Hello and Welcome to justanswer...
My name is MIKE - the previous expert appears to have opted out of helping you here..
Given its been coded - and you still have the same issues - your problem is one of four things -
Either - - a fault with the pump (still )...or injectors...(still)..
Or - a programming fault..
Or- a fault with the wiring / circuit -
Or - a fault with the PCM.
It will be one or the other as above -and all needs to be checked.
Start with verifying the pump and injectors with the suppliers / fitters ... and go from there..
If you get past wiring - then the next step is to have the PCM sent to a Ecu test / repair company as its a specialist job - using special equipment that garages dont have.
You can find these companies advertising on google and the like -
SO work through as above on this one to get to the bottom of this now.
Im very pleased to have helped you -Let me know if I can help anymore...
