Would it be possible/plausible to swap the ecu / gauge feeds from the temperature sensor over ?? That way you "might" a) solve the problem if the normal gauge side is working properly b) actually "see" the problem if the ECU side is not working by now action on the gauge ??

No idea if this would work, but without the ability to see live data it strikes me as a possibility ??  either that or is there someone close to you with a code reader capable of live data ??  North Wilts is a tad far from Rhyl or I'd offer !!  ..... 

To be honest I'd be just as happy with the part numbers I've requested as looking through all the history these parts have never been changed. They don't last forever.

Thanks

they're also unlikely to be the cause of the problem. But it's your money. And time.

So a crank sensor when warm can't start to breakdown and cause starting issues. I think you'll find they can when they start to fail.

The ecu coolant sensor failing can't cause over fueling by telling the ecu that the engine is cold so give extra enrichment?

You're really helpful aren't you. I've experienced both these problems before.

I agree with the lambda sensors. But since there's no record of them ever being changed I'd like to do them anyway.

There's always a keyboard hero isn't there.

Those could be faulty. But just changing them in the hope that it will fix your problem is inefficient and expensive when you find that the fault is elsewhere. There's a reason some basic diagnosis is our first recommendation. But as I said, it's your time and money.

Hi Nick W

Sent you a PM can you let me know if you got it and able to help either way

Thanks

Have you done any work on the engine which resulted in unplugging everything at the back of the block

If yes, then you might have swapped the purge valve and ecu coolant temp plugs... They sit almost alongside each other and have the same type of plug. Only issue is that the purge valve is 12v whereas the coolant sensor is 5v...

Run it upto temp, then switch off. Attempt a restart. Then remove fuse 18 in the cabin. Does the car now start? If yes, then you need a new ecu coolant sensor. If no, then it's summat else.

BTW, Nick is usually spot on, so for a year old newbie with 66 posts, you're jumping to alot of conclusions

Hi i agree with DG,Nick is only trying to help mate.Dean.
