Yes, it can block a filter or destroy an injector. Fuel lines should never have rust in them, since fuel is an oil based material that actually prevents rust. If you have rust in the fuel tank it's because condensate has been allowed to build up. You need to take care of the problem.
Yes, along with many other causes a bad fuel pump relay can cause a no start. The fuel pump relay provides power to the fuel pump.
Two things, the fuel filter and most vecihles have two pumps one in the front and the one in the tank.
transmission stop engaging, after fuel stop, why
most common failures fuel pumps or pump relay eec relay, crank or cam sensors if no crank bad starter or security disabled
You have air in the lines and they need to be bled out.
When fuel lines freeze, a vehicle will have a hard time starting on a cold morning or may sputter and stop while driving. Once unfrozen, the vehicle should run properly.
Washing doesn't stop rust to return.
If the fuel filter is clogged, or a new filter is installed backwards, it will prevent the fuel from reaching the combustion chamber and prevent the veficle from starting.
Does it have fuel/spark/compression?
Look for an anti rust spray.
Your Jeep Wrangler is not getting the proper amount of gas if it stalling when you come to a complete stop. This could be your fuel pump, fuel lines, or the intakes.
Fuel lines may have lost their prime try turning key to "on" position for about 10 seconds without trying to start vehicle - Do this twice may be eough to prime fuel lines
Its called auto start stop to save fuel
Remove the power supply, order the robot to stop on the controlling computer, or unconnect the fuel lines.
Not just one. It will still start but will miss.
this question makes no sense ? i assume you mean prevent the car from cranking??? if so then no. a bad fuel pump may stop the car from running or starting but it should not stop it from cranking. a bad fuel pump relay could stop the car from cranking but that would depend on the year make and model of your car.
no it can not
