2005 Navara d22 zd 30 Hard to start

Were the codes cleared after the new battery and crank angle sensor were fitted to see if it throws new codes?

injector pump?

If it cranks slow AND you have a new battery, the only pieces left are the leads and connections in the start cables, (never big enough even when new). Made to a minimum spec.
While cranking a decent mechanic will check for voltage drop across each cable run before replacing starter motor. However it could be the starter very dry in it's bearings or poor brush contact.
It seems no one these days ever removes and services starter motors and cleans and lubricates them with decent lube oil and grease in geared sections.
If you do it makes and amazing difference if lube is the problem.
If the starter is sound but dry it is cheaper to lube a starter than buy a new one.

After that is functioning correctly other problems may not be there.

hi
I feel your pain .
I have a FORD Ranger 3.0lt with the same fuel system . I have also a poor starting . rough start or no start
Battery check
Injector bleed off check
check compressions
Rectify all codes ,some codes are only a symptom of problem
check for blown head gasket
Pressure relief valve bleeding off excessively ?? / bench test pump
check contamination in tank
check tank breathers
check for bubbles in fuel lines [at primer]
check fuel /air leak engine fuel lines

Thanks everyone for your input.The new starter did the trick.As soon as you hit the key it starts.You don,t realise how slow the old starter motor was.Cheers

Starter motor taking too much power out of the system, very common,new starter
