Hi all, really need your help chaps, car not missed a beat and went to start it last night and it won't start. All I hear is the starter, engine is not attempting to start at all. A friend said it was starter motor clutch but the looked and found that the aux belt is turning so probably not the starter.
Need help and possibly someone to fix it.
Thank in advance.

If your engine is spinning, then the starter is doing what it's supposed to do - turn the engine :y
What about the pedal trick & see if there any codes .... 19 sounds as though it could be a likely candidate. :-/ :-/
-
As Andy says, see if there are any codes stored ;)
-
Agree with mr B, pedal trick for fault codes, obd 2 code for crank sensor on your car is 0335 iirc, 19 is for the non drive by wire cars...

Ah! I didn't know that! :y :y :y

Yes tis 0335

So you may well see 10 flashes, 3 flashes, 3flashes, 5 flashes. From the car spanner light. :y

Just had another thought .... I know I know! ::)
How was it used the last time it started? When cars are started to just move a couple of feet, to allow another car of ther drive etc, and then switched off, you can easily end up with a flooded engine.
Try starting with wide open throttle. :-/
-
Well the code comes up 10 1 10 10. Which I assume is 0100. Which isn't really helpful

Just been through this myself with another car, would not start...trouble with that one was it gave a hat full of codes from maf to 02 sensor and several others but no crank sensor code. Cleared the codes, tried to start and failed, pedal trick again and got 0335 alone so conclusive eventually :-/
-

Ah, maf, unplug it and try again...

Will try but do you really think it will be that simple?

No, but needs eliminating IMO.... :-/
If it's no different still suspect crank sensor.....

Taking maf off didn't change anything.

Not maf then.
Crank sensor will often throw other codes, the ecu is fuddled as it does not have it's base reading from crank sensor IMO.
Ideally clear the codes and try again, needs a reader though...
-
I don't have access to a reader unfortunatly, is there anything else I can try to help diagnose it?

Keep trying and pedal tricking, it might start as they sometimes do, although mine just failed, no warning, no code other than erroneous ones....until cleared. :-/
Symptoms are classic crank sensor IMO. But really want to see the code before buying one I suppose....
Don't know how else to proceed now... :(
-
If only you were closer, I have a brand new GMsensor in my boot. :(
-
I'll go out and try again soon, just worried in case it was the cam belt and trying to start would make things worse, but knowones mentioned that so I assume it's unlikely it's that.
I know andy, I just seem to be to far from anyone on forum that could help.

Thanks guys hope it is just a sensor and nothing more serious. Appreciate all your help and suggestions. I know there's not much else you can do online. I have a mechanic coming to look at it tomorrow evening so hopefully he will be able to diagnose it then.
Cheers

Apparently its the crank sensor lead that breaks down, due to its proximity to hot stuff.
You could try locating the connector for it which is under the scuttle, then following the lead as far as you can giving a bit of manipulation as you go.
When mine failed to start 2 months ago and then again a week or so ago, this disturbing of the wire got it started. I still changed it, and so far no more problems.

Did that just last week. Started after turning over for a min or two
-
The V6 had EXACTLY the same problem / symptoms. The helpful chaps on here suggested it, wasnt sure it could be that simple. But crawled around under a scrapper, got a replacement, and bob's your etc, it was the crank sensor!
Never be afraid to try the simple stuff, it's often something trivial that causes the BIIG problems.
-
.... but knowones mentioned that so I assume it's unlikely it's that.
......
I did think of that, but I think you'd have had some metal to metal clanking noises to go with it. I'm not sure whether you can see any cams though the oil filler cap. They'd be stationary when the engine was turning over if the cam belt had broke.
-
Thanks guys, will keep you posted, I'm just lucky in a way as we have just purchased a yaris 1.3 SR for my partner as she passed her test a week ago so I will be able to use that to get to work in. Otherwise I would of been stuffed.
-
Ok guys, good news. Back up and running. After around 4 minutes of cranking she spluttered into life. He rekons it was the hydraulic tappets, happens sometimes apparently and shouldn't happen again hopefully. Going in for full service on Thursday. Fingers crossed it was a one off.
-
Well she started perfect this morning, still got my fingers crossed it was a one off.
Any comments as to if you guys think, hydraulic tappets is a good diagnosis? and if it is likely to happen again?

