it starts ok when cold but not like it used to be. When its hot it turns over for ages b4 eventually starting or on a bad day it wont until its cooled down.Its doing my head in could it be a temp sensor? how many temp sensors does this van have... had a recent fuel pump ecu and battery and starter.

i'd go for the crank sensor

has the fuel filter been changed recently?try a scrappy for crank and cam sensors and try these and maybe give the egr valve a clean,worth a go,good luck
