Car wont start after getting gas
If you can’t start your car after getting gas, you’re probably dealing with a faulty fuel pump. More often than not, this kind of thing happens after not putting gas in your car for a long time or having little to no fuel before filling the tank.
The problem with having a faulty fuel pump is that you can’t check it out for yourself unless you really know about cars.
A mechanic will help you diagnose (and fix) the issue in no time. He will check the fuel pressure first and the voltage second.
A fuel pump with no pressure but enough electrical power to work needs to be replaced.
Do not mistake a faulty fuel pump with a case of fuel flooding, though.
In this other scenario, someone stepped on the gas when you were filling your tank, and that caused the gas to go where you don’t want it to go. I’ll cover this problem at the end of the article.
For now, I’ll say this: fuel flooding is a better problem to have than a faulty fuel pump – because time will fix that problem.
On the other hand, you’ll need to pay to replace a faulty fuel pump.
How much does a fuel pump costs?
It can be anywhere from $200 and $1000. That’s right! This is not the kind of problem you want to have unless you like spending money.
A worn-out fuel pump can also cause fuel waste, engine sputtering, and an overheating engine.
Why won’t my car start after filling up the tank?
There’s such a thing as putting too much gas in your gas tank. It could lead to gas overflowing where you don’t want it to go. Then, sooner rather than later, you’re having trouble starting your car – or worse.
What’s the right amount of gas for your car?
I suggest filling three-quarters of your gas tank if you’re having trouble starting the car after getting gas.
Any more than that and you may start to overcrowd your gas tank – and you’ll end up with the same issues as you do when you go over the top.
Why does that happen? Because there are fumes, oxygen, and a few more things in your gas tank other than fuel – and they all need space as well.
Not sure how much gas can your car take? You can check for your gas tank capacity online or in your car’s manual. It’ll probably be somewhere between 12 and 15 gallons of gas, though.
Why does my car sputter after getting gas?
Your car will sputter after something clogs or because of poor-quality gas. You should check the fuel filter and pump if you’re sure you used quality gas. Otherwise, you need to change gas stations.
There’s poor quality fuel out there, and it’s something you need to stay away from. It’s full of impurities that can wreck your car.
What is bad fuel?
It’s poor-quality fuel full of impurities and debris that can damage your engine. Certain gas stations buy it because it’s cheap. While others, sometimes, under no fault of their own, receive a bad batch of it without knowing.
You may buy a bad batch of fuel without knowing too. Most of the time, you know there are shady gas stations that sell cheaper fuel (for obvious reasons) – and you need to stay away from them.
Anyway, when you use bad gas you end up clogging your fuel filter and pump. After that happens, you have to go through the job of flushing it to make it work again.
In a worst-case scenario, you may wear out or break something after using poor-quality gas. I’d avoid cheap low-quality gas if I were you.
How do you know if your car won’t start because of gas?
When you’re having an issue with your car, it’s probably because of some sort of problem with fuel. The three most common options are not enough gas, having too much gas, and gas going where it’s not supposed to go, also known as fuel flooding.
Not having enough gas to start the car sounds like a pretty simple scenario to understand, doesn’t it? Well, it’s more complex than it sounds.
When you run out of gas, your car will change in more ways than you think. You’ll have no chance of accelerating – and you’ll also have a hard time hitting the brakes.
That’s right! Having enough fuel also helps you slow down and steer. If your car died on you and you have a hard time pulling over, you ran out of gas mid-drive.
Too much gas
You can have too much of a good thing – and filling your gas tank to the top is a perfect example of that!
Why shouldn’t you fill your gas tank completely? Well, as you know, your car turns fuel into energy via combustion – and, in that scenario, there are plenty of moving parts that come into play.
Take your charcoal canister, for example. The excess fuel goes there if you go overboard when filling the tank. Your charcoal canister can’t take that excess for long – and, eventually, fails.
Now you can’t start your car and need to replace the canister – that can cost up to $1500!
If for some reason, you pressed the gas pedal while someone was filling up the gas tank, you may have caused fuel to go where it shouldn’t go.
Now your spark plugs are soaked with fuel. In that scenario, you need to wait until they’re dry to start the car.
You can tell this is happening because of the gas odor that you will suddenly have inside your car.
Your spark plugs are in charge of generating enough voltage for you to start the engine – but they cannot work when they are wet.
The good news is you only have to wait for 20 minutes before they dry and you can get going.
