Sequence of sounds at startup
I'm not looking for a tongue twister, but instead a tutorial. Can you guys tell me what all these sounds mean?
Begin with a dead cold engine and turn the key: Chick - Chick (sounds like it comes from the passenger front of the engine) ZZZZZZZZZZZ (fuel pump, I think) Click (under the driver side windshield wiper, starter solenoid, I think) And what happens when I don't hear the ZZZZZZZZZZZ that I think is the fuel pump priming? |

Re: Sequence of sounds at startup
Your ABS pump makes a noise before starting as well. Thats behind the drivers seat

Re: Sequence of sounds at startup
I've noticed the ABS making noise only after beginning to roll from a stop (accompanied by ABS ACTIVE telltale lamp).
If the ZZZZZZZZZZZZ fuel pump sound is not heard, it's probably because the rail is already primed (due to recent engine running or prior key-on prime cycle). Or a dead fuel pump, fuel pump relay, etc. |

Re: Sequence of sounds at startup
Sounds all normal except the part where the engine cranks at the end and starts.

Mine doesn't run for 1 second as you describe. Just FWIW.

Re: Sequence of sounds at startup
I drove my car yesterday and the fuel pump did not run before starting the car. And the car started fine. 3 times.
I think I remember in the past the pump would run until I started the car. |
