Can low gas make Check Engine light come on?
Bottom line: Yes, if you see a pattern in which the engine light comes on during periods that your tank is low, then turns off right after you fill it (and tighten the gas cap!), one of the above issues is probably going on.
What happens when your check engine light goes off?
You wouldn’t think a gas cap would be that important, but it is. When it’s loose or cracked, fuel vapors leak out and can throw the whole fuel system off. This causes a reduction in gas mileage and increases emissions. If you get an error pointing to the gas cap it means fuel vapors are leaking out of your cap.
How can you tell if your car has low fuel pressure?
You might also hear some spluttering while trying to start your car. If your car’s engine stalls while running or at idle, it is a clear sign you are having some problems with your fuel pressure. This may be due to fluctuations and sudden drops of the fuel pressure.

What should I do if my fuel pump is low?
The first thing you can do is to check the screen filter. The screen filter protects the fuel pump from dust and debris and can get clogged up pretty quickly. This can hinder the flow of fuel to the fuel pump and into the cylinders. So, it is better to clean the screen filter and replace it with a new one if needed.
