Where does the fuel supply come from in a Cummins ISX15?
1. Fuel supply from tank 2. Fuel supply from retrofit thermal recirculation valve 3. Priming pump 4. Fuel pump gear pump inlet 5. Fuel pump gear pump 6. Fuel pump gear pump outlet 7. ECM cooling plate inlet 8. ECM cooling plate outlet 9. Pressure-side fuel filter inlet 10.
What’s the fuel pressure on a ISX CM2250?
I’m having a fuel issue with a 2010 ISX CM2250 that is driving me crazy. I’m getting a code 559 “Injector Metering Rail Pressure 1”.
What’s the PSI on a Cummins ISX 2250?
If I ease on the throttle and hold it at maybe 50% or less the truck accelerates much better and the measured rail psi is much closer to the commanded psi. I parked the truck and ran the 30 second fuel leak down test and it passed easily. I watched the PSI for over 10 minutes and it actually didn’t drop much at all during that time frame.
Where is the high pressure fuel pump located?
Fuel pump actuator 14. High-pressure fuel pump outlet 15. High-pressure fuel rail supply 16. Fuel rail 17. Fuel pressure sensor location 18. High-pressure relief valve and drain 19. High-pressure injector supply lines 20. High-pressure fuel connector
How did Cummins fix the ISX valve problem?
I read on one of the forums that several years ago Cummins finally admitted the ISX had valve problems. They fixed it by changing the ISX from 650 HP to 600 HP plus some internal changes. Actually they fixed the CM871 EPA 2007 models by redesigning the valves with new, stronger materials, redesigning the head and new programming.
Where does block off plate go on Cummins ISX EGR?
1st block off plate goes on position where EGR manifold meets exhaust manifold. 2nd block off plate goes on position where EGR manifold meets intake manifold. The reason we recommend blocking off EGR on both sides, is because that way engine will run the best.
Where is the EGR valve on ISX CM870?
Click to expand… If you’re talking about an EGR from an ISX CM870, it is not field serviceable. The wire going into the silver cylinder is the stepper motor control, the other plug is the EGR position. If you took it apart, you ruined it since the unit does have to be timed.
When to clear SPN 103-fmi 18 fault code?
For the code to clear, the ratio of boost pressure to ambient pressure must be above 1.19:1 for at least 30 consecutive seconds. This condition can only be achieved during a test drive when the engine is under load.
How big is the fault code on a Cummins?
A certain amount of “drive cycles” may be needed to clear a code from the active status. This has also resulted in a major increase in the number of fault codes present in the Cummins ECM. Codes are becoming more “industry standard” in the numbering method, resulting in the original 3-4 digit Cummins codes having new SPN and FMI numbers attached.
