Try a compression check of every cylinder. A blown head gasket could be the result. 1. Remove the coil wire. 2. Remove a spark plug wire and plug. You should do 1 at a time. 3. Install a compression gauge. 4. Have a second person crank the engine until the gauge is at the appropriately rated pressure and write it down. 5. Do this with each cylinder. 6. Compare the readings on each cylinder. Every cylinder should be about the pressure. Of course engines with a lot of miles can normally have a little difference in pressure,but not too much. The one with the lowest reading could have a bad head gasket,resulting in overheating,and hard starting.

My Isuzu Bighorn 4JX1 RJM Engine stalled after fitting it with new oil pump. It can crank but is emits smoke but not run. What could be the problem? I have tried to check if the fuel pump is not working...

the engine oil pumps are in the rear of the engine(trans out) and behind flexplate /flywheel, were any of these 2 engine oil pumps touched if so the flywheel /flexplate has to be timed to crankshaft position, so you might have it in the wrong position, if your talking about the diesel lift pump (injector pump) that also supplies high pressure engine oil to injectors, after replacing this there is a learn procedure for the rail pressure control valve that is on pump. this can only be done by dealer or some one with Tech2 scanner tool.

White smoke is usually a sign of coolant burning. Carefully open the coolant cap, sniff the inside. If there is an exhaust smell you more than likely have head gasket problems. A further diagnosis is needed to be sure. Also ensure that any wires/plugs are reconnected. If the oil sensor is unplugged the vehicle wont start.

Isuzu Trooper (Bighorn) 4JX1 Engine Common rail injection. Year of manufacture1999 We have problem with this vehicle. Refused to start for about one year. Parked in workshop that period. Sent my guys to...

Try fitting a seperate transfer pump between the tank and HP pump(quick/cheap fix only) and see if this resolves the problem. If yes check filler cap(no air lock), air leaks in supply hoses or transfer pump(and of course the usual "check the fuel filter").
If not, dig deeper:

J-1-15(not indicated) : Earths glow plug relay to enable glow plug circuit.
ECM : Electronic control module
IS : Idle switch
ECT : Engine coolant temp
OTS : Oil temp sensor
IAT : Intake air temp
FTS : Fuel temp sensor
INJ : Injectors 1 through 4
RPS : Rail pressure sensor
EGR : EGR vacuum pressure
MAP : Inlet manifold pressure
APS : Accellerator position sensor
