Hi

Couldn't get the car to start this morning it just kept cranking but wouldn't fire. The ECU light was flashing about once per second so I figured it was a sensor problem. Right under the engine behind the splashguard was a White and blue connector that was full of oil from a leak I had a while back. I cleaned it out and bingo!
The connector looked a bit dodgy so I thought about replacing it or the sensor - but what is it? I assumed it was the crankshaft sensor but according to Haynes that bolts in by the oil filter and doesn't have an under-engine connector. This connector was up at the front of the sump by the timing belt cover.
Any body know what it is? If I go to Vauxhall they'll charge me 75quid to connect to a diagnostic before discussing the problem.
Thanks

Chris

Paperclip or pedal trick your car and see what the onboard computer thingy tells you

And if you use a paperclip to read any codes it`ll cost you bugger all

If the EML flashes then is usually an immobiliser fault no?

[Chris G]

"Paperclipping" and "pedal-tricking" I assume that means shorting out something on the diagnostic connector? Is there an idiot's guide somewhere? Thanks

Ah-hah! Fault code 19 three times in a row. Looks like it is the crank RPM sensor after all.

Excellent, can't thank you enough. I love neat tricks like that which prevent me getting ripped off by dealers!

Off now to google replacement sensors!

Word on the street is to buy genuine Vx only direct from Vx as aftermarket (even 'OE') sensors have a habit of failing again in a matter of months.

[davethediver]

As said genuine vauxhall only, straight from the dealer not ebay

[Chris G]

I hear what you're saying re genuine sensors, and I've now located mine and know what to look for. Thing is, the connector I cleaned out to get the car going isn't connected to the crank sensor at all. I'd like to replace both the crank sensor and the offending connector, which looks old and dodgy, but I still have no clue what it is!

Anybody recognise the white and blue connector in this picture, as I still think it's involved in my problem?

[aaronjb]

That looks like it's probably the mag clutch connector on the a/c pump to me (could be wrong, someone will confirm in a moment I'm sure) - in which case I can't see how it could be related to starting the car at all, and I suspect it might have been coincidence..

[2woody]

certainly is. That's the connector right at the end of the chain of switches that turns on the air conditioning.

I fail to find any reason that this could be connected to the non-starting

[RobG]

Yep, as above, it`s the connector for the A/C compressor clutch

[Chris G]

Hmm

Must just have been a coincidence then.  Thanks, that's saved me following a dead end.
