I have seen many issues with the fuel primer pumps. if this id a direct inject motor then its the plunger on top of the fuel filter, if its a common rail engine then its a plunger in the fuel line under the fuel filter.
when temps are hotter then the fuel will expand more and can draw air back in through the primer pump when contracts again. best way to check this is to fit a clear hose between the outlet of the fuel filter and the engine, then drive the vehicle to get the fuel into normal flow then park it in the sun and leave it. later on check the clear hose, if there is no fuel in it then air is entering the fuel line somewhere, most likely from the primer pump, if its a hose then a fuel leak will been seen.

SOURCE: wont start when hot!

hello there, wow my dream p-up. nissan pathfinder 4x4,  unfortunately i have to settle with my nissan navara truck. anyways, the possible problems would be the injectors and injection pump. injectors are really direct on the combustion chamber so everytime the engine runs it is severely exposed to very high temperatures. the nozzle tips are the ones very much abused. the injectors have 2 seals. the first one which hugs the body of the injectors which is usually made of hard copper and the 2nd is called the chamber washer which is a stainless steel type concaved washer which serves as the nozzle tip seal and heat nozzle tip heat dispenser. if the nozzle tip floats there is a tendency that the tips are flame red due to heat thus, diesel is boiling to the point of turning to vapors enough to push the remaining fuel back to the injection pump when you shut the engine. then the one way valves of the injection pump comes into play. the valves might be weak and due to the high pressure, fuel slowly creeps back into the pump body. hope this helps.

SOURCE: nissan patrol 2.8l no diesel to the injektors

to test the engine correctly you will need to buy or rent a NOID test light to hook into the injector rail leads to insure the computer is sending a pulse to the injectors if there is no! pulse or signal while cranking the the ECM has gone out . if there is a pulse then check the filters for water contaminents and air locking the secondary pump needs to be checked for pressure and internal failure as well also check the fuel check valve in the main injector pump for sticking shut as well those are the most common failures to that engine also on the main pump check the voltage at the injection pump to insure there is 12 volts with the key on

Nissan patrol 4.2 Diesel engines where lightened in 1994black rocker cover has it weakened enginewhat parts where changed


you make little sense in your statement
define clearly -- lightened in 1994black rocker cover has it weakened what do you mean with this
also It probably should have had a turbo originally
talk with nissan about that but you can fit the turbo to the engine provided that it is of the recommended capacity for that engine

turbo retailers will be able to help you with the correct unit to fit

Why won't our 2009 nissan patrol common rail diesel start when hot


Give me a bit more info, like does it actually start when you pump the pedal? Is it only when its hot/cold or all the time? i just had the same problem with my 09 nissan patrol. We tried the fuel pump which was in good nick holding correct pressure. Then tried a compression test which came back all good. Problem was the injectors. Replaced them and all is good. Expensive though at 800 bucks. Try injector fluid if you do actually get it started, hope it helps let me know how you go.
