Isuzu tropper 4jx1

(whoops - hit the enter key by mistake) .... beyond the harness join (where the oil level / oil-filler located) so you can rejoin later and this will cut the reading to the ECU and will give standard "Limp home" running. Check for oil in the wiring and plug also as this can add to your problems). If it runs ok like that you will have to replace the ORPS sensor under the tappet valve cover. Use only MAP sensor cleaners NOT carby cleaner or others as they will create problems dissolving plastic that you need for insulation etc. The white wire may look yellowish after some years under the bonnet. These are common on newer vehicles but there are more testing systems in place now that will put up error codes for what we are experiencing. The valve cover job takes time but not too difficult. Make sure you seal the wire cable semi-circular gasket under and on top and within and beyond each side of the injector (pink) wires to stop oil leaking out in a continual stream of drips under the vehicle down the left side of the engine block. Get Ultra Blue and save messing with gaskets also. Have fun and build in a valve adjustment if you need one when the cover is off.

Just a quick point - there is NO injector pump like the old diesels. The 4JX1 uses a high pressure oil rail (or tube) under the valve cover to hold high pressure oil. This is injected into the injector and multiplies the pressure to around 27,000PSI to pressurize the diesel fuel. Pretty nifty but poor injector seals created havoc and eventually were replaced under recall in most countries by so called ceramic seals for critical o-rings within the internals of the injector. Mechanics who are looking to replace an injector pump may be somewhat off track. (Being very politically correct here. Just a quick point - there is NO injector pump like the old diesels.