Sounds like 'dangle berries' to me, will happen again, nothings changed, except it's started this time.
Did he clear the codes? Please say yes...

I agree with Chris :o ;) complete 'dangle berries'. I'm still with my theory that it was started & turned back off when still 'on choke'.

Your 'Mechanic' should change jobs and sell pork pies instead of ripping people off telling them! ::)
As the other Guys have said, (and they are talking from real experience here) change your Crank Sensor before it leaves you possibly stranded! ;) :y
-
Well I really don't know what to say or think now, known the guy years and never let me down. He Is a Vauxhall mechanic. Isn't it even slightly possible that the hydraulic tappets can loose compression or lock or something that would cause the problem I had?
I had no engine lights on the dash at all once it started so I never thought to get the codes cleared.
Also I don't feel ripped off as he didn't charge me a penny for coming out to me in his own time, I know he didn't technically do anything apart from manually open the butterfly valves. While I was cranking the engine.
-
There must be any number of guys on here with 'good' second hand crank sensors, which are known to work, just lying around.
If all's well, and the cars running reliably, then you can go ahead and buy a brand, spanking new one, if you want, or stick with the 2nd hand one.
Either way it's not much financial investment to prove definitely it is or definitely isnt the sensor.
-
... Isn't it even slightly possible that the hydraulic tappets can loose compression or lock or something that would cause the problem I had? .....
It'd still start of a fashion on 4 or 5 cylinders, leaving any sticky 'tappets' tapping.
-
I take that as not then really. Hehe.
So it's running reliably now, all be it only 2 days and counting. If I get the crank sensor changed and it continues to run ok. How will I know it was the sensor. I suppose the only way is the leave it and see if it goes wrong again.
It's going in for service on thursday. Is it worth getting it on the computer to see if there is a crank sensor code?
-
.. Is it worth getting it on the computer to see if there is a crank sensor code?
If a pedal test doesn't show anything, then yes. :y
-
Will pedal test again tomorrow but was only giving 0100 the other day.
No objection to doing the crank sensor, even if I don't have any more problems. Just don't like not knowing the exact problem. ;)
-
Absolutely. But if you're anything like me, if there's two possible solutions, one costs a few quid, the other a few hundred, I tend to replace the few quidder, and cross fingers!
:y
-
Ok there were no other codes when read on computer. Had a service now too as it was long overdue. Running sweeter now will decent oil in it.
-
I am very much in agreement with the majority here - classic crank sensor.
It will likely be fine now until the most inconvenient moment possible and will fail with no warning (probably just refuse to start >:().
Strongly recommend you buy a new GM sensor and keep it handy (in the boot) for when it does let you down. (it doesn't take long to fit the new one)

Exactly right IMO. I had a spare and used it on another 3.2 with failed crank sensor...but a spare in the boot is highly recommended. If you keep an omega for the cars life, you WILL suffer a failed crank sensor eventually, had two myself, both about 130k miles as it happens.
And it's not feasible to fit a second hand sensor tbh, because removing the old one is not straightforward as it threaded through, and clipped to, the oil cooler pipes. To remove fully you have to cut the wire or remove the oil pipes by the oil filter and thread the old sensor wire out from that end, and who's going to bother their arse to do that with a fubar crank sensor? Noboby, if they bother to remove the old sensor at all....
If your anywhere near a tech2 then live data can be viewed on the cts apparently :-/, but odds are it won't see a failt until it plays up and won't start, then your going nowhere I would have thought. Vague on that theory though, a tech 2 owner could advise maybe.
If it was me though, buy a crank sensor, print off the guide and stick that lot in the boot along with a Jack. Keep pedal tricking for 0335 and hope the code comes, then fit the sensor.
As you say, if the sensor is just fitted blindly, then we will never know.
