Can someone look at my crazy log?

I have no idea what's going on here. I only have codes 29DC, injector shut off and another one from my post cat o2 sensor being disconnected because I have catless downpipes. I doubt it's my HPFP because I replaced that last year. Can someone decipher this for me?

Why would you disconnect an 02 ?

Your hpfp is not doing its job. At one point it drops as low as 83psi. Quite surprised you dont have a code for this.

As a general rule, your rail pressure should never be below 700psi, even at idle.

The line on the O2 sensor had been damaged, causing it to short out and blow a fuse. I figured since all it does anyway is measure the efficiency of my non-existent catylatic converter, it would be best to just leave it unplugged.

Yeah, I worked through ISTA+'s diagnostics and it tested the hpfp and it confirmed that it was out. I thought I could get away with buying an Amazon HPFP but now I know. FCP Euro here I come.

They also calibrate the primary O2s. I don't think the primarys will maintain their accuracy without the secondaries. So you'll end up with bad fuel ratio. Not sure how far out they will drift.
