Holds fuel pressure at 60 psi untill reaching a higher rpm then drops to 40 psi and stalls out it fluctuates back n
forth. It started at 4000 rpms but now it is around 1800 rpms and getting worse. This happened over a period of 5
days. I'm thinking it is the fuel pump due to the symptoms of a miss fire and a fuel labor nock and lose of power.
Anyone have any ideas?
The fuel pressure drop is the clue. Yes, you either have a blocked fuel line or need a fuel pump.
