Acura RL main relay solder issues causing no start problem on Acura RL

Some Acura RL owners report experiencing no-start problems due to main relay solder issues, which are common in Honda and Acura vehicles, especially in hot weather. Symptoms of a faulty main relay include the starter cranking without the vehicle starting. While main relay failures are often the cause of starting issues, some owners note that the ignition switch can also lead to similar problems. Additionally, engine stall issues in the Acura RL may arise from fuel pump relay failures, further complicating starting issues. To effectively address the solder problems with the main relay, it is advised to properly desolder the connections, as old solder may not flow correctly, and simply adding more solder does not ensure a reliable joint.
