Car Engine Turning over too Fast? Try this

You’ll therefore notice if it is turning over too fast. From experience, there is an expectation of how fast the car engine turns over when you turn on the ignition.

While the car may be able to start and run fine in some cases (sometimes it stalls and dies), it is good to know what might be the problem so that you can fix it as soon as possible, or else you risk getting stuck on the road later.

This post looks at why your car engine may be turning over too fast, and what you may be able to do to get it starting normally again.

Why Your Car May Be Cranking Fast?

If the car engine is cranking too fast, then you might have one of the following problems.

#1. Stuck starter solenoid. If the starter’s pinion teeth stay engaged with the flywheel after the engine has started running, then the starter will run faster than usual.

The pinion teeth are supposed to disengage after the engine has started.

This can happen if you have any of the following situations: you keep the ignition key in the START position after the car has started, the flywheel has damaged teeth, or the starter teeth or flywheel teeth are damaged.

Fix: If it is a faulty starter, replace it. Confirm that the ignition key does not remain in the ON position after the car has started.

Seek the services of a qualified mechanic to inspect the starter and flywheel for any damaged teeth.

#2. The engine has low compression. If the car engine starts but does not generate enough pressure then the car engine will crank faster than usual.

If one or more of the valves, or pistons are damaged then the car engine will not have enough compression.

Have the car inspected by a qualified mechanic. To confirm if it is a case of low compression, the mechanic can conduct a compression test or a leak-down test.

#3. Loosely fitted timing belt. If the timing belt is not firmly fitted on the camshaft and crankshaft gears or is not properly aligned and one or more of the teeth are jumped, then the engine will turn over faster than usual.

A car with a jumped timing belt runs noisily and can shudder too. If the car starts but runs noisily or shudders after starting, get it inspected by a qualified mechanic.

Is it dangerous?

If the car engine is turning over fast, then it is a sign of an underlying problem – poorly aligned timing belt, low compression, or bad starter which if not attended to can result in more damage.

For example, if low compression is not attended to in time, it can result in more damage to the valves.

Therefore, if the car shows signs of turning over too fast, get it inspected by a qualified mechanic.

How fast Should a car Crank?

Normal turning over should be steady, and rhythmical. If on the other hand, it sounds rushed, with increased pace, then you have a case of a car engine turning too fast.

Final Thoughts

If the car engine turns over too fast, then it is possible that the starter solenoid is stuck and remains engaged with the flywheel, the car engine has low compression or the timing belt is loosely fitted and not properly aligned with the camshaft and crankshaft gears.
