Vauxhall combo 1.7 DI

I will get it checked for fuel bleeding back. The van is always parked over night nose down on a steep slope.

A diesel engine needs cranking speed to start it, especially in the cold , if the fuel is draining from the pump you will lose the best from your battery after around 30 seconds cranking depending on the amp/hour capacity .
Try what I have said -nothing to loose.

Sorry I was typing that as you posted.

Poss perished spill off pipes. ..Black rubber on top of injectors. ..can start to let air in and causes pain in the rear starting issues

 

[overskilled]

Could also be bad meg connection to starter..easy fix...add a ground strap between battery neg and starter neg post

 

[overskilled]

Also unplug the EGR electrical plug...If it starts better then EGR isn't sealing properly

If you've got the fault codes (and their meaning) then start from the 1st one. The 2nd, 3rd ,4th etc may have nothing to do with the fault. If 1 sensor isn't working properly (eg. not sending a value to the ecu) then the ecu flags up a fault, other systems on the vehicle also rely on that value for them to trigger, no trigger and the ecu flags up a fault and so it cascades. This is from experience, Landrover wanted just over £1000 to rectify all the faults, so I did it myself. 30 minutes and some scuffed knuckles later no fault lights and it was running perfectly. And all because a wire to a wheel speed sensor had chaffed through.

Injectors??

I had a combo that I had intermittent starting issues with but like you once it was warm it would start every time. A bottle of injector cleaner and I never had that problem again.

The leak off / spill pipes may also be used to prime the fuel system if these are shot then you will struggle to start it

What fault codes are showing? Due to the cascade effect some fault codes are red herrings and can mask what is the actual fault

Hi,These engines have a well documented set of issues,that a quick trawl of the GM forums will enlighten you.

If there is any discrepancy between crank and cam sensors,or even not coded to show,check cam timing.

Chains jump,tensioners fail,and the drive sprockets are locked up by clamp pressure only,no keys

Them old Bedford HA vans never suffered from this...:conehead:
