Cranks but will not fire up.

[Fathearth]

Hi. Guys. Don't know if you can help but here goes.

I have a 2010 1.7 diesel Zafira and I have just changed the fuel filter. I have done this before with no problems at all. This time it cranks but just will not fire up and run.

I did turn the ignition on and off to prime the filter and there is diesel in the filter bowl but it just will not fire.

I have tried disconnecting the battery in case something needed resetting, but to no avail.

I have seen in other forums to tow it but that seems a bit extreme to me.

There are no codes stored.

I would be most grateful for any advice you can give.

Peter.
