If the engine fails to start during the repeated start again, check whether the low-pressure branch of the fuel system is in a good condition and/or bleed the fuel system.

I have never heard of bleeding a fuel system, but when anything "bleeds," a liquid is usually draining. If a person or animal bleeds, it obviously is losing blood. When some dyed fabrics are put in water they "bleed". That is, the colors run together (and all over any other clothing nearby). When you bleed the brakes, you drain the brake fluid and then refill the reservoir and pump the brakes to get the air out of the system. Therefore, my guess is that the fuel system needs to be drained. Be sure to observe all safety precautions associated with handling fuels in open containers.

They want your to remove any air from the fuel system. An engine won't run on air, you must have fuel. Select a point where the fuel line is as close to the fuel injectors/engine as possible. With the key on (fuel pump running) loosen the fitting only enough to allow air to escape. The fuel will push the air out. As soon as fuel is coming out tighten the fitting. You may have to do this a couple of times. Once you get the engine started and run it for a while this will no longer be an issue. Even if there are tiny air bubbles in the fuel system they will be forced through the injectors and exit the engine through the exhaust system.
FYI. I am not a professional mechanic but I am a fairly good shade tree variety. I have bled perhaps 10 - 12 fuel system in my life and have never had it correct any problem.
Good luck on your endeavor.

It means you have to get rid of the air in your fuel lines.
Here is a step by step to follow if your not to confident take it to a shop to get it done.
(1) Make sure fuel tank shut off is in "on" position.
(2) Bleed the air from fuel filter. Loosen the air bleed screw at the top of the fuel filter body and operate the manual handle of the lift pump until the air bubbles completely expel in the fuel flowing from the filter.
(3) Bleed the air from the fuel return pipe installed on the fuel injector, and bleed the air by operation the manual handle of the lift pump. (If there is more than one injector, bleed the one at the end of the line).
(4) Bleeding the air from the fuel line - ( line from the filter to the injector pump). Loosen the air venting screw at the injection pump and operate the manual handle of the lift pump until all the air bubbles are out.
(5) Bleed the air from the fuel injector. Loosen the nipple on the fuel injector side, set the throttle to half and the decompression lever to the decompression position and crank engine. When no more bubbles appear in the fuel flowing from the end of the injection pipe, re-tighten the nipple.
It also sound to me like your having problems starting your car, if so turn the key but not all the way and listen to see if you hear your fuel pump, if not you may have to replace your pump....

It means to release a little so that you can check to see if anything is actually coming through the line.
