A fuel pressure tester has a gauge or dial that shows the fuel coercion in a vehicle.
The Dodge 3.9-liter V-6 was introduced in 1987 for the 1988 replica year. The 3.9-liter Dodge engine was solitary used in the Dakota, the 1500 Ram, and the 1500 Ram automobile. The 1996 Dodge 3.9-liter engine was equipped with multiple end or "multi-point" fuel injection.3. Install a fuel pressure tester onto the fuel pressure testing port. Fasten the tester fitting onto the port by turning it clockwise by hand.
Instructions
1. Elevate the hood on the vehicle on which you are performing the fuel power research. Locate the hood prop to clasp the hood during this project, provided one is available.
2. Visually peep and place the fuel lambaste on the Chauffeur's side of the 3.9-liter engine. Allot the impact testing port on the fuel inveigh. The tester Harbour has a cap on it that is corresponding to a tire valve stem cap. Remove the energy tester protective cap by turning it counterclockwise with your ability.
The injectors are on the sides of the engine above Everyone combustion Hospital ward or cylinder. The injectors are fed with fuel by the fuel rail, which is a metal lambaste that encircles the top of the engine. The fuel against has a fuel energy testing Harbour built into the inveigh itself. Ask an assistant or second person to turn the engine of the vehicle on, while you hold the pressure tester gauge away from the engine. If the engine does not start, ask your assistant to turn the ignition key so that the engine turns over. Instruct your assistant not to turn the key for longer than 3 second intervals, as you will destroy the engine starter by doing so.
4. Read the dial gauge on the pressure tester to see how much fuel pressure the 3.9-liter is putting out. The gauge should be between 44 and 54 p.s.i. or pounds per square inch. If the engine is running and the number on the gauge is outside of the given parameters, then there is an issue with the fuel pressure in the engine.
