Title: Hissing sound on cold start, second start normal
Post by: daugavpils on 20 November 2011, 08:50
Hi All,

 During the last week I had start up issues with the car.Almost every morning when I turn the ignition on for a first time, car does not start but I can hear a constant hissing noise for as long as I hold the key to the right.However when I turn ignition again it started ok everytime.Is it something easy to diagnose?I hope it is not something serious to break the bank just before Christmas shopping starts.

So it hisses when you turn the key and hold in position when starter motor normally Kicks in?
Or do you mean it hisses when ignition turned on?

Hi

 It only hisses when I turn the key and hold it in the position.Nothing else happens, engine does not start but the constant hissing sound persists.When turn it off and turn it on again, engine starts instantly.

Sounds to me and I think Stainesy was hinting at it too, that the starter motor is causing the noise as it might be siezing up. Best thing is to get a video up of the noise from the engine bay

Sounds like the starter solenoid is sticking on the motor. It should spring out and engage your flywheel to turn the engine over. Its hard to make out if your engine is turning over, but dont think it is on the first try. New starter motor time me thinks.

Yeah defo need a new starter motor mate. Mine did exactly the same for about a week then totally went. In the end it will just make a high pitch whizzing sound where it's spinning but not spinning out to engage with flywheel.

Easy job mate. I did mine in about half hour no need to jack car up or anything. Just stick a jack under the gearbox and take the weight maybe jack it a little bit.
Undo all the wires and connectors remembering where they go.
Undo the bolts that holt it to engine mount bracket. And remove.
Then fitting new one is reverse of that.

I found it easyer to take take bolt out of engine bount braced to mount. Then you can hold bracket with hand and line up 2 bolt easy then lower gearbox down into mount position with bolt in. If that makes sense lol.

I assume new starter motor means trip to my local rip-off garage?

Sorry just read it now.So I guess it is doable, I just need a new starter motor :)

As above

Also check the wiring to the starter, check the earth points for corrosion on the solenoid but its sounds like how mine did last year which at the time I paid £70 for a new remanufactured one from Bosch.

Thank you Leon27,

As above. Mine does the same from time to time, starts fine on the seconds start.

I got this one. http://www.ebay.co.uk/itm/VW-GOLF-MK3-2-0-8V-GTI-1992-97-STARTER-MOTOR-ST045-/370558437999?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item5647010a6f

 Cheaper than anywhere else I found, and you get a 2 year warranty which is exactly the same as any other branded ones.

I went to German and Swedish cost £90 but got £40 back when I took my old broken one back to them. I just took mine off then went to them so only payed £50.

Does this sounds like a reasonable explanation http://au.answers.yahoo.com/question/index?qid=20101010205642AA1VFtL too?

Because what you're experiencing is the starter gear not engaging with the flywheel and spinning the engine over. The "hissing" is the starter motor gear spinning freely.

The problem in the link you posted is far more complicated as the guy is running LPG & petrol and it's backfiring and running rich, so it's totally irrelevant.

Ok, thank you for the clarification.

Maybe I was unclear but I was referring more to the solution suggested than the problem that guy had:

"...the problem of starting on the second try is normally because the fuel pressure has bled off the injector rail while the car sat. The check valve (normally in the outlet of the fuel pump) is supposed to keep the pressure up for many days but a leaky check valve or dripping injector can bleed off the pressure in minutes. When you crank the first time the fuel pump runs to restore the pressure, and when you crank again it is ready to run. I'm not familiar with the Mazda, but most cars will also start on the first crank if the ignition is left in the "on" position for a few seconds (like 2-4 seconds) before cranking if the pressure has bled off."

I am going to monitor times between the failures.It seems that issue happens only if some time has passed that correlates with the explanation above.Also I will try to leave ignition in 'on' position as suggested above first thing in the morning.

Ok mate fair enough but that sound in your video is the sound of the starter motor spinning but not engaging with the flywheel.

If it was to do with fuel pressure the stater motor would still have engaged and turned the engine over. But it didn't.

EuroCarParts. I work in the trade so get a discount, if you have a mechanic mate I'm sure they should be able to arrange a similar deal :) Think as forum members we get some money off too... This might help
