Gas line frozen in car??!!!?

If your car is fuel injected and you let it get to empty you can fill the tank on a hot day and it will never start. Why? Some cars do not have self priming fuel pumps mounted in the tank. If so, when you run on empty, the fuel system can't keep enough pressure in the lines. So, you may have put air into the fuel lines. The engine is now trying to suck fuel just like you would trying to suck water through a straw that has a hole in the the middle of it....doesn't wotk too well. The fuel rails need to be pressurized. Unfortunately, in most cases, you will need to get it to a mechanic to do this. Before you do this, you may (long shot) be able to squirt some starting fluid (DO NOT USE GASOLINE) into the intake and try starting it. If that doesn't work, you are going to need to get it towed to a mechanic. Don't let your car get to empty.

Other reason you don't let your car get to empty is there is sediment in your tank from the stations tanks. Filter in your pump are supposed to stop that stuff from clogging anything, but sometimes a small piece of rust or other crap will do it if the fuel level gets too low and guess what....your car won't start because a fuel line is now clogged from sucking that crap up. Keep your tank at least one quarter full and this can't happen.

Is it an old truck, car, van, straight four, 6 or V8? Carb or injection, make model 12 months engine style all helps to support you. Is the gasoline tank 1/4 half or full? Add a iciness fuel additive and hold the tank FULL in the wintry weather to prevent water condensation entering the fuel line and freezing. So all we understand it is petrol (fuel) and that is not going to start in bloodless temps? Does the starter turn the engine with the headlights on without the headlights dimming? If yes then the battery and starter are nice and you have got a gasoline situation. If no, carry the battery indoors and use a trickle charger. If it nonetheless won't give 12volts below heavy load then trade the battery as contemporary electronics will not fireplace on 10volts (a single dangerous cell). If the battery is now warmed and voltage ok underneath load, spray some quickstart (ether) down the air inlet and it will have to start, however we have to unfreeze the gas strains or it won't run for lengthy. It wishes to be brought into a heat storage or constructing or parked in the daylight for a while then fill the tank with excellent gas. In bad weather see if you could run an typical inspection lamp from the residence to beneath the bonnet, or better but set up a block heater. It'll best cost a few pennies a night but save various grief within the morning.

Gasoline does not freeze, diesel fuel will produce wax if cold enough. What type of fuel does the car run on?

If it's gasoline then the problem is probably in the fuel pump/carb or you've sucked up crap from an empty tank.

If it's diesel then there could be waxing blocking the fuel filters.

In both cases if the engine is turning over it's not frozen, you have a fuel blockage.

Your coolant may also be frozen but that will not become a problem until the engine is running.

First put a charger on the battery while the car warms up.

Then

Put a couple ounces of gas in the throttle body.

If it starts for a few seconds you confirm it's fuel.

It can be an ignition problem.

If the engine spins much too easily with the starter, maybe it's the timing belt.

Electrical components that are on their way out can have issues based on temperature. If you can get the car in a garage or something, you might try to start it after it warms up a few degrees. It's not the gas.

If gas is an American term for fuel, try warming up your glow plugs if it is a diesel. In the cold weather, they tend not to work so well
