I got p0253 Last nite commin home. I've been experiencing surging in the throttle and was trying to hear or notice something about it so i turned the TST to 7 and hit it, when it finally spooled i got the code.


Fuel Injection Pump Fuel Valve Open Circuit Problem

Just curious to what this means exactly.

Well in my book it says "Injection pump metering control A low" Which I am guessing is either an actuator in the vp not functioning properly, or the metering linkages are binding up for some reason or another. ?Just a guess?

Loose plug? Bad actuator?
