Yes it can if one or more cylinders is missing. Those cylinders are wasting fuel.
It could.
After you replace your head gasket your compression in that side will be higher, I highly recomend to anyone that has to replace a head gasket that they do BOTH sides. With all the electronic checks that happen in newer vehicles a difference in compression can cause confusion in the electronics. poor fuel mileage try changing o/2 sensor sometimes blown head gasket wrecks sensor and causes poor gas milage
Yes, it can. Other causes include ignition and fuel systems.
if the fuel pump is bad it's not delivering fuel to your engine so yeah it would prevent it from starting. Your car will start with a blown or bad head gasket....but you'll loose water and it will mix with oil...it's not a good thing...but yes it will star
Yes, removing a catalytic converter can increase fuel consumption because it can lead to inefficient combustion of fuel, resulting in higher fuel consumption. Additionally, the engine may not run as efficiently without the catalytic converter, causing it to burn more fuel.
Possible problems: 1. Clogged Fuel Filter 2. Water in Fuel A. Bad Fuel Supply B. Blown Head Gasket
you might have blown a head gasket,was the car hot when it died? was and is it blowing smoke more than normal, if so u might have blown a head gasket you might have blown a head gasket,was the car hot when it died? was and is it blowing smoke more than normal, if so u might have blown a head gasket or you might try your fuel pump relay switch, i`d try and get some codes first that's the short answer.
Bad spark plug and or plug wire. Possibly burnt valve or blown head gasket. And if the engine is mulit-point fuel injected, a malfunctioning injector. A compression test will eliminate a burnt valve or blown head gasket.
A blown head gasket will not show up on a diagnostics test but can show itself through the readings of several different sensors. The sensors will tell if anything is wrong with the airflow, coolant flow, or fuel flow of the engine.
If the oil is turning grey, it could be a blown head gasket, or busted water jacket. If it's fuel in the oil, it depends on what kind of fuel system. Fuel injected systems can have leaking manifold gaskets and leaking injectors. Systems with carburetors can have stuck floats causing fuel to mix with oil. Water doesn't hurt as bad as antifreeze, which can damage bearings. Fuel in oil thins the oil lowering its viscosity and causing more wear.
This could be due to one of two things. If you have a diesel, then it's either the fuel shutoff solenoid or a clogged fuel filter. For a gasser; clogged intake, clogged fuel filter, distributor problem, blown head gasket (causing antifreeze to leak into the head), anything electrical on a gasser.
The most likely culprit is a blown gasket or cracked head on one of the cylinders, where fuel lines and coolant lines intersect. This can pull fuel into the cooling system.
