Here's a general outline of the process. This is not a comprehensive guide and may not cover all variations depending on your specific Rodeo model (2WD vs. 4WD, engine type). Consult a repair manual specific to your 1995 Isuzu Rodeo for detailed instructions and diagrams. Repair manuals like those from Haynes or Chilton are invaluable for this type of work.
1. Preparation:
* Safety First: Disconnect the negative battery cable.
* Gather Tools: You'll need a socket set (various sizes), wrenches, screwdrivers (Phillips and flathead), a fuel pump removal tool (often a special socket or hook), jack stands, jack, safety glasses, gloves, and rags.
* Drain the Fuel Tank: This is highly recommended to minimize the risk of spills and to make the job easier. You can siphon the gas carefully into a suitable container. Never work near open flames or sparks.
* Locate the Fuel Pump: This is usually accessed through the bed of the truck (if a pickup) or under the rear seat in some models (SUV). Consult your repair manual to pinpoint the location.
2. Accessing the Fuel Pump:
* Drop the Fuel Tank (Most Common): This often involves lowering the fuel tank to gain access. This will require disconnecting fuel lines, electrical connectors, and possibly the fuel tank straps. Support the tank safely to avoid damage. Be extremely careful with fuel lines; any damage can lead to leaks.
* Access Panel (Some Models): Some Rodeos may have an access panel under the rear seat or in the bed allowing direct access to the fuel pump without removing the tank.
3. Fuel Pump Removal:
* Disconnect Electrical Connectors: Carefully disconnect the electrical connectors leading to the fuel pump.
* Disconnect Fuel Lines: Disconnect the fuel lines using the appropriate wrenches or line disconnect tools. Have rags ready to absorb any spilled fuel.
* Remove the Fuel Pump: Use the fuel pump removal tool to carefully remove the pump assembly from the tank. This may involve unscrewing or unclipping the pump from its mounting. The pump assembly may also include the fuel level sender.
4. Fuel Pump Installation:
* Install New Fuel Pump: Carefully install the new fuel pump assembly, ensuring it's properly seated and aligned.
* Reconnect Fuel Lines: Carefully reconnect the fuel lines, ensuring a tight and secure connection.
* Reconnect Electrical Connectors: Reconnect the electrical connectors.
* Reinstall Fuel Tank (If Removed): Carefully raise the fuel tank back into place, securing it with the straps.
* Reconnect Battery: Reconnect the negative battery cable.
5. Testing:
* Prime the Fuel System: There may be a priming procedure to ensure the fuel pump is functioning correctly before starting the engine. Refer to your repair manual.
* Start the Engine: Start the engine and listen for any unusual noises from the fuel pump. Check for fuel leaks.
* Check for Proper Fuel Pressure: You might need a fuel pressure gauge to check that the fuel pressure is within the specified range.
Important Considerations:
* Repair Manual: A repair manual specific to your 1995 Isuzu Rodeo is crucial. It will provide detailed instructions, diagrams, torque specifications, and safety precautions.
* Fuel Safety: Gasoline is extremely flammable and potentially explosive. Work in a well-ventilated area, away from any ignition sources.
* Fuel Line Integrity: Damaged fuel lines can cause serious problems. Replace any damaged or deteriorated lines.
* Professional Help: If you are not comfortable performing this repair, take your Rodeo to a qualified mechanic.
