2007 Combo Van, 1.7CDTI

Went shopping this morning, on returning to the van it would not start, it turned over OK but showed no signs of life. I have breakdown cover so I waited for them to show up (90 mins) he tried some easy start, he says it looks like it's a no fuel issue so cracks off an injector (fuel connection) and only a dribble of diesel is seen during cranking so he diagnoses an injector pump failure.

Has anyone replaced this and is it a difficult job? new, or second hand hand part? as the van is not wort a lot.

Thanks for any help or suggestions.

I think you need to get a proper diagnostics done before you jump in.
As it's a CDTI, it's more likely to be an electrical problem rather than the pump.

So I did a diagnostic check today:
VAUX-COM

Corsa-C > Engine > Z 17 DTH
Total number of fault codes: 1

P0380 - Glow Time Relay Circuit Malfunction
(02) - Not present


No other engine ECU codes were present. The code seen has been showing up ever since I purchased the van four years ago.

The van has always been a great starter in the COLD but is sometimes harder to start when the engine is hot, it's had a new starter motor and battery within 18 months.

Does this now point to a faulty injector pump (BTW is this a Isuzu or Vauxhall engine?)

So today I did a further test with Vaux-com in 'Live' mode (recorded)

I used the 'Measuring Blocks' button to find the 'fuel rail' section, started 'record' and observed the results during cranking the engine. I noticed that the pressure at line 64 (seen below) was 35.8 MPa.

I was surprised to see when I looked at the recorded value for the same line (64) was only showing 0.67 MPa, maybe someone can explain the difference between the observed and the recorded value.

During the test the engine still refuses to start with NO signs of life.

Can anyone tell from the results seen below a cause of the non starting problem (I have the full live data file if needed)

Thanks

Results obtained at engine cranking speed

Post the csv recording,.. does this have an intank pump, if it does is it working.
Here it is, readings obtained at cranking speed.
I don't know if it has an in-tank pump.

Do you have the actual .csv file. To me it looks like it never recorded anything other than ignition on sensor status.
I scrolled to the 'Common rail fuel pressure' of the 'Measuring blocks' section and recorded from there.

Yes but the picture above is just a snap shot of that recording, where is the rest of the data, if you cranked for say 10 seconds then the recording will be ten seconds long, this just looks like ignition on data, have you got the recording or no.

I'll do it again today and post

For whatever reason there's no fuel pressure,that engine doesn't have an in-tank pump
