Don't start after oil change

I have a 4jx1 trooper. it cut off after oil change. I open the angine and change rings. Everything is new but the injectors. The mechanic put some 15-40 oil in it. It doesn't start. What else can I do if I can't get the Tech2?

    I take it this vehicle is a diesel? If so you need to use the correct grade of oil as recommended.

4 jx1 motor stop running after oil change. Flush engin and and get it started for short while, flush it again and run for 5min. Change the oil (5w30) and dont start. Clean the injectors in ultrasonic bath and got it running for 3 min. Now its dead, look like a funeral.

I HAVE A TROOPER 3.O L THE SAME AS YOU AND I KNOW THAT WHEN CHANGING OIL YOU MUST USE 5-30 OR 5-40 FOR THIS ENGINE REASON BEING IS THAT THE OTHER GRADE DOESNT CREATE THE SAME OIL PRESSURE AND IF THE OIL PRESSURE IS NOT CORRECT THESE ENGINES WILL NOT RUN BEEN THERE DONE THAT

Rail oil pressure sensor is the one to check first ,buy the engine oil dipstick is a electrical connector with all pink wires going into the engine but on the other side will be one white one maybe looks a bit yellow , now pull this one wire out and see if you can start the car ?

If starts good the sensor is faulty but dont drive like this its only a test ,get a new sensor.

1999 trooper 4JX1 fuel black


engine oil leaking past injector O rings and going into fuel return hose back to tank contaminates tank. if recall done are O rings ok? can put clear plastic tube on return fitting in rear of head to see if black (contaminated with oil) or air leaks, from cold start, it isnt high pressure
it could be from before or now?

4JX1 engine cut off while test drive after oiland filter change and not starting


That pop noise is ok just the flap in the throttle body coming open when the car stops .
The engine may have stopped because its low on oil so the oil pump for the injectors wont work - takes about 7 u.s. quarts of 5/30 fully synthetic oil at service time to run right.
It can also stop if the pressure sensor in the injector rail packs up or the oil pick up pipe for the injector system falls off due to cracking the mount .

Fly wheel problem on a jeep


if its a 4JX1 diesel, yes it goes in 1 spot yet it can be bolted up in every location
put crank pulley timing mark to TDC can also check by removing cam belt top cover and check timing mark aligned up with mark at 12 O clock then flywheel has small notch in edge that must go at 6 O clock (facing down) look closely it is hard to see due to flywheel sunk into back of block.
