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

Highly unlikely, do the paperclip first
-
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!
-
Studied up a bit on the O2 sensor on the forum. Would a faulty O2 sensor be able to keep the car from starting?
-
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 :y
-
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. :P
Anyway, enough corny from here, thanks a bunch for your help and input, I'll keep you posted on what happens! :)
-
Given your engine type, well worth reading this: http://www.omegaowners.com/forum/index.php?topic=96562.0
:y

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.
-
so stick some more fuel in.. see if it starts?
-
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.
-
Can you tell me everything I need to know about crank sensors? Can I replace them myself or what should I expect?
Thanks!

Alright, I have an update on the situation on this one...
I sent it to a mechanic and he couldn't quite figure it out. What we have is this - it's not water in the tank. They tried start-gas directly into the intake and it didn't even try to fire, it only cranked.
The spark-plugs don't give a spark, even though they've individually been tested to work. There are six spark-plugs and all the plugs on one side (three of them) are soaked in oil now.
So I am thinking it might be a relay or power distribution or some such issue? and what's with the oil on one side?
Your thoughts and assistance would be greatly appreciated! Thank you! :)

Get a decent mechanic is the first thought !!
You don't give the year/model/engine type of your motor .. but from your description I'm guessing its one of the V6 variants.
So, depending engine ... paperclip or pedal trick to read codes : http://www.omegaowners.com/forum/index.php?topic=90581.0
Non-starting as described without a code (you don't mention the EML so I assume its off) is probably a crank sensor : http://www.omegaowners.com/forum/index.php?topic=90540.0
oil in one bank of plugs is most certainly cam cover gasket & breathers :

http://www.omegaowners.com/forum/index.php?topic=90542.0
But first thing .. read the codes .. :)

Hi there!
Thank you for your reply!
I will get it to a proper mechanic, no sweat.
Most questions were answered earlier in the thread but I'll reiterate (Sorry I didn't before)
it's a 2000 2.5 V6 as you correctly surmised.
I did paperclip test and got 013 and 031. 013 is driver's side O2 sensor and 031 was simply cuz the engine wasn't on.
I'll see about that crank-sensor and otherwise with the oil stuff.. thanks a bunch!
btw, what should a fairly decent shop charge for this? What is my ballpark you think?
-
Everything on that list is doable by yourself I would imagine, nothing complicated at all, if you read the guides as linked .. :)
-
Can I suggest you re-visit your mechanic and insert the can of easi-start/start-gas up his arse......no professional would ever use easi-start on a petrol engine and its only ever a get you out of jail one off for a diesel as it casues major damage adn tells you jack all :y
-
Take it you don't approve Mark ::) ::) ;)
Constructive response though :) :) :y
-
As for the detail, the crank sensor signal needs to be seen before the ECU will:
1) Enable the fuel pump
2) Fire the injectors
3) Fire the spark plugs.
Hence no crank signal equals no fuel or spark.....an hence even ether wont make it run :y
