Hopefully, someone can help with this.
Yesterday my daughter went to supermarket . Shopping done she returned to car. Engine turns over but won't start. Flattened the battery. Good Samaritan helped with jump start but no go.
I got it started today by continuously turning it over and pumping pedal but it wouldn't tick over and kept cutting out repeatedly. Drove it to daughter house but it cut out 3 times at junctions in the 1 1/4 mile trip. That's in Cardiff, 20 miles from my home. So I need some ideas for tomorrow.

Speedometer flickers on turnover.
Glow plugs comes on and go off as normal.
Over half tank of fuel.
Haven't checked pleneum but cleaned them 2 months ago. Not had much rain in last 2 weeks.
Checked supply side of fuel filter . It's pumping out as I would expect.

Will check pleneum tomorrow.
Check ITB. UBP appears to be delivering.
I don't have any specialist equipment.

Thanks in advance of any gems of wisdom.
