Checking fuel injectors with a screwdriver requires the right knowledge and technique. The following steps should be followed:
- Remove any debris or dirt that may be covering the fuel injector.
- Disconnect the negative battery cable from your vehicle's battery to prevent electric shock.
- Locate the fuel injector, then use a screwdriver to unscrew it from its mountings.
- Inspect for signs of damage such as corrosion or clogging, which you can fix if necessary by cleaning or replacing parts.
- Reconnect all components before starting your engine again and test drive to ensure proper function of your vehicle’s fuel system.
