Fuel pump?

Datalog won't matter much; your O2 sensors are fucked most likely.

Enki, I hope that it's that simple.

Is it running smoother with the sensors unplugged?

A little but it's still rough. It did run longer. If you watch the video, that's with the O2's disconnected.

In that case O2 sensors might be fine, might be injectors or spark plugs or wiring in general. I'd pull the TMIC, battery, and ECU to be safe, inspect wiring for cuts / kinks / chew marks and inspect the plugs too; maybe even check the ground locations for corrosion/tightness.

What's the backstory here anyways? It's unclear what's going on from the OP.

Due to my schedule the car has sat for a couple of weeks. I start, it roll all the windows down to vent the heat and while I'm sitting there it quits and wouldn't restart.

Are pack rats a thing in your area? Might have a nest under your intake.

No rats, I pulled the tmic and looked around. Put it all back together and used brake cleaner to test for a vacuum leak, no leaks. I think I may need a exorcism on this thing. I'll check the battery and ecu next.

Pulled the battery, disconnected the ECU to see if there is any corrosion. There isn't any. Blades on the ECU are very clean, they look like new. I poke around looking at the wiring and I can't see anything that would cause a problem. I put the battery back in and start the car. The engine light stays on because the 's are still disconnected. ( I pulled the DTC's and it was P2246 O2 sensor voltage circuit high) I started the car to pull a log and the car starts right up and runs good but with a slight miss. Then the car cuts off and won't restart. I'll post the log and try to post the video tonight. I'm beginning to hate this thing....

Did you fix it? What was the resolution? Thanks!

I haven't had time to work on it. A whole lot of bad things have happened since the last time I posted. I'll get back to it soon.

It ended up being the crank sensor. I will update everything soon in this thread, https://mazdaspeeds.org/index.php?threads/a-a-joe’s-cheap-assed-cx-7-daily-driver-build.7865/

That sensor has caused a lot of issues lately. Did you go OEM?

I became so frustrated with the situation and lost access to the SnapOn computer that I used to get the car running, So I called a local shop that has worked on family vehicles. He had to replace the crank sensor and if I recall, It is OEM. I also replaced the purge valve solenoid as suggested by Raider. It was in in a Duralast box.

That raider guy is kinda cool.
