2024 Jeep Gladiator Nighthawk, Part Time T/Case Control, Automatic TransSECTION Technical Data-Fuel System Pressure Specifications
The table below shows the fuel system pressure specifications.
| VARIABLE FUEL PRESSURE SYSTEM SPECIFICATIONS (6.2L ENGINES) | ||
| CRANKING | 520 kPa (75.4 psi) | System operates in open loop during cranking. |
| IDLE | 340 - 400 kPa (49 - 58 psi) | Normal operating range at idle - Pressure is dependant on ambient and fuel temp. Pressure is raised during high temp to prevent boiling. |
| NORMAL RANGE OF OPERATION | 340 - 550 kPa (49 - 80 psi) | Normal operating range between idle and high engine demand. |
| 100% DUTY CYCLE | 600 - 700 kPa (87 - 101.5 psi) | This is regulated by the pressure relief valve in the Fuel Pump. The pressure can vary from pump to pump. |
| 4 CYLINDER (1.0L/1.3L GSET / 2.0L GMET ENGINES) | ||
| CRANKING | 580 kPa (84.1 psi) | System operates in open loop during cranking. |
| ALL OTHER OPERATING CONDITIONS | 520 kPa (75.4 psi) | The fixed pressure systems should maintain approximately 75.0 psi during normal operation. |
| 6 CYLINDER (3.0L GMET ENGINES) | ||
| CRANKING | 650 - 660 kPa (94.2 - 95.7psi) | System operates in open loop during cranking |
| ALL OTHER OPERATING CONDITIONS | 600 kPa (87 psi) | The fixed pressure systems should maintain approximately 87 psi during normal operation. Periodically, with the engine @ idle, the pressure is bumped up to 650 - 660 kPa (94.2 - 95.7psi) to check for a stuck fuel rail pressure sensor signal. |
| FIXED PRESSURE SYSTEM SPECIFICATIONS (ALL OTHER ENGINES) | ||
| The fixed pressure systems should maintain approximately 400 kPa (58.0) psi during normal operation | ||

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
