Mazda 3 starting troubles
 

hey! I have a Mazda 3 2.0 (think you guys call it the 3i?)

anyways, when sarting in the morning from cold it takes about 6 seconds of turning before it fires up, seems long to me! anyone else experienced this? it is run on 95RON fuel as the handbook states? although it has had a little 97RON when i first got it. but shouldn't make a difference i would have thought?

How cold is it? It's pretty normal for a car to start up kinda rough or take a bit to start when its cold. Mine does the same thing when its real cold.

mine just idles at about~1500 rpm, (instead of the usual ~800) until it gets warmed up, then the idle speed slowly drops down to normal

Fuel pump check valves in the pumps have been a considerable problems on the 3 that creates that exact condition mazda jay. The check valve allows all of the fuel pressure to drop off and then even allows the fuel to drain back out of the lines to the tank so it takes quite a while of cranking to get fuel pressure/ volume built back up.
If the car does this pretty much every morning then try cycling the key from off to run position 3-4 times. Every timeyou cycle the key the fuel pump will run for a second or two. If it then starts right up is a very good indication of pump check valve.
