Why Car Is Not Getting Gas To Engine

If you’re certain that you’ve got enough fuel in the tank, the following issues could be the cause of the problem. However, depending on the type and model of the car you drive, there might be other reasons for this challenging situation.

1. Faulty Fuel Delivery System

Apparently, fuel doesn’t jump from the tank to the engine; it passes through some channels before it can get to the engine.

Thus, when these channels are faulty, bad, or damaged, it becomes impossible for fuel to get into the engine, which causes be the reason for the issue you’re facing.

Troubleshooting the fuel delivery system should start with checking the filter to ascertain if it is clogged. A clogged fuel filter won’t allow fuel to flow freely, likewise, a faulty fuel injector won’t pump (“inject”) fuel into the engine.

The first place to check when it seems your car is not getting gas to the engine is the delivery system (fuel pump, injectors, and filter). But if you check and the delivery system looks good, it’s time to check another place.

2. Fuel Pressure Regulator

In some cases, the reason why it seems like your engine isn’t getting fuel is due to a faulty fuel pressure regulator. When the pressure regulator is faulty, it tends to malfunction. To check this, you need a pressure gauge; you could rent from a friend.

Usually, in every car manual, the manufacturer indicates the specifications for various components. There’s a section that details the pressure specifications for your car.

So, when you connect the pressure gauge, check if the reading matches what’s specified in your vehicle’s manual.

If the reading doesn’t match, it could be that the pressure regulator is the culprit here. So, you should get it replaced.

Other Possible Causes

Since modern cars are more connected than ever, an electrical fault can cause the mechanical systems in a car not to respond or function properly.

In a situation where you have checked your vehicle’s entire fuel system and everything looked good, you should try troubleshooting the car using an OBD scanner.

More so, the spark plugs could be the reason why your car is not firing. There are a number of reasons why your engine isn’t starting even though you’ve filled the gas tank. It is advisable to have a mechanic check the car to know what’s actually the issue.
