Isuzu Trooper 3.0D DOHC 4JX1 CAN''T START AFTER REPLACING FLYWHEEL Three weeks ago I replaced the faulty dual mass flywheel with a second hand but working one + Diesel and oil filters for engine and Turbo. From then on the 4JX1 engine refused to start. An expert mech. checked the flywheel sensor and declared it fit, still he could not start it. It cranks and produces all the signs of attempting to start but fail to. Did I overlook something? Can you please help out?

you need to set the timing to top dead centre and the flywheel has a little knotch in it set that at 6 oclock will start then you need to set the timing to top dead centre and the flywheel has a little knotch in it set that at 6 oclock will start then

Hi Sir Cleme, I cannot remember any sensor being on the flywheel of the 4JX1 engine, but I do suggest you check the crankshaft and cam shaft pick up sensors. After checking those sensors make sure you have evacuated all air from the fuel system.

the crankshaft has a timing mark on the flywheel. so u might have installed the flywheel incorrectly...u will have to pull down the transmssion again and try re-timing it..be sure to locate the mark, im sure this will solve the problem the crankshaft has a timing mark on the flywheel. so u might have installed the flywheel incorrectly...u will have to pull down the transmssion again and try re-timing it..be sure to locate the mark, im sure this will solve the problem

Hi again Clem, Just read this comment. Sorry Sir Clem, The crank and cam sensors control the injection working in unison with the O.R.P. Sensor. Make sure the battery is turning th engine at the required speed, as a depleted battery will turn the engine too slowly for the signal from the ORPS to open the injectors. Also keep in mind that the engine is a common rail injection system, meaning that once pressure is released from any injector, all pressure is lost. Use of the incorrect engine oil can damage the ORPS and result in a refusal to start. Regards John Hi again Clem, Just read this comment.
