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.....

      Have you put an aftermarket oil pressure gauge on and verified your oil pressure?   Noise being on the block, on exhaust side, how high up the block does it seem to be? It could be the VCT system getting cranky, especially if it's mainly at idle, and when warm, as that'll be your lowest point for oil pressure. Could be showing that oil passages / VCT solenoid are blocking.

      Well, hydraulic lifters will get noisy if they are dirty/fouled in some way, and exactly how that manifests will depend on exactly what schmutz is where. There is a procedure on here somewhere for dismantling and soaking/cleaning them. Replacing them with new is about 50% of the work and about 5% of the money!

      Ticking Sound On Idle - Rb25

      Thanks for the reply @GTSBoy this is is a hydraulic lifter engine. Yea right i did not realise the lifters were supposed to be compressible while installed. I could push them down but i had to lean almost my while body weight on them.  I have never heard of a lifter/ lifters ticking only at hot idle and getting worse the hotter it gets. I have owned a few jdm cars with noisy lifters. This noise is slightly more subtle, it is more of a sharp gentle metalic tic than the solid and more loud tapping I've heard on lifters. I have used a metal rod, alloy tube, hose and stethoscope and could not find the source of the tick. But it appears to be loudest on the actual engine block behind the exhaust cam gear and next to the oil filter. I had mate (40 year old mechanic) go over it with me and he couldn't find it either..  Could it be a cam seal issue of some sort?  Cheers

      This seems problematic and unlikely at the same time. Vanilla RB2Xs have hydraulic lifters. They do have "zero" clearance, but only when running with oil pressure inside them. When not running, you should be able to compress them and obtain heaps of clearance. RB26s and Neos have solid lifters. They should have ~0.3mm and ~0.5mm on the inlet and exhaust respectively. If they have zero clearance then bad things are happening. With nothing else being wrong, it would mean that the valves would be held slightly (ever so slightly) open when they are supposed to be closed and it should have all sorts of problems when running, caused by leakage in/out through the valves. Or, zero clearance can indicate severe valve seat recession. None of it is good. Have you used a piece of hose as a stethoscope to try to localise the noise?
