Vauxhall Astra Running Problem

[oakdale]

I've been out of the trade for a few years now but I'm fairly confident this is an electrical fault of some sort.

The ecu has no way of knowing if the position of the crankshaft timing event is is wrong other than by comparing it to the camshaft position, and if this was in conflict it would show a cam sensor or cam out of synch code.

I'm sure the term out of range means a missing or intermittant signal, not that the signal is at the wrong position.

I'd be looking closely at ecu and engine earths.

The crank sensor fits on the front of the engine block on this, I think? There will be a reluctor ring - the part the sensor works with? If so, the reluctor ring is fitted on the crankshaft.

Is the new engine from an automatic car? If so the reluctor ring will be slightly different.
Also, remove the sensor and look into the engine and turn it slowly and look for any damage to the ring.

Hi there, I was reading the problems other guys were having with their Astra's and wanted to throw my g/friends car prob into the mix, hopefully someone can help. Its a 04 astra diesel 1.7 cdti.. Recently it has been failing to start after running, even very short distsnces , but will start first turn after sitting a while.
I'm not very clued up on mothers tho but I read these posts last week and thought it was a faulty censor giving wrong mix of fuel to engine as if it was cold. Does this sound like it could be our problem ? The fuel pump ect. Is fine and if I feed the fuel straight into engine it will start. I.e: today we drove maybe 2 miles, turned car off and 5 mins later it wouldn't start. Left it for couple hours and went back for it to start and drive fine.
Any help pls...

First thing to do is change the fuel filter.

No starting on these is usually the chip reader not reading the chip in the key, i have an 05 1.7 cdti in at the mo for a CIM change.
You need to get the codes read, read here for the easy (IE no code reader needed) way to read the codes and a list of the codes
