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 :rofl:

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

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.

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

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.

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.....

      The team at OBD2 Australia are pretty good, shoot them an email and ask them. I've dealt with them before for work stuff. I'd be shocked if it didn't work, so long as Consult can activate the ABS. But you might need to use KLine for it which would be the stopper, as I don't think that piece does KLine comms.

      Yeah and hence my ghetto way of slamming the brakes, get the ABS to cycle, rebleed seems to be a sensible workaround.

      Hey! Happy to help. Nothing inherently wrong with the adapter, it's more so with Brett Collins himself. He gave me a lot of incorrect information when I was in contact with him and was extremely rude when I challenged him. He stated I could not use any aftermarket twin plate clutches except for his own, not to use the dush shield, bla bla bla and it was all BS.  Collins stated to cut roughly 14mm's off the housing, I took off 15mm to make room for the dust shield. I would confirm with whatever adapter manufacturer you're using.

      There's plenty of OEM steering arms that are bolted on. Not in the same fashion/orientation as that one, to be sure, but still. Examples of what I'm thinking of would use holes like the ones that have the downward facing studs on the GTR uprights (down the bottom end, under the driveshaft opening, near the lower balljoint) and bolt a steering arm on using only 2 bolts that would be somewhat similarly in shear as these you're complainig about. I reckon old Holdens did that, and I've never seen a broken one of those.

      Let's be honest, most of the people designing parts like the above, aren't engineers. Sometimes they come from disciplines that gives them more qualitative feel for design than quantitive, however, plenty of them have just picked up a license to Fusion and started making things. And that's the honest part about the majority of these guys making parts like that, they don't have huge R&D teams and heaps of time or experience working out the numbers on it. Shit, most smaller teams that do have real engineers still roll with "yeah, it should be okay, and does the job, let's make them and just see"...   The smaller guys like KiwiCNC, aren't the likes of Bosch etc with proper engineering procedures, and oversights, and sign off. As such, it's why they can produce a product to market a lot quicker, but it always comes back to, question it all.   I'm still not a fan of that bolt on piece. Why not just machine it all in one go? With the right design it's possible. The only reason I can see is if they want different heights/length for the tie rod to bolt to. And if they have the cncs themselves,they can easily offer that exact feature, and just machine it all in one go.
