Oh you must be in Canada or overseas? We don't get this vehicle in the US, so I don't have a database on it.
Generally, on modern diesel the injectors are controlled electronically by a direct injection module. I think the only way to diagnose this is with a scan tool.
So can you momentarily start the engine with a squirt of starting fluid? --use very sparingly on a diesel---I'm only asking so that you can double-check your original diagnosis--it should kick right off with starter fluid.
If it doesn't start, you might check your glow plug circuit.
#159 of 166 Motor rums good but smokes bad
Oct 15, 2010 (12:02 am)
I need some advice.I have a 1989 timberjack logging skidder with a 4 cyl.cummins motor.The motor runs good and will pull a heavy load, wide open but when you let off the gas it smokes bad !! The smoke is whiteish with a strong smell of oil,but does not use any oil,and when it idles after it is hot the motor will start to miss a little.Could it be the turbo,or the head or maybe the rings.And how can I test it to see which.I would be grateful for any help.

Need a bit more info. How many hrs. on unit? Put your thumb on breather tube, should not feel over 8 - 15 psi air hose. Valves adjusted lately? Check exhaust port manifold temp with infrared temp gun...20*F +/- max with each other. Use temp gun at coolant outlet neck...195*F-230*F operating temperature. White smoke probably is from non-combusted fuel-if engine temp is ranging 130*F - 150*F operating temp this condition can occur. If low temp,check t-stat(opening to soon).

Truck is building pressure in radiator and pushing coolant into overflow jug, then out of jug on ground. I replaced thermostat and radiator cap, still have same problem. The factory temp guage has never showed hot. Any suggestions ???????????????

Gauge could be wrong. You might want to get a radiator thermometer to double-check. One thing that drives people nuts with diagnosing overheating issues is making assumptions, such as relying on the gauge, or thinking that because a part came new out of the box, then it must be good.
If in fact you aren't overheating, then you might have a clogged radiator. Have you ever put a stop-leak product in it? That'll do it.

I have chevy 2500hd with a duramax that is giving me problems. estimates to repair are 7500-9000, wondering if I can change it out and put a gas crate motor in it for less. all thoughts are welcomed

Appreciate the advice, but since then it has began smoking white smoke out of the right exhaust tailpipe. I drive a big truck for a living and when they do this, it usually a blown head gasket. Of course it still has pressure in the radiator. I'm 99% sure it has not been hot. I checked the water temperature with a laser, and it shows around 190 degrees. What do you think about the head gasket "assumption" ?

You can buy a test kit to test for combustion gases in the coolant.
