Hi all,

So... a few months back I posted this:

http://www.omegaowners.com/forum/index.php?topic=106581.msg1333926#msg1333926

To sum up, the car appeared to not have all it's power and was shaking in general.

I have now went on a few months and it has worked fiiine. I only drive about once or twice a week when I am home and then not that far. What the locals (I'm in Sweden) are saying is that it is most likely a matter of condensation in the fuel-tank, since it's never really more than quarter-tank full, weather is cold and the car is driven maybe 10-15 miles a week.

The symptoms in the above thread have come and gone a bit. I was just about to try with more gas in the car and some carburator alcohol (or what you call it) to alleviate the problem but then it didn't start.

It has power and it tries to start but the engine simply doesn't fire. There's a quarter tank on...

What to do? Would it help with filling it up with more gas and then try? What do you guys think? Thanks a bunch!

Edit: As the attempts progress, it cranks less and less and the dashboard-lights grow fainter. Leaving it for a little while and coming back, it starts up with full crank that then dies down as there's no ignition...

Alright, additional information.

I tried starting it with jumper-cables from another car and while it cranks continuously then, the engine just doesn't fire. The plugs sound fine but it isn't igniting. The advice I was given was that there was too much water (condensation) in my gas.

My next question is - how does one alleviate that if that is the case? Should I pour more gass in the tank? (It's quarter-full now) or what is the advise? Do I need to empty some stuff out or what to do?

Thanks in advance for your help!!

Have you paperclipped it for any stored codes http://www.omegaowners.com/forum/index.php?topic=90581.0

cranks continuously then, the engine just doesn't fire

Possibly a code 19

[Pirvan]

I was reading up on those and might give that a try. It's a 2000 V6 2.5 petrol. Given that you suspect: 19   Incorrect RPM Signal

How would I fix that? Thx!

If you get a "19" the only fix is to replace with a genuine crank sensor

[Pirvan]

alright cool. Where are you all on the whole water in the gas situation from condensation?

Highly unlikely, do the paperclip first

[Pirvan]

Paperclip done.

I got

12 12 12 (Opening sequence, is a 2.5V6 petrol 2000 model)

13 13 13 --> 13   O2 Sensor 1 Open Circuit

31 31 31 --> 31 - No RPM (normal on v6 if engine not running)
Repeat

...

What is my next step? Thx!

[Pirvan]

Studied up a bit on the O2 sensor on the forum. Would a faulty O2 sensor be able to keep the car from starting?

[dbug]

Dodgy crank sensor doesn't always throw a code.  Definately sounds like a failed crank sensor - all the talk about water in gas condensation sounds like a red herring mate - car should start ok on quarter of a tank.  Would swap crank sensor for a good  genuine Vx one as first step

[Pirvan]

I never heard about the condensation before but apparently it is quite common here in Sweden. Maybe it's folklore amongst the car-folk but as a non-native and definitely not knowledgable about climate-effects on cars, I just go 'uhm, alright' and have researched it a bit. Apparently there's some dry-fuel and other stuff one can add and then see... But!!!

The crank-sensor you say? Is that something I can replace myself? Where is that? How much is it? Basically, what do I do next if I'm a relatively helpless scandinavian person? ...
Oh and what does a crank sensor do, exactly? And don't say it senses the cranking... that'll make me cranky.

Anyway, enough corny from here, thanks a bunch for your help and input, I'll keep you posted on what happens!

[Shackeng]

Given your engine type, well worth reading this: http://www.omegaowners.com/forum/index.php?topic=96562.0

Thanks! Looked it over and that will be one of the next steps. I've activated my network of car-knowing-pplz here and I still hear condensation in the tank i.e. too much water in the fuel as the most likely culprit. I've also looked on the internets!!! for symptoms of this and it matches fairly accurately (i.e. exactly) what has happened to my car. The only fault-code I got was 13 as well but the replacement of the sensor will obviously also be on the list if other stuff fails.

[spanish_lad]

so stick some more fuel in.. see if it starts?

[albitz]

Moisture/water content would have to be pretty high to prevent the car from even trying to start imo. My moneys is on crank sensor.
