Make sure the pins are straight and that the connector is fully seated.

What happens when you run out of gas?

And while that may seem like a relatively minor inconvenience, running out of gas has several long-term consequences for your vehicle, including increased fuel pump wear and fuel pump overheating. Running low on fuel can also cause the fuel pump to pick up sediments, which clog the fuel filter, fuel injectors, or high pressure fuel pump.

Why is there no gas coming out of my gas grill?

Why do sparkplugs in my engine keep blowing out?

As to why it continues to work despite having no ground electrode….the spark is being made by using some other local piece of metal as the ground, like the head. It’d be a longer spark, and weaker, so more likely to blow out from compression, giving misfire. But at least it’d fire most of the time.

How are spark plugs related to carbon monoxide?
