Fuel Injectors

  1. Remove injectors but leave hoses connected. Place injectors in individual measuring containers. With sensor plate in idle position, connect jumper wire in place of fuel pump relay.
  2. Disconnect fuel pump when measuring container with highest level of fuel reaches specified capacity. See FUEL INJECTION QUANTITY  table.
  3. Compare amounts of fuel in measuring containers. Fuel quantity should not vary outside specified range. Repeat test with sensor plate in full throttle position.
