LM 7 that still won't run
 

OK, I had a wiring issue that I think is finished (at least I have spark now) but I can't seem to make fire in any kind of meaningful way. This video is of me cranking and pumping the pedal. I have continuity from the pedal to the TAC and from the TAC to the throttle body. This is a throttle body from the junkyard, but it is doing what the original was doing. I replaced the TPS sensor on the old one, but not this one, because it has the original riveted on still.

Anyway, here's the 41 seconds of futility. Ideas?

That's what data logs are for.
Start the log before you start cranking.

What's the most cost effective way to log data? I have a cheapo obd reader but it doesn't really do data logging.

OK. I have the logged data. I'm not sure what I should be looking for, so I'm just going to share the image and hope you all can help? Values seem consistent, which seems good to me, but something must be off. Still showing a P1125 but no other codes currently.
