Why won’t my truck start after I turn it off? Answered

Most trucks with starting issues tend to have battery problems – but that’s not the case if your truck takes half an hour to start. In this scenario, you probably have an issue with the ignition coils or the crankshaft position sensor.

Alright, this one is tough. It’s something that you can fix – but I won’t be able to tell you what it is straight away. Instead, I’ll try to guide you to help you figure out what it is.

Vehicle not starting solutions:

  • Faulty ignition coil
  • Crank shaft position sensor
  • Undersized Battery
  • Starter
  • Clogged or dirtyFuel filter
  • Ignition switches

Ignition coil:

You could have a faulty ignition coil. You can notice your ignition coil isn’t working properly when you experience a sudden loss of power or waste more gas than usual.

Crankshaft position sensor:

If your crankshaft position sensor is malfunctioning, you’ll quickly realize it because the engine tends to vibrate in that scenario. More importantly, your engine light will come on.


As a final note, I know I said it’s not the battery – but it could be that. Now, hold on. There’s a reason behind this change in my line of thought. You don’t have a dead or drained battery in this scenario; instead, you could have the wrong battery for your truck.

That’s right! If you have the wrong battery, you will have all sorts of issues happening, and taking thirty minutes to start your truck could be one of them.

It takes a lot of “cold starting amps” to turn a big diesel engine over!

Broken starter:

When your battery is okay but the car won’t start, you should check your starter. Do you hear a clicking noise when you turn the key? You probably have starter trouble. I have talked about this above more thoroughly.

Ignition switch issues:

Similar to a broken starter, you could have ignition switch issues if you try to start your car and only your lights come on. A great way to differentiate a broken starter from ignition switch issues is the clicking sound in this scenario, you won’t hear it.

Clogged fuel filter:

It’s far from likely, but every once in a while, you have to deal with a clogged fuel filter. Why do I say it’s unlikely? Because your fuel filter could clog after 10,000 miles – but it’s not a sure thing. If everything else is doing okay, this is probably it, though.

Why is there a delay when I start my vehicle?

When your truck takes a little longer to start than usual, there are a few issues behind that behavior. You could have a faulty battery, a malfunctioning alternator, or a drain in the electrical system.

You have to make a distinction here. Does your truck have a delay when you haven’t used it in a while? That could be because of a weak battery. Your truck could have electrical issues as well.

In that case, is your battery older than four years old? It may be time to change the battery.

On the other hand, does your truck takes time to start after you recently used it? That’s another story entirely. Your engine could be overheating – and that could prevent you from starting the truck for a little while until it cools off.

There are other issues that could trigger this behavior, but it often comes down to the battery or the engine. A dead battery isn’t that bad, but engine trouble is something to take care of as soon as possible.

If that problem persists, you need to take your truck to a mechanic. Otherwise, you may end up with a truck that won’t start at all.

How can I tell if my car isn’t starting because of the battery or starter?

The easiest way to tell if your car has battery or starter trouble is to turn on the lights. The lights rely on the battery – because of that, you probably have a starter issue if they turn on. On the other hand, if you can’t turn the lights on, you have a dead battery under the hood.

Signs your car battery is giving you trouble

  • You try to start your car but the only thing you get is a whirring sound in return
  • You can’t use your key fob to lock and unlock the doors
  • Most of the electrical parts (lights, radio, etc.) are dead

Signs your starter is the problem

  • There’s a clicking sound when you try to start the car
  • You can’t start your car but the lights turn on
  • You try to jump the car and it does nothing at all

What to do when your car won’t start

Once you figure out what’s wrong, there’s not much to do other than replacing the faulty parts.

It’s likely that the problem is a dead battery. Most batteries last anywhere from two years to four years, depending on their quality and how much you use your car.

The good thing about this scenario is that you can jump your car and drive it to a repair shop. At least you don’t have to wait for a tow truck and can drive yourself to make things faster.

Don’t rely on jumping your car to drive around, though. You can do more damage than good that way.

On the other hand, if we’re talking starter trouble, you’re going to have to call someone to pick your car up. You can also tell someone to come and replace your starter – or do it yourself.

What causes a car not to start if the battery is good?

Sometimes, your car won’t start even if the battery is fine. That’s when you have to start trying things out to see if you have ignition switch issues, starter trouble, a clogged fuel filter, or a more simple issue.

Alright, I’ll start with the simplest issue you could be facing: not having enough gas! That’s right. You could be missing the obvious.

Trying to start your engine and seeing it fail could be frustrating enough to blind you from what’s happening. I’ve seen it happen before, so don’t be so quick to dismiss it.
