1. Fuel Supply:
* Fuel tank: Is the tank actually full? Sounds obvious, but it's the first thing to check. Is there a blockage in the fuel line leading from the tank? Check for kinks, rust, or debris.
* Fuel filter: A clogged fuel filter is a very common cause. Replace it. Even a new pump can't overcome a blocked filter.
* Fuel line connection: Check *all* fuel line connections for leaks and ensure they're securely attached. A loose connection will prevent fuel from reaching the pump.
2. Fuel Pump Priming (if applicable):
* Some older fuel pumps require priming. See your owner's manual or a repair manual for your specific model. This might involve manually pumping a lever on the pump or using a priming tool.
3. Fuel Pump Wiring and Power:
* Wiring connections: Carefully inspect the wiring to the fuel pump. Are the connections clean and secure? Corrosion can prevent power from reaching the pump.
* Fuse: Check the fuse that powers the fuel pump (if applicable). A blown fuse will stop the pump from working. If it's blown, check for a short circuit before replacing it.
* Relay (if applicable): Some cars use a relay to control the fuel pump. A faulty relay will prevent the pump from receiving power. Test the relay with a multimeter.
* Power at the pump: Use a multimeter to check for power at the fuel pump connector. You should have power when the ignition is turned on.
4. Engine-Related Issues (Less Likely):
* Fuel pressure regulator: A faulty fuel pressure regulator *could* prevent sufficient fuel pressure, but you'd probably have other symptoms before a new pump installation.
* Clogged fuel injectors (if fuel-injected): If your '67 Camaro has fuel injection (unlikely), clogged injectors could prevent fuel from reaching the engine, but the pump should still operate. A carburetor-equipped car won't have this issue.
5. Fuel Pump Installation:
* Grounding: Make absolutely certain the pump is properly grounded. A poor ground can prevent it from working.
* Pump direction: Ensure that the fuel pump is installed correctly, paying attention to the direction of flow. A reversed pump will not function properly.
Troubleshooting Steps:
1. Start with the easiest: Check the fuel tank level, the fuel filter, and all connections.
2. Check for power: Verify that power is reaching the fuel pump.
3. Use a pressure gauge (if possible): If you have access to a fuel pressure gauge, connect it to check the fuel pressure. This will tell you if the pump is actually pumping fuel.
If you've checked all of these and the problem persists, it's time to consult a mechanic. They have specialized tools and knowledge to diagnose more complex issues. Remember safety first—work on a well-ventilated area and avoid sparks near fuel.
