Just a chance that an air filter change may help.

Wasn't a Cab but a diesel Galaxy I had many years ago was the same symptoms. Air filter blocked with leaves (and powdered leaves) so a simple filter change sorted it.

The filter is absolutely filthy,put a new filter on today,there's a hole on the filter box personally i think there's a bit missing,as it's just sucking in air and everything else!

What make/model of vehicle ?
Sounds like it may be the turbo if it has one, or a split in an air hose. The symptoms point to some sort of air intake problem, turbo, hoses, mass airflow sensor, filter.

Let us know how you get on, might help others to know.

No it hasn't fixed it,drives really flat as if the Turbo is not kicking in, had it on diagnostic machine and these codes came up,It's a Tx2 2002 it's beginning to Stall occasionally, engine noise changes just before it stallls as similar to an exhaust blown re start it and drives but still flat as a pancake.

P1666 injection pump control module
P0149 Fuel Timing Error
P1563 Injection Pump Control Module requesting engine stop
P1564 injection pump control module requesting reduced fuelling
P1664 injection pump control module malfunction
P0335 Crankshaft position sensor A circuit.

Any help Appreciated

I would start with the cheap and simple. I would change the crankshaft sensor. If this is giving a false reading that could explain the timing error.

A crankshaft sensor is only around £15. The fault codes seem to suggest a problem with the injection pump or control module but the problem may lie elsewhere.

If there's not enough air getting into the system the pump control module will sense this and throw out the error codes. I'd start by making sure all hoses are attached and there's no cracks or splits in them, then change the crankshaft sensor, then swap the mass airflow sensor, then get the control module checked and finally test the injection pump. Try each in order and see if the problem goes.

I had a split in a turbo hose and it went to about 50% power.
When my injector pump went the engine would cut out if you floored it or tried to go above 60mph and the coil light would come on, but it had done over 300k miles by that time. Unlikely for the pump itself to have failed unless a very high mileage, more likely for the control module to fail.

Thanks for all the advice guys appreciate it, I've changed the crankshaft sensor,changed fuel filter,cleared the codes drove lovely for a short time then went back into limp mode,put the diagnostic machine back on and the same fault codes came up as listed above,

Cold start takes a couple of attempts after that it's fine,just runs really low on power.
