What makes SPN 94 FMI 18 low fuel pressure?
SPN 94 FMI 18, 2 occurrences. KO/EO the lift pump sounds like its struggling, changing tone and speed. I’m guessing the lift pump is on its last legs but I’m open to suggestions. I plan on checking condition of the wiring and plugs at the same time I change the pump. Every month 400 people find a job with the help of TruckersReport.
What is the SPN code for the fuel filter?
SPN Code: SPN Name: SPN Description: 16: Engine Fuel Filter Differential Pressure (see also SPN 1382) Differential pressure measured across the fuel filter located between the fuel tank and the supply pump. See SPN 1382 and Figures SPN16_A & SPN16_B. 18: Engine Fuel Pressure (Extended Range) 19: Engine Oil Pressure (Extended Range) 20

What’s the fuel pressure on an ISX SPN 94?
Pressure tested the fuel system then put a vacuum on it just to be sure. Passed both tests. The lift pump failed hard. Unstable pressure readings jumping between 8 and 15 psi when KOEO. Replaced the pump and holds a steady 15.2 psi.
How to check fuel delivery pressure on parsianind?
7 Check the feed pump. The sensor is an active sensor, i.e. the sensor must receive operating voltage. Pin 17 on the engine control unit (EMS2) connector B provides pin 1 on the sensor with an operating voltage of +5 Volt. Pin 4 on the sen- sor is connected to battery negative via pin 18 on the EMS2.
What does fault code p3754 mean on PACCAR mx13?
P3754 = Exhaust gas temperature before DPF – Voltage too low or short circuit to ground P3755 = Exhaust gas temperature before DPF – Data erratic, intermittent, or incorrect, not changing during operation
