However, if you're determined to do it yourself, here's a general outline. Remember this is a general guide, and specifics might vary slightly depending on your exact engine and van configuration. Always consult a repair manual specific to your 1993 Pontiac Transport for detailed instructions and diagrams.
Safety First!
* Disconnect the negative battery terminal before starting any work.
* Work in a well-ventilated area. Gasoline fumes are extremely flammable and dangerous.
* Wear safety glasses and gloves.
* Have a fire extinguisher readily available.
* Use proper jack stands to safely support the vehicle. Never work under a vehicle supported only by a jack.
* Understand the location of your fuel pump. It's usually located within the fuel tank, requiring tank removal or dropping the tank.
General Steps (Consult your repair manual for precise details):
1. Prepare the Vehicle: Jack up the van securely and support it with jack stands. Locate the fuel tank access panel (usually under the vehicle, possibly near the rear axle). You may need to remove other components to access the tank.
2. Drain the Fuel Tank (Crucial): This is essential to minimize fuel spillage. Use a siphon pump to carefully remove as much fuel as possible from the tank.
3. Disconnect the Fuel Lines: Carefully disconnect the fuel lines leading to the fuel tank. Have rags ready to absorb any spilled fuel. You may need to relieve pressure in the fuel lines. Some vehicles have a quick disconnect, others may require line wrenches.
4. Disconnect the Electrical Connector: Disconnect the electrical connector to the fuel pump.
5. Remove the Fuel Tank (Most Likely): This is often the most challenging step. The tank is usually held in place by straps or bolts. You'll likely need to disconnect the fuel tank sending unit (the part that measures fuel level) as well. Be extremely careful during this process to avoid damaging any fuel lines or the tank itself.
6. Access and Remove the Fuel Pump: Once the tank is lowered or removed, you'll be able to access the fuel pump. It's usually held in place by a retaining ring or bolts. Again, consult your repair manual for specific removal instructions.
7. Install the New Fuel Pump: Install the new fuel pump, making sure it's seated correctly. Follow the manufacturer's instructions that came with the new pump.
8. Reassemble Everything: Carefully reassemble the fuel tank, fuel lines, electrical connector, and any other components you removed. Ensure all connections are secure and tight. Double-check all fuel lines for leaks.
9. Lower the Fuel Tank and Securely Reattach: Lower the tank carefully and secure it back into its position.
10. Reconnect the Battery and Test: Reconnect the negative battery terminal. Try to start the engine to ensure the new pump works correctly. Check for leaks around all fuel connections.
Important Considerations:
* Fuel Pump Replacement Kit: It's recommended to purchase a fuel pump replacement kit, which often includes new fuel filter, seals, and other necessary parts.
* Repair Manual: A repair manual specific to your 1993 Pontiac Transport is invaluable. It provides detailed step-by-step instructions, diagrams, and torque specifications.
* Professional Help: If you encounter any difficulties or feel uncomfortable at any point, stop and seek professional help. This job can be complicated and potentially hazardous if not done correctly.
This is a complex repair; proceed with extreme caution and prioritize your safety. Again, consulting a repair manual and possibly a professional mechanic is highly recommended.
