Third wind tonight. Replaced the "A/C" light with a red LED. :). Since the panel is already out, now is the time to do it.

Sucks about not being able to drop in that new heater core.
Everything else is making fantastic progress though.
Awesome progress Steve, making the car better in every possible way. These might seem like details to most, but make heaps of difference! Keep up the great work!
Test fire no bueno. Still runs the same. Need to look at the fueling system and rear harness.
Still, I got the HVAC in. New foam tape sealed everything very, very well. The new foam on the latching clamps lock down with a satisfying 'snap'. Dash will go back in soon.

I f-u-c-k-i-n-g LOVE Amazon Prime. Free one day shipping on a Denso fuel pump kit. Pump, all the fittings, hose, duck foot, connectors. Ordered it at 11:30pm last night, it arrived around 10am this morning.
I have ordered something else in the past for the car that I bought in the morning, it arrived that afternoon. Mind blown.
New fuel pump didn't resolve the issue.
It did improve some other things, so I suspect the old one may have been weakening a little. The only items left are the rear harness. To that end, I am going to swap in a known working MAF and CAS. The latest suspicion is that the patched harness may have damaged the ones we tried previously. With the new harness n, there is still something wrong with the timing. Recent rains have slowed progress to a crawl. Still, any progress is good.

It Runnnnnnnnnnnns!
Time to get thrashing, track day at Road Atlanta FRIDAY! Woof.
Woowoooooo
Dash is in. Gauges work. Will bolt it down in the AM. Lots of work left, but I believe I will make the HPDE Friday morning.
These offshore client accounts I am freelancing for leave me with odd hours for work. Glad the contract is almost complete.
Dash is back out.
Popping the main fuel injection fuse (30A). Had to isolate the issue. Essentially, we solved the engine issue, but not the original cause that took the old motor out.
Pouring over the wiring diagrams, previous experience, mitigating circumstances, we narrowed the issue to the circuit controlling relay. It's a bit of a complicated circuit array, nearly impossible to test, but it triggers fuel and timing while related to charging and SRS.
Deductive reasoning is the heavy rains that day the car went south caused the alternator's voltage regulator to spike. No belly tray didn't help. 180k on the original alternator, it just spiked a bit and took down the relay. That messed up the car's ability to fuel and ignite properly.
The new motor runs, but load on the engine while in gear pops the fuel injection fuse and kills the motor. The injectors, ISCV, CAS, fuel pump, even the coils, all trigger from the white/red wire in the harness through this relay.
So, I will order one, after replacing the alternator yesterday. $85 part. Hoping this finally solves it.
Wow, man. This has to be a frustrating witch-hunt for you. Hopefully this will be the last needed replacement for a long while.
Appreciate the sympathy. It has been rough.
On the positive side, the car *should* need very little for a long time. :)
I had a suspicion initially back in August about an electrical issue. If you look at the diagrams on the 90-93, there is a wire (white with red stripe) that is common for the injector harness, CAS, ISCV, alternator, fuel pump, ECU, and ignition. I know on my original harness, I had tapped into it various times for various electronics; Link ECUs, Bipes ACU, J&S knock sensor, etc. I didn't realize the full interconnection of that wire or how it worked in the car. I am not good with electrical issues.
The repairs just snowballed into a lot of people wanting to help and it was a highly complex shotgun approach, in hindsight. I am not complaining, because a lot of people sacrificed time and money to help me and I appreciate every bit of that. It was just the wrong approach and should have been handled differently on my part. This was such an unexpected catastrophic failure, that in all my years owning the car, I never experienced or expected the car to do this. :)
KFJ you have one awesome patience and knowledge to be able to hang with this. You shall be rewarded.
"Why let it go if you really love it in the first place" ;-)
Oh, man. I think my friends are tired of my 'f-it, I'm just going to part it out' rhetoric at this point. :). I credit their patience and my wife's, too, for helping me stay on target.
Relay arrived and I installed it. Car runs. I drove around the neighborhood to test and load the systems. It is in a state of disassembly, so I started putting stuff back together. Dash is in, most of the centerstack, rear carpet.
I blew the meter fuse, so I stopped to diagnose. I think I solved it. It sort of startled me because on the test drive, I looked down and the oil gauge, among others, were not working.
In this whole process, I also replaced the amp. The new one is much smaller in size, but not power. Because I only run the front speakers at the moment, I bridged the amp, so I have about 150w running to each speaker. It is excellent and I am very pleased. The passenger seat also now has full travel.
Hope to button up the car tomorrow or Wednesday.
:)
