1997 patrol.GU?
has it got the older engine with the throttle cable--or later GU with flybywire.
early models look for turbo boost presure-exhaust restriction as turbo often fail.then if you had the pump checked--did you check the injectors as they are not long life.
fly by wire has a computor with a air flow meter.
if it fails the engine will be in limp mode above 2500 RPM.
if any imputs fail it can cause alsorts but the system is easy to fix whith a consult scaner required.
