Engine failure: The mechanical reasons why your car won’t start

It’s one of the worst feelings that a driver will experience. The moment when you turn the ignition only to feel the engine crank and not respond is something that’s often met with dread and later down the line, incredible expense.

Of course, there are umpteen reasons behind this. On a lot of occasions it might be nothing related directly to the engine – it might be something like poor electrical connections and it’s in these cases where a service contract, from the likes of Omega Auto Care, will see you over the line.

Unfortunately, it’s not always that simple. There will be occasions where the problem is directly linked to your engine and this can be when the costs start racking up. We’ll now take a look at some of the reasons why this problem occurs and what you might have to do to resolve it.

One of the best-case scenarios: you’ve run out of fuel

Let’s start with the least-serious solution; the one that’s probably going to prompt plenty of laughs from many of your friends. It will probably happen to everyone at least once in their lifetime but if you have run out of gas, your engine will react just like it would if you had suffered a mechanical breakdown. There’s no fuel to burn and the engine will crank, but ultimately, it’s a very simple issue to resolve.

Your fuel pump is broken

Staying on the topic of fuel, this one is a little more serious and will probably require a new part.

While your tank might be full, if the part which pumps the solution to your engine is defective then things just aren’t going to run.

There are many reasons why a fuel pump will falter, although one of the most common ones is that the car has been run on an empty tank for too long. In a bid to quickly diagnose the problem, you can turn to a fuel pressure gauge which will quickly tell you whether your engine is receiving adequate amounts of fuel.

A clogged fuel system

Once again, this next reason is related to the fuel system. It’s not the most serious engine-failure problem you can have, but it’s one that can still make you sweat when it does occur.

If any debris has found its way into your fuel, this is a problem which is very likely to happen. Again, it can prevent adequate amounts of fuel passing through.

It’s worth mentioning that this problem typically won’t affect newer cars, as fuel filters only tend to fail once the car has surpassed the 100,000 mile mark.

The starter has gone

Something else which can cause the dreaded engine failure is when the starter has gone.

We’re not going to start branding around possible costs here; the fact that a starter could cover the bearings, bushing and gears means it’s something of a wide issue.

If you notice that your headlights start to dim when you try and turn the ignition, when they were previously bright, there’s a good chance that you need to invest in a new starter.
