    [SOLVED] Car dies while driving and then won't start for a couple hours.

    I never heard any sort of high-pitched whine, but it was real inconvenient when it left me stranded, so I say you did the right thing lmao.

    [SOLVED] Car dies while driving and then won't start for a couple hours.

    It was the in-tank fuel pump, it was overheating, I haven't had any issues since changing that out.

    Are Mazda 6 and MS6 rear brakes the same?

    I'm about to do my first brake job on my MS6, and like with many other pieces of this car, I'm having trouble finding information about the parts I need. Specifically, in my search for brake pads, I have been struggling to find rear brake pads that confirm fitment for the MS6. Most brands seem...

    Cylinder 3 misfire and low/erratic fuel pressure

    Posting one last update to hopefully help someone in the future. I changed out the fuel pressure relief valve and it solved the issue. Fuel pressure is up to ~450 psi at idle, no more cylinder 3 misfire, and car gets to 1600+ psi on just a tap of the throttle.

    Cylinder 3 misfire and low/erratic fuel pressure

    That's good to know. I'm coming from a pre-1975 project car where emissions didn't matter at all, so I am still trying to wrap my head around what I need to worry about and what I don't when it comes to CARB. Thanks for all the advice, I appreciate it.

    Cylinder 3 misfire and low/erratic fuel pressure

    Yeah, I'm not gonna be driving the car unt I get this all sorted out. I don't want to break it more. I just replaced the ITFP and fuel pump relay, which seemed to fix my previous issue. I haven't had any issues with the ITFP since. The car is practically stock, so no upgraded internals...

    Cylinder 3 misfire and low/erratic fuel pressure

    My MS6 has developed a misfire on cylinder three and threw both p0300 and p0303 codes. The spark plugs are all good and gapped within factory spec, I tried checking the coil packs. But after clearing the code to see if the cylinder switched along with the coil pack, the check engine light has...

    [SOLVED] Car dies while driving and then won't start for a couple hours.

    I changed the in-tank fuel pump, filter, and retaining ring (absolutely mutilated the original) and I haven't had any issues with the car shutting off since.

    [SOLVED] Car dies while driving and then won't start for a couple hours.

    It has 3/4 of a tank. I guess my diagnosis wasn't too bad. I'll buy a new fuel pump then.

    [SOLVED] Car dies while driving and then won't start for a couple hours.

    I'm having a curious issue with my MS6. I was driving it late at night when the engine suddenly died, and while it could crank it wouldn't start. The fuel pump wasn't priming. I had to get the car towed home, but when I tried troubleshooting more in the morning it started up without issue. I...
