Medium and Heavy Trucks
Have Truck Repair Questions? Ask an Expert
Hi my name is***** will be glad to try to help. Are there any fault codes? Does the check engine light come on? What do you have for fuel pressure and is it consistent? Did you install a clear hose or sight glass to watch for bubbles on the suction and return lines?
Also check with your scan tool that you are not losing engine RPM signal to the ECM. Replace the oil soaked sensor as it should not be bathed in oil through the connector. Let me know
