 things causing it to loose pressure. Check valve is about $300 and fuel pump actuator $200
