how to fix a Honda Accord that won't start with a new battery

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect Battery Connections

• Tools Required: Socket set, wire brush, safety gloves
• Remove the battery terminals (negative first, then positive).
• Clean the terminals and battery posts with a wire brush to remove any corrosion.
• Reconnect the terminals securely (positive first, then negative).

3. Check and Replace Fuses

• Tools Required: Fuse puller or pliers
• Locate the fuse box (refer to the owner's manual for location).
• Inspect fuses related to the ignition and starter; replace any that are blown with fuses of the same amperage.

4. Test the Starter Motor

• Tools Required: Multimeter, socket set
• Locate the starter motor (typically found near the transmission).
• Use the multimeter to check for voltage at the starter terminal while a helper turns the key to the start position.
• If voltage is present and the starter does not engage, replace the starter motor.

5. Check the Fuel Pump

• Tools Required: Fuel pressure gauge
• Locate the fuel pump relay and ensure it is functioning.
• Connect the fuel pressure gauge to the fuel rail to measure pressure while attempting to start the engine.
• If pressure is low or absent, consider replacing the fuel pump.
