Yes it does. But you can not run a mechanical pump on a fuel injected engine. It will not pump enough fuel to run the engine.
No, of course not. The fuel pump supplies fuel to the engine. The engine will not run without a supply of fuel.
Electric fuel pump--Usually always when the ignition is on. Mechanical fuel pump--When the engine is turning.
yes if you need new fuel pump, the engine is not getting fuel. therefore no fuel equals engine wont run
If the key is in the on position and the engine is not running, the fuel pump is off. If the engine is running then the fuel pump is also. During the start cycle the pump will only run for 3 seconds unless the engine starts.
Yes. Without a fuel pump the engine will not be supplied with any fuel and it will not run.
Your new fuel pump is apparently defective. A fuel pump is required to supply fuel to the engine, and the engine cannot run (and of course not start) without a supply of fuel.
As long as the engine is running, the fuel pump is running.
Yes, without a fuel pump supplying fuel the engine will not run.
fuel pump will not run... no fuel to the engine.
A bad fuel pump will hinder the fuel supply to the engine. The engine can run rough with an inconsistent supply of fuel, or it will completely shut off.
If you turn on the ignition without starting the engine you should hear the fuel pump run for a few seconds. This is a good indication the fuel pump is good but not 100% positive. A bad fuel pump can run but not pump fuel. If you hear it for run for a few seconds just replace the fuel filter to make sure it is not clogged. If it still does not pump have a fuel pressure test run to verify the condition of the pump.
