Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and the engine is off.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Fuel System Inspection

Inspect Fuel Lines:
- Visually check all fuel lines for leaks or damage.
- Tighten any loose connections.
Check Fuel Filter:
- If applicable, replace the fuel filter if it’s clogged or dirty.

3. Fuel Pump and Relay Testing

Test Fuel Pump:
- Connect a fuel pressure gauge to the fuel rail.
- Turn the ignition to the "On" position without starting the engine and check the pressure reading. It should be within the manufacturer’s specified range (typically 30-40 PSI).
Test Relay and Fuses:
- Locate the fuel pump relay in the fuse box and swap it with a similar relay to test functionality.
- Inspect the fuel pump fuse and replace it if blown.

4. Fuel Injector Inspection

Remove and Inspect Injectors:
- Remove the fuel rail and inspect the injectors for clogs or leaks.
- Clean or replace injectors as necessary.

5. Reassemble and Test

Reattach all components, ensuring all connections are secure.
Reconnect the negative battery terminal.
Turn the ignition to the "On" position to prime the fuel system, then attempt to start the engine.
