I've got a problem with my 07 Mazda 3.
Right now it won't start it turns over and has fuel up to the injector rail, also has spark , I don't know if the injectors are firing though .,any help will be greatly appreciated .

 

Ok here's an update . Car set for about 2hours checked spark one more time just to be sure ,still didn't start but had good spark on no.1 plug .put plug back in tried to start still no go. Now for the wierd part tried to start car while pressing the accelerator , car sputtered a little and then started .
What's could cause this problem , oh and no cel.

 

My wifes 06 did the same thing. One day she called me and said it wouldn't start. I check it out and it cranks fine but won't fire. Plugs and wires seem good, throttle body butterfly valve isn't stuck. Cleaned the maf and hooked up obd reader.. no codes...? Tried cranking it once more but this time I gave it a little gas pedal and it sputtered to life. Haven't had an issue since. I have no idea how a car can't start but throws no codes!

 

What timing... the first time my wifes 3 did this was a couple years ago well it just did it again last night. Cranked over with good power but would not fire. Tried it 3 times and it would not start, then started pumping the gas peddle and slowly after about 10 seconds of cranking over it slowly sputtered to life. I was just trying to move it into our driveway and get it off the street so I did that and shut it down.

This morning I went out there and hooked up the scanner to it... no codes! Tried to start it and it started right up! This is ridiculous, someone has to have figured out what the deal is with these by now?? I've searched and there are lots of people who have had the issue but no real resolutions.
