Fuel Pump Compatible For Isuzu 4JA1 104741-6390 104641-6390 8943616790 9460613371 Engine Replacement Parts
DENGUSYO Fuel Pump Compatible For Isuzu 4JA1 104741-6390 104641-6390 8943616790 9460613371 Engine Replacement Parts || Stable pressure Can provide stable fuel pressure, ensuring precise injection of fuel into the engine cylinder. For example, under different working conditions of the car (such as idle, acceleration, climbing, etc.), the fuel pump can supply fuel at an appropriate pressure, allowing the engine to burn more fully and the power output to be more stable. || Efficient fuel delivery The fuel pump operates efficiently and can quickly deliver fuel from the tank to the engine. Like a powerful 'small water pump', it can timely meet the engine's fuel demand and ensure the continuous and stable operation of the engine. || Good durability Usually made of good materials and advanced manufacturing processes, it can withstand the corrosion of fuel and wear during long-term operation. This means that it can work stably throughout the entire life cycle of the car, reducing the frequency of maintenance and replacement. || Energy saving: Some advanced fuel pumps can intelligently adjust the fuel delivery amount according to the actual needs of the engine, avoiding fuel waste and helping to improve the fuel economy of cars.

Handle the parts in accordance with yourWarranty Bulletin on warranty parts handling.
Attach. (1-Rework Procedure)Rework Procedure
The two tests below provide the appropriateinjector troubleshooting and repair steps for injector updates.
Use "Test for Cylinder Cutout" to determine ifindividual injector replacements (using original injector part) are needed.
Use "Test for Leakage from Poppet Valve" to determineif full injector sets (using new injector parts and software change) areappropriate for repair.
Test for Cylinder Cutout:
Warm the engine out of Cold Mode.
Connect Caterpillar Electronic Technician (ET)to the engine while the engine is running.
Ensure that the engine speed is 1200 rpm +/- 125rpm. An extremely rough running engine well need to be diagnosed by othermethods.
Cut out one bank of cylinders. Note engine rpmand the fuel position on the ET screen at that time.
Cut out one of the remaining cylinders from thecylinder bank that is running. Allow the engine to stabilize and note thefuel position.
Give power back to that cylinder. Allow the engineto stabilize and note the fuel position.
Repeat steps 5 through 6 until the cylinder bankhas been completely checked.
Power all cylinders. Allow the engine to stabilize.
Cut out the other cylinder bank and repeat steps5 through 8.
Repeat steps 4 through 9 with the engine at 2000rpm.
Compare the results from the fuel position fromeach cylinder.
If the cylinder was cut out and the fuel positiondid not change, the cylinder may not have producing power. This cylinderwould be suspect.
When you are finished with the test, decreaseengine rpm to low idle and shut the engine off.
Replace any suspect injector with a similar originalinjector. Install new seals for the injector and the jumper tube duringthis repair. The injector repair procedure is found in Special InstructionREHS0116.
If this is the third injector failure,related to this Service Letter, and to the same engine serial number within120 calendar days, replace all the injectors and software following SpecialInstruction article REHS1385.It is also possible that multiple injectors arefunctioning improperly. Complete "Test for Leakage from Poppet Valve" inorder to evaluate potential excessive injector leakage and need for fuelsystem conversion.Test for Leakage from PoppetValve:
Warm engine out of Cold Mode to normal operatingtemperature.
Turn off the engine.
Remove the valve cover bolts in preparation toobserve the injectors. Leave covers in place.
: Hot oil and components can causepersonal injury. Do not allow hot oil or components to contact skin.
Restart the engine and run at low idle with noload.
Use the ET service tool in order to perform theoverride test for the injection actuation system. Increase injection actuationpressure to the maximum value.
Observe all of the injectors under each valvecover for leakage at the spill port. A small amount of dripping is acceptable.However, a continuous stream of oil is an indication of excessive leakageof the poppet valve. Only leaks at the spill port
