car takes 4-6 seconds to start

[JoeFish]

G'day,

I've come across a problem of when I start my car in the morning or usually when I havn't driven her for about an hour or so, it takes about 4-6 seconds for the car to start/turn over. I have to hold the key fully turned as the car keeps on trying to turn over and start.

It's not like a flat battery where it tries to start then stops, so you gotta repeativly try to turn it on. With this I just hold it for about 5 seconds until she fires up.

I was told it could be an electronic sensor by a few mates who are mechanics and also an auto electrician.

but what do you guys thinks?

Cheers

well i changed myn, and that wasnt the problem, still trying to solve it?

[JoeFish]

changed your what?

and I haven't done anything to fix it yet.

[GetToDaChopa]

Starter motor?

[JoeFish]

I am hoping not lol

Auto electrician heard it when i was getting some fuses off him and he said that it's most probaly a sensor that configures how much fuel needs to go in and all this jazz lol.

Is there a way of getting your sensors checked to see if they're working properly ??

thanks

pcv pipe loose? throttle body pipe loose? fuel filter partially clogged?

[JoeFish]

I got a new fuel filter about 5 months ago.

Don't know about the rest.

my CAS...lol

does it start EVERYTIME after a few seconds?

If so I'd say don't worry about it because it is unecessary cost. Just check your alternator is working fine and you shouldn't have any issues with the battery running down too much.

[JoeFish]

Thanks mate,

Well if i start it just after I have already had it going, It will start straight away. It only does that when I first start her in the morning or when she has been parked for an hour or so.

I got a new battery late last year and I also had the wiring harness replaced for the alternator late last year as well.

The next time you go to your car in the morning turn the ignition on (all lights come on instrument cluster), pause 3 secs, and off then repeat 2 - 3 times before cranking and see if it starts straight away.

this is what i had to do with my car, when i got it converted to gas, sent it back in un happy and got it re tuned, starts first time everytime now, was so annoying, turn ignition on, turn off, then start again was the only way to start it

[JoeFish]

So i done what you suggested above and you were right, it does start pretty much instantly.

What is the reason of this then?

cheers mate!

[JoeFish]

Any idea's what is causing this??

thanks

[been there]

Sounds like a fuel pressure problem to me, your fuel pump may be on the way out, or lazy at best.
It may be taking some time to spool fuel up to the fuel rails.
What cycling the key on an off does is turn the fuel pump on and off a few times..

May be worth checking the fuel system, both for leaks, constant pressure and starting pressure.
A Fuel line pressure tester is the easiest way, or drop it in to a mechanic and leave it there overnight so its cold.
I Had this issue with a 5ltr last year.

THanks heaps for that advice man! That is most probably it!

Because when i get home and park my car in the garage, once i turn it off you can smell fuel. You can usually smell it if i park her outside but since the garage is closed in it's easier to identify the smell.

ALSO like i have stated before, when i go to take off (when the engine is cold) it's as if the accelerator doesn't register even if i have it to the floor. I don't punch it anymore at takeoff when it's cold because when she does kick in...SHE GOES! But it is usually a jumpy start.

I will defiantly share this with the mechanic.

Any other advice or idea's??

Thanks once again! 8-)

could be fuel pressure regulator to, dumping fuel into the intake via the vacumme, this could also be making it loose pressure in the morning.

[wortus]

It could be low fuel pressure due to a worn fuel pump or possibly the carbon purge cannister it's not meant to purge into the engine when it's cold and if the car has been sitting a while petrol fumes condense in the cannister and are being sucked into the engine at start up. You may want to check the system that stoips this purge happening until the motor is warm and at high speed. On a VS it is an electrical solenoid not sure about a VT it is probably the same though.
Also how many KM on this car? The in tank fuel strainer should be replaced at around 200,000km (thats the specified time on a VY.

[JoeFish]

thanks dude!

yeah well the mechanic said that it is the fuel pump pressure...I'm not entirely sure.

I've kinda gotten over it but it still gets quite annoying when I'm in a rush haha!

thanks for all your advice!
