Modern Toyota MR-Ss rely greatly on electronics, which can mean there are lots of things that can potentially go wrong. Even in an older car, you can still have fairly normal problems such as blown fuses, spark plug problems, a broken ignition switch, or a faulty sensor, and more.

Solutions & Repair Tips

How to Troubleshoot and Fix Battery Issues in a Toyota MR-S

If it’s a battery issue you suspect is the problem, then the first thing you must do is inspect around the battery and check the battery terminals. You want them to be clean, not corroded, and securely connected. If you find that the terminals are corroded you can try to clean them up with a mix of baking soda and water. You will need to replace the battery if it's old or weak, otherwise, even if you charge it up enough to start the car, it will likely deplete quickly again in the near future.

If you can get the vehicle to start up temporarily (you may need to jump-start the car for that), but when it’s going, let the car run, and while it's running, disconnect the positive terminal of your car's battery. It's likely the result of an issue with your car's alternator if you find your Toyota MR-S dies fairly quickly when you disconnect the positive terminal. However, be warned this test can be dangerous if you don't know what you're doing, and may harm the sensitive electronic parts in your car, so in this case best to chat with a professional mechanic local to you or online, before ever attempting this.

How to Identify Starter Motor Failures in a Toyota MR-S

If you suspect the starter motor is the reason for your Toyota MR-S not being able to fire up, listen for a clicking noise when you turn the key in the ignition. In these cases, the solution is to have the starter motor replaced by a professional mechanic.

How to Solve Fuel System Complications in a Toyota MR-S

If you suspect the issue to be due to a fuel system problem, try and listen for the fuel pump when you turn the key to the “on” position, before starting up the vehicle. You ought to hear a humming noise for a couple of seconds. It may be there is a problem with the fuel pump if you are not able to hear this sound. If you discover your Toyota is hard to start, it stalls, or it has poor acceleration, it could be down to a clogged fuel filter. Both of these will likely need a professional car mechanic in order to properly fix.

How to Fix Electrical or Wiring Problems in a Toyota MR-S

If you suspect it's a circuitry or electrical system issue, initially check the fuses related to the ignition system, and change any that have actually blown. If your MR-S starts after this, then it was a successful, inexpensive and simple fix!

If various warning lights are visible on your dashboard, it could be a problematic sensor.

Preventive Steps

As my father always stated “Prevention is better than cure”, so here are some preventative measures to ensure you hopefully avoid any Toyota MR-S starting difficulties again!

Try your best to drive your vehicle regularly to keep the battery charged. If you remember you have not driven your vehicle in a while, take it for a spin to make certain there is still charge in the battery.
