My D22 pick up has problems accellerating in the 3rd and 4th gear. We checked turbo and a lot of other things without solving the problem. Now I was told it could be the diesel injection pump. Can I c


When there is acceleration problems with diesels it is because there is low torque occurring in that particular rpm range. ( incorrect fuel metering) If you have verified that the turbo is operational then it will be a governor problem in the fuel pump or worn out pump. If it is a common rail diesel the run the fault codes or have an accredited diesel specialist shop check the program in the CPU ( may be corrupted). Blocked or faulty filters will give an indication under heavy load when there is maximum fuel flow required. If it is a rotary pump or in line pump I would be taking it to an accredited diesel specialist and have it properly assessed.

Have you checked the PCV system?? If its stuck in the closed position then you will lack power and turbo boost. A vehicle needs 3 things to make it run proper; FUEL,FIRE and AIR. Try that and see if it helps.

Hi I have a Nissan Navara turbo deisel 2002 model it drives for approx 50 minutes country driving then dies, I wait for 1--2 minutes and it starts up and drives off as if nothing happened only to do i


2002 is common rail with all fancy electrics and computers and stuff like that ,now this makes it very difficult for this old fleet fitter who used to repair diesels with nothing more complicated than a vacumn controlled speed govenor ,where we used to re-calibrate the injector pump on the vehicle .I think this fault is either something simple like a plastic bag in the fuel tank that gets caught up in the pick up pipe ,failing which its a complicated electronic issue of which i confess to knowing nothing about

MY 94 rodeo 2.8lt turbo diesel blows lots of smoke when the throttle is down.. When i lift the foot of it stops smoking.. can you help..


if its black smoke and id say it is being a deisel it can be injectors or just simply fuel pump timing. get it to a deisel specialist to check the pump timing and your fuel load under acceleration, only real way to get it sorted.

The Turbo Charger does not seem to engage .I was led to believe that after around 30 miles per hr. it would be like haveing a passing gear. Oh yes the car is a 1984 Nercedes SD 300 series Desiel.


The turbo charger has more to do with rpms than road speed.The turbo uses exhaust gas leaving the engine to push more fresh air into the engine thus creating higher compression and more horse power.You should feel some boost above 1500 rpms if everything is working properly.If not then you should have the system checked by a dealer or a good diesel shop.Good Luck!

Check your TPS Throttle positioning sensor. Sounds like it has a dead spot in it or it is failing. May also be a wiring harness issue or loose connection at TPS too! If its intermittent then it will soon go out completely. It should be located on your fuel pedal. Remove it and check it with an ohm meter. Check resistance all the way thru from 0-100 percent. When it is not working it should do nothing and show no resistance. When it is working the resistance value will increase and or decrease as you turn the sensor.
