fuel pressure

Hey guys new to the forum. I have a 2008 Speed3 that will not keeping running due to what seems to be an issue with the fuel system. It will start cold and run until it essentially warms up and then dies. It will restart immediately then dies within a few seconds. It is exactly as described in...

Hi all, I am new to this forum. I recently bought a used Mazdaspeed 3, after about 600 miles of driving it around to work and during the week-ends, it stalled after about an hour of driving and I couldn't start it again. I had it towed to a safe parking spot and got back home where I have a...

So I'm new here and honestly kinda new to the mechanic life but I know a little more than someone with no knowledge at all. So I have a 2007 Mazda cx-7 Grand touring 2.3L and I got around amazingly for the last year, did my routine oil and maintenance, started having issues and long story short...

Logged HPFP pressure after turning the car off and pressure only...

I've come here as a last resort. Heartbroken over months of trial and error. Recently had the engine replaced, and had put in an Autotech HPFP. She has an HPS CAI and a HKS BOV... I know, it's horrible for the engine, but it came with it when I bought it, and I spent all my resources in...

My 2007 Mazdaspeed3 has been running very rich. You can drive it but I avoid to right now as it will stall at idle sometimes. My AFRs at Idle will be in the 9-12 range most of the time. Cruising is alright, except when you let off the throttle, fuel continues to enter the engine creating pops...

Hello Everyone, ive done the research that i can to find a solution to my problem but the only two threads that had the same problem as me never updated with a solution. I was running a 3rd gear pull while data logging because of a fuel cut i was getting. As you can see my fuel pressure is now...
