mazda cx7 2.2 mzr diesel
Hi There.
My cx7 2.2diesel would not start every time when hot.
If it does, cut out straight away or running by the sound of it only on 3 cylinders.
Got it plugged in at mazda dealers and there was no faults.
Car just had a service done, so the filters should be okay.
No lights on dashboard as well.
Please HELP ME! !!

Sounds similar to my problem. Starts great when cold, runs perfectly... but if I switch off to duck into the shops or something, won't start again for about 15 to 20 mins. Just cranks and cranks. Mazda dealer workshop said it's injector seals and replaced them during major service, but the problem remains.
Any suggestions?
