Question about 2008 Mazda B Series Pickup

Mazda BT 50 3.0L injector problems

The vehicle will start when pushed and run for a while, fairly far if you are not too heavy footed, but will not start off the key. There is no diesel coming out of the injectors when the engine is cranked. The fuses are all ok. The agent, 2000kms away, says that the high pressure pump and injectors require replacing - very costly and as I am in a country not covered by the warranty and it looks like I'm paying. The vehicle has done just over 40 000kms. Not a very good example for Mazda if I have to replace the pump and injectors. Help please.

    This is a common rail system and, as such, does not have a conventional inline or rotary injector pump. Incorrect pump timing would not prevent fuel from being injected on cranking which is the main fault at this stage. Ergo, heater plugs.

I don't think there is any problem with injectors but the cause could be pump
just loosen the pump bolts a little bit so that you can move the pump with leverage to advance
check the heater plugs as well

    as it is CRDI check for the supply to the injectors

    when the ignation is ON it should positive direct & negative on cranking get it checked with test lamp

I have a mazda mpv 2006 2.3l turbo from japan.2 months of using the car its smoking and oil level dropping ever day


If the vehicle has a diesel engine and it starts with black smoke that clears you should put some injector cleaner in the fuel tank, a couple of treatments should clean the injectors.
If the smoke is grey/white perhaps you should have the engine checked for issues.
If the vehicle has a petrol engine maybe the valves need some attention.
Ideally you should have the people who supplied you with the vehicle take a look at it . The problem wit himports is that some elements of a vehicle need modification to run correctly, this sounds as though something more serious may be ammiss
The oil level is reducing quickly, that needs investigation.
I would say that the person who supplied you with the vehicle needs to take a very close look at the engine.

GOOD LUCK WITH IT

Mazda bt 50 problems


If you still have 25 lts still left in the tank and get it out. I would think the pick up tube is bent or cracked and no longer at the bottom of the tank.

Mazda bt50 deisel. Sometimes it will start, other times it will not, but will start by pushing or doing a rolling downhill start, would this be the solenoid controlling the fuel flow. Please...


Just had same problem myself. Very expensive one too.
Contaminant appears to have gotten through to the injector tips and damaged the injector nozzles. Was told by mazda it is water in the fuel. Injectors are very expensive an I replaced 4 and all was fine until 1000kms later the same thing happened. Totally ruined our holiday to Cape York in Australia. Mazda say they are now waiting to get new high pressure steel injector pipes from japan? which makes me very curious and now I think the pipes are possibly corroding inside and allowing metal into the injectors. One of my injectors blew a huge hole in the nozzle and I don't think water droplets would cause that? I change my filters quite regular and always check for contamination and never found any water or anything in the filters that would indicate dirty fuel. There is nowhere else it can come from? There is also a fine steel mesh filter inline where the fuel pipe enters the main fuel pump and this would positively stop any contaminate getting thru to the pump and rail, and consequently to the injectors so obviously the pipes appear to be the only other source, I would think deteriorating internally. But once the injectors are damaged there is nothing more to do but replace them and make sure no more contaminant can get to them. I'm not totally sure but mazda say the new injectors have to be tuned using their u-beaut computer system after they are fitted? I also have been told to fit a CAV fuel filter with water trap between the tank and the main fuel filter when I finally get my car back from mazda so I can be sure nothing can ever get through from the tank. Seems strange that all the injector problems seem to occur around the 60,000 - 80,000km mark and always only just out of warranty. I'm still waiting for my $bill. Best of luck.

I have 1998 Mazda 626 and I have replaced the transmission 2 times and working on the 3rd one. Was there a re-call on these vehicles that was not published to the consumer? I would like to know if I can...


That is a story which I did not believe when I first heard it. Mazda transmissions can get to 50,000 fairly well but rarely 100,000 so they lowered their drive train mileage warranty to get out of putting so many new transmissions in at their cost. Instead of making better transmissions, just lower the warranty mileage and let the customer foot the bill. I read about it in consumer reports, you may start looking there or just google it. I assume this problem is only for automatics.
