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

Car shaking when at lights or stopped


It is most likely to be a timing issue. Too far advanced will cause heavy vibration and lower than normal revs at tickover.

Engine keeps running after key is off


Could be what is called "dieseling" where it sounds like a diesel truck.
Possible causes are a heavy carbon buildup in the cylinders, or the idle speed could be too high.

Ran out of diesel now vehicle won't start


This is not unusual on a diesel. What happens is there is air in the system. If this vehicle has an electric fuel pump loosen line where fuel enters injection pump then turn ignition key to the on position and watch for fuel to appear and then quickly tighten line before turning off key. Then try to start. If does not have electric fuel pump will need a second person. One will loosen line and watch while other cranks vehicle until you get fuel and tighten line before the other person releases ignition switch unless vehicle starts first. If that doesn't do the job do this where line hooks onto each injector. Probably will not have to do this to all injectors but could run rough until all the air gets out of everything. I have farmed with diesel tractor for 25 years and dad I drove the gm vehicles with the 5.7. You normally don't start a diesel without bleeding the air out of the lines although some will self bleed most won't. Hope this does the trick.

Don't know where my return spring goes on my 71 firebird for the clutch.


You should have a heavy return spring under the dash on the pedal and a lighter one on the clutch linkage with one end hooking beside the rod pushing onto the clutch pivot. (some have a small hole for the spring) (The clutch pivot is the part going into the bell housing holding the bearing) and the other end hooking on something that will keep the pivot and bearing away from the clutch when you are not pushing the clutch pedal.
TIP. When sitting stopped for any length of time with the engine running......(and more important with heavy duty clutches)....put the vehicle in neutral and keep your foot OFF the clutch.

Starting ruff


I'm leaning toward a bad sensor, as in throttle body temperature, or coolant temperature sensor. The smell of too much fuel is probably from pushing pedal to start, which shouldn't be necessary on a fuel injected vehicle. What does it do if you leave your foot off the gas pedal during start? As far as fuel filter goes, if it hasn't been done in a while, I'd do it anyway just as preventative maintemance if nothing else.
