How To Fix A Slow Cranking Starter

When it comes to starting your car, you want it to start quickly and smoothly. Unfortunately, sometimes our machines can be a bit sluggish—making it difficult to get out of our driveway on cold days. If your car is having trouble cranking over, don’t worry; there are solutions. In this blog post, we will explore some common causes of a slow starter and offer tips on how to fix them. From replacing the battery to cleaning the plugs, we have everything you need to get your car up and running again.

What is a slow cranking starter?

If your car won’t start, the first thing you should do is check your battery. If it’s only weak, try a new one. If that doesn’t work, the problem could be with your starter. Here’s what to do if your car won’t start because of a slow cranking starter:

1) Remove the negative battery cable. If you’re using an automatic transmission, remove the torque converter clutch release solenoid as well.
2) Open the hood and disconnect both engine and transmission mounts from the frame.
3) Remove the starter by loosening the two bolts at either side of its base.
4)Check for broken or dirty screws holding on the flywheel or pulley assembly. Replace any that are found if necessary.
5)Clean and lubricate all moving parts with a bearing grease such as Red Line or Maxima Lube before replacing the flywheel assembly and bolts. Make sure to replace any seals if they have deteriorated. Tighten all bolts to manufacturer specifications and reattach everything in reverse order.

Symptoms of a slow cranking starter

When a car’s engine starts, it usually turns over quickly and efficiently. But if the engine starts slowly, it can be difficult to get it going. There are several possible causes of a slow cranking starter, but the most common is a worn or clogged fuel injector. If the injector isn’t working properly, gas won’t reach the engine’s cylinders in time, causing it to turn over slowly. Other causes of a slow starting car include broken or out-of-warranty spark plugs, blocked air filters, or low oil levels. In most cases, fixing the problem will require replacing one or more parts.

How to fix a slow cranking starter

If your car cranks slowly, there may be a problem with the starter. Follow these steps to fix it:

1. Test the battery. If the battery is good, check for voltage at the starter receptacle. If there’s no voltage, the starter may be bad.

2. Check for continuity at each screw on the motor housing and at each connection point on the stator armature (see diagram below). Continuity means that all of the connections are intact. If any of these connections are poor, you’ll need to replace the motor housing or stator armature.

3. Disconnect everything from the motor and test it using a voltmeter (or an ohmmeter if you have one). If there’s no voltage, replace the battery and connect everything back up.

4. Replace the motor housing or stator armature if one is defective. Repairing these parts can often solve a slow cranking starter problem…


If your car’s starter is taking forever to crank—or if it won’t crank at all—you may need to replace the battery. If you’re not sure how to do this, or if the battery is just old and needs to be replaced anyway, we’ve got a guide on how to fix a slow cranking starter. Hopefully this will get your car up and running again in no time!
