I have a 2.2 diesel estima i have a problem of starting my car i have changed the glow plugs and tested glow plug relay and changed the fuel fillter when it does start white smoke comes out but clears after it warms up a bit . i no that the turbo rear sill has gone so have oil around the turbo area .would this stop the car from starting if the turbo is nackerd ? but its like the fuel aint getting into the cylinders i have taken the injecters of from the fuel pump to check fuel is coming out of the pump and it does can anyone help?

There can be several reasons for this. The cheapest reasons to look at are spark to the glow-plugs and fuel to the cylinders. If you have a "ready light" on the dash that tells you when the glow-plugs are ready, you need to listen for the clicking of the glow-plug relay and the blinking of every other light that is on in sync with the clicking sound.
If the clicking and light dimming is not observed your power relay to the glow-plug relay is probably bad. A voltmeter will be needed to test for juice passing through the the power relay. If you have juice going to the glow-plug relay from the power box relay and it does not cycle off and on, your glow-plug relay is bad or the glow-plugs are bad.
You can test the power to each glow-plug with a test light or meter (when the power relay and glow-plug relay are cycling). Glow-plugs are similar to spark plugs and they can be tested. It can be tricky or you can just replace them.
Fuel, this time of year is subject to freeze-ups. Additive will help, noting Diesel additive and NOT gasoline additives. In short, Pyroil makes a starting fuel which has protective oil in the spray to help the cylinders. A spray of starting fluid will diagnose that fuel starvation is the problem. It is tricky to use when the glow-plugs are hot. On injector systems with O rings the cold weather can sometimes cause the O rings to shrink when sitting and leak. Your fuel will run back to the tank. Cranking will not be enough to draw up the fuel. Another way is to change fuel filters BUT to put some diesel into the fuel filter to prime the system. No guaranty that the problem will not reoccur because you have not permanently fixed anything. Hope this helps, if not then something has let loose like a fuelpump.
Have a load test done on the battery as the glo-plugs should get very hot very quickly. Diesel engines have to have a high rpm crank speed or they will not start and will leave unburnt fuel in the cylinders ( wet glo- plugs). Every indication is that the battery is flat or is not the right capacity for the car.
fuel at fuel filter doesnt mean its getting the correct pressure to operate the injectors. do not spray starting fluid into a diesel motor, you will damage the rings, score cylinder walls, burn valve guides... etc . starting fluid is not designed for diesel engines. the only way to test the fuel system is to test it by hooking up a pressure test gauge to the service port. the next most likely issue would be a faulty glow plug relay or 1 or 2 faulty glow plugs.
Your glow plug relay is located on the top of the
engine on the right side toward the front. Some models there are 2 solenoids. A
large one toward the front and a smaller one right behind it. The glow plug
relay is the smaller one toward the rear. The larger front one is the intkae
heater relay. To test the glow plug relay turn engine to on. dont start it.
both of the large terminals should have power with key on. then turn engine
off. only one large terminal should have power. If when you turn engine to on
you only have power on one side then go to this test. Turn engine on and test
smaller wire. it should have power. If it does replace the relay. If the
smaller wire does not have power you have an ignition problem or power (wiring)
problem to the relay. Also note the engine needs to be cold. If temp of engine is over 130 the computer will not turn the glow plug circut on! Most of th time this is what fails and not your glow plugs.
Hi, glow plugs does not need changing unless the vehicle struggles to start in the morning or when cold. When testing the glow plugs, they should not take longer then about 5 seconds to become red hot.
The glow plug relay is responsible for the duration of glow plugs, this needs to be the starting point. You should get a 12v out for so many seconds when ignition is switched on.
I have taken the cover off relays in the past, cleaned up the internals, sprayed with circuit cleaner and got plenty more years out of them, worth a try.
