hey everyone i have a mazda 3 that has been cutting out on me lately does intermitent maybe once a day when i go to start it after id dies it takes about 3-5 seconds of cranking then it fires up, what i have done is installed a new air flow meter, i have put a fuel pressures checker and the pressures does not drop when the car is shaking and 3 seconds later dies, does anyone had a similar problem or has any help for me
thanks. john.

 

Diagnosing problems like this over the internet is just about as effective as throwing parts at the problem in the hope of finding the one that has failed. What you need to do is have the OBD-II codes read so that you can narrow down the source oi\f your car's troubles.

 

i understand mate its hard to diagnose i had a mech who hoped a genuine scanner and had no codes loggod in the current and history of the system, i have swapped fuel still no difference new a/f meter etc.

thanks any help will be great!
