Weak battery or problem with getting the fuel pressure up?

[CaptainSlow337]

I had the same issue a while back, fixed by replacing fuel filter.

ok.. batteries 3 months old... fuel filter was replaced 3 weeks back and iv just run some diesel purge through it.

Al.

If it's not filter and not battery then the next on the list is insufficient cranking speed.
This could be a simple as a bad earth strap back from the block ( they tend to go just at the lug under the starter) or a lazy starter motor. A jump lead bypassing the earth strap might show it up provided the lead gets good contacts.
Have you any class of a reader that would show cranking speed?
