Solution

1. Preparation

Gather necessary tools and parts.
Ensure safety by wearing gloves and goggles.
Disconnect the negative terminal of the battery to avoid electrical issues.

2. Add Fuel

Add 2-3 gallons of fresh fuel to the tank.
Reconnect the negative battery terminal.

3. Prime the Fuel System

Turn the ignition to the "ON" position without starting the engine. This allows the fuel pump to prime the system.
Repeat this step 2-3 times to build up fuel pressure.

4. Check Fuel Pump Functionality

If the engine still won’t start, check the fuel pump fuse and relay.
- Remove the fuse panel cover.
- Locate the fuel pump fuse and relay.
- Replace if blown or faulty.

5. Inspect Fuel Lines

If still no start, check for any visible leaks in the fuel lines.
Inspect all connections and ensure they are tight and secure.

6. Test Fuel Pressure

Use a fuel pressure gauge to check the fuel pressure at the fuel rail.
Compare readings to manufacturer specifications; if low, the fuel pump may need replacement.
