Fuel in the coolant of an ISX engine can be caused by a few issues, primarily a failing fuel injector or a cracked fuel rail, which can allow fuel to leak into the coolant system. Additionally, a damaged head gasket could also permit fuel to mix with coolant. These problems can lead to serious engine damage if not addressed promptly, so it's important to diagnose and repair the source of the contamination quickly. Regular maintenance and monitoring can help prevent such issues.

Where is fuel pressure sensor on Cummings isx?
On a Cummins ISX engine, the fuel pressure sensor is typically located on the fuel rail or near the fuel filter assembly. It monitors the fuel pressure in the system to ensure proper fuel delivery to the injectors. Accessing it may require removing some components for better visibility and reach. Always consult the engine's service manual for specific details and location based on your engine model.
Would a coolant sensor cause a rough idle?
Coolant sensors can cause a lot of various problems. The ECM relies on the coolant sensor for temperature readings. This is so that it can adjust the timing, fuel, and other related systems. But without knowing more I couldn't say that it is your problem.
