Starter Motor Replacement

 

Starter Repair/Replacement

If your car won't start, you may be in need of a starter replacement. Starting problems may be intermittent at first, but eventually, your starter will fail completely, leaving you & your vehicle stranded. If your vehicle fails to start intermittently, we do amp draw testing on the starter to determine if the resistance is high. An amp test shows if the amperage is too high and causes excessive resistance which is a sign that the starter is failing. To avoid having to have your car towed to the nearest auto repair shop, choose a good mechanic and have your starter replaced as soon as it begins to show signs of trouble. There are many possible issues that could cause a "no start", so be sure to get a complete diagnosis from a mechanic that specializes in charging & starting repair to avoid misdiagnosis, or replacing parts unnecessarily.

 

Two Types of Starting Failure

No Crank, No Start

If the vehicle does not start or crank it could be caused by:

  • A charging system problem such as a bad battery.
  • A starting system problem such as the need for a starter replacement.
  • The ignition switch fails to signal the starter to start the engine. In newer cars, the ignition switch sends a signal to the body control module which then sends it to the starter. On vehicles equipped with an anti-theft device the ignition switch sends the signal first to the anti-theft module, then the body control module and finally to the starter.
  • The transmission fails to recognize that the car is in Park or neutral. This can usually be repaired by a minor shifter adjustment. Bushings on the shifters wear out over time but can be adjusted back into position.
  • Engine is locked up

 

Crank & No Start

Broken Camshaft Replacement to Repair No Start

This broken camshaft must be replaced to repair the internal engine damage which caused the vehicle to not start.

 

If the vehicle is cranking but does not start, some possible causes include:

  • No fuel
  • No compression
  • Broken timing belt
  • No injector pulsation
  • Bad ignition coil
  • Bad crankshaft position sensor
  • Bad camshaft position sensor
  • Faulty fuel pressure rollover sensor that tripped and is not sending power to the fuel pump.
  • Faulty ignition rotor
  • Faulty distributor cap
  • Faulty distributor
  • Faulty ignition wires

 

Ignition Coil Replacement

 

Spark plugs require a great deal of electricity to fire. They rely on ignition coils to draw electricity from the battery and store it until a sufficient amount has built up to fire the plugs. These coils eventually wear out and fail, which prevents the cylinders from firing, and can cause the vehicle to not start. Periodically replacing ignition coils provides increased performance and fuel economy, and is a part of regular maintenance.
