One way to fix this is to have the battery charged at a mechanic shop, or auto parts store, or to idle your vehicle after a jumpstart.

• If everything looks good there, move on to checking the fuses.
• If the fuses are all good, then it’s time to check the voltage output of the new alternator. Most alternators have an external voltage regulator that can be adjusted. If the voltage output is too low, it can prevent the car from starting.

How to Troubleshoot Starting Problems – 3 Troubleshooting Ways

If your car won’t start, it’s usually due to one of three things: the battery, the starter, or the fuel system. You can troubleshoot each of these problems in a few different ways.

• If the problem is with the battery, you’ll want to check the connections and make sure they’re clean and tight. You can also test the battery with a voltmeter to see if it’s receiving power. If it’s not, you’ll need to replace it.
• If the problem is with the starter, you can test it by disconnecting the battery and connecting a jumper cable from the positive terminal to the starter terminal. If the starter turns over, you know it’s working and the problem is elsewhere.
• If the problem is with the fuel system, you’ll want to check the fuel pump and make sure it’s getting power. You can also check for leaks in fuel lines or injectors.

When to Call a Tow Truck or Mechanic?

If your car won’t start, you may need to call a tow truck or mechanic. But how do you know when it’s time to call for help? Here are some signs that it’s time to call a tow truck or mechanic:

• You hear a clicking sound when you turn the key. This could be a sign that your battery is dead or that your starter is going bad.
• The engine cranks but doesn’t start. This could be due to a fuel issue, such as a clogged fuel filter, bad fuel pump, or empty gas tank. It could also be due to an ignition issue, such as a bad spark plug or coil.
• The engine starts but stalls. This could be caused by a number of issues, such as a dirty air filter, faulty sensor, dirty throttle body, or low oil level.
• The check engine light is on. This could indicate a serious problem with your engines, such as a misfire or head gasket leak. If the light is blinking, it could be an indication of an even more serious problem that requires immediate attention.
