Question about Isuzu Trooper
In the plug by the dipstick are the pink wires going to the injectors but one will be white/yellowish on the car side - remove this wire from the plug to see if the car starts then the rail oil pressure sensor is at fault because it may read ok but the car dont run !
Anti theft light goes off when cranking thats ok but the reading for the rail oil pressure control valve is important in a no start problem does it rise when cranking ? should be about 18-25% if it goes up to 90% then the lower oil pump is starved or pulling air or the rail oil pressure control valve is suspect,wants pulling out to see if its ok .

Things to get checked
is there oil in injector harness connector near intake throttle body?
if so rail pressure oil switch and loom need replacing. can see reading from this switch on tech 2 data display and compare reading with desired reading also check this reading while engine not running (should read close to zero) 0.02Mpa normal if any higher while engine not running it can be problem.
have you had any injector repairs or recall done recently?
have had faulty new injectors and also leaking injector seals/seats (bad workmanship from repairs done) this is a very tricky procedure
and new injectors need code programmed into engine ECU.
another thing that is common now with a few is crank angle sensors and wear in crankshaft thrust bearings (it looses crank angle senor signal and stalls especially manuals when you put your foot on clutch they stall when cold)
can check for RPM displayed while cranking with tech 2 (230-280RPM)
