A Habit Ive Picked Up...

[br3ndan]

Hey guys,

So ever since i got my skyline ive gotten into the habit.

When i turn on my car.. ill turn the key two times and wait until my air bag light turns off (about7 seconds) before i turn it one more time to turn on the car.

My thinking is that it gives the car ecu time to load as well as time for the fuel pump to prime.

Now what im wondering is... i am wasting my time ? is there any side effect of me just turning on the car straight away? Or am i doing the right thing?

Cheers guys,

Brendan

Do you have an after market fuel pump? If so (and it's nice n loud) turn the key to ignition and listen. After a few seconds you'll hear that the fuel pump stops pumping, it is from that time on that you are wasting your time waiting any further

I do it too mate; all good.

I kinda like popping the bonnet while the engine warms up so i can listen for any strange noises before i take off; another habbit.

We all have them; like our little OCD

[gfunkk]

yeah i wait for the fuel pump to prime before starting

then after starting i sit there and twiddle my thumbs for 10 seconds before slowly taking off

ECU to load up/airbag light to turn off.....yep wasting your time.

Aftermarket fuel pump to prime up, ok thats fair enough.

Hehe - I do the exact same thing - but only from cold (if i know i haven't used the car for hours).

[GTR-N1]

...depends on if I need to be gone in 60 seconds

[RB30-POWER]

i always let the pump prime, then crank/start.

the fuel system will hold residual pressure for a couple of hours if the checkvalve in the pump is good, so no real need to prime again if the car has only been off for a short period, it should fire straight away.

[tin-pain]

usualy like most people u turn and wait for the fuel pump.

but as for the airbag u got no worries.

cause the computer just trys to sense a fault but when it knows everything is ok it turns off.

Ha ha... I always wait for the fuel system to pressurize in any EFI as well, otherwise it won't start properly.

[Kujotk]

never been told about this before but i always turn accesories on for a few seconds before cranking it over, stock fuel pump but i can hear things swithcng on before i crank it..... stock or not theres no harm in having everything set up for a couple of seconds before the power is drawn to the coils and what have youfor the task that drains the battery pretty quickly for a start

[blind_elk]

Well, from observing when I have a fuel pressure gauge attached, it takes about 1 second for the fuel pressure to come up.

[mad082]

ummm, why do you turn the key twice?

depending on where you are turning it to you could be getting the fuel pump to start then stop then start again, which probably isn't the best thing for it.

[TTT]

lol.... just start it straight up man..

what a crack up waiting for lights and noises.

key in, check not in gear, crank and it starts.

[quarkgun]

So you guys saying you shoulnd't be able to hear the stock fuel pump? I can hear mine quite clearly when turning the key

[RB30-POWER]

you can hear it for 5sec or so as it primes. this is normal.

[l_uk3y]

I can hear my stock fuel pump clear as day (even whilst driving ) but only cuz the rear seat is out and the boot is stripped. When its all in its a lot lot quieter but can hear it on the very initial start up even when everything is actually in the car. I just give it say 2 seconds of key before i start. Never had a problem.

thanks for all the replys!

what i meant by turning the key twice is that you got two stages before the car starts cranking. The first i beleive is acc. then the next one is on, the third cranks the car.

i usually switch it to on, and wait for fuel pump to prime etc, before turning on the car.

looks like ive been wasting my time!! haha.. but some habits are hard to break eh.

[eMsta]

I have something similar - I click my fingers a few times before I open the toilet door to go to the mens room at work.....
