Title: 2001 Omega 2.2 DTI diesel started > stalled > will not start
Post by: Darius on 22 December 2019, 16:52:00
My 2001 2.2 DTI had been sitting for a day or two.  I started it and moved it 50 yards - no problem.  An hour later I started it - no problem.  I moved off and I stalled it.  It then refused to start.

I cranked till I eventually flattened the battery.  I recharged the battery and tried the next day and it was exactly the same.

It has 1/3 tank of fuel. The glow light comes on as normal when I turn on the ignition.

I suspect fuel starvation not least because some years ago the fuel return pipe developed an air leak which emptied the fuel pipe.

Does the diesel fuel pump have a fuse?  I ask because the manual says Fuse 18 is for the fuel pump but there is no Fuse 18 inserted - the position is empty.  I wonder if Fuse 18 is for a petrol pump and so unused on a diesel?

Does it have a fuel cut-off switch?  If so stalling it might have given it a high g shock which tripped it.  The manual does not tell me it has one nor how to reset it.

All the fuses in the fuse box close to the battery are good.

Any thoughts will be appreciated.

Thanks.  All the fuses are OK so I am beginning to suspect the relay for the glow plugs or the fuel pump.

It was the fuel pump which had failed.  It got a new bit of electronics and all is now well.

The EDC failed, common Bosch VP44 pump fault :(
