Can I cut back on wear & tear by turning my ignition to on and letting the fuel pump run before cranking? (only for the “morning” start).
Don’t think so, the fuel pump builds up pressure pretty quick and stops. You will really not do anything for the starter or the engine.
It won’t save wear and tear, but I think it’s a good idea. I wait a few seconds between “on” and “start” every time I start the engine in any vehicle.
In short… no. In most fuel injected cars the fuel pump runs for only 3-5 seconds before it shuts down. It starts again when the engine is running.
