I have to get the part number for the crankshaft bolt again and order one of those also.

Any suggestions on where to order these from that will arrive quickly?

Might have it available at a local dealership(I’d try to call ahead of time to make sure), might even be cheaper cause you won’t have to pay 15$ for shipping a 7$ part lol.

Ok. Vacuum reading is steady but low.
I was leaning towards you having defective heads from the re builder like a sticking valve guide, not fully seating valve or a bad cam, etc. Anything going on with the valves or valve guides would've came out on the vacuum reading and compression test. And you had a steady reading which is good.

Your thermo readings on the exhaust ports were nice and almost even on all 6 cylinders. Indicating a steady flame on all 6 cylinders.

Your compression test was good, somewhat even. No excessive high or low cylinders.

Great vacuum reading would be in the 18-20 range. Your is a steady low 14-13.
So if you go back to the chart on the vacuum gauge pages, it's has defective ignition components as a probable cause.

That chipped tooth could affect the signals going to the ignition coils cause of that low vacuum reading.

I really feel you are close into solving this.

Crank bolt 11/95-9/98: 90105-16031
9/98-...: 90119-16006

Sprocket: 13521-62031

If it isn't the sprocket where would I go next? I'm 99.9% sure, after thinking about how much I inspected the sprocket , that the teeth are good BUT I am human. I may have torn it down 4 times already but I want to be humble in taking advice from you guys so I'm still planning to tear it down tomorrow if that's the suggestion but have a feeling I'm going to be disappointed. I'm not trying to jump ahead, just asking before I proceed.
Edit: I came across this chart while searching a few things. With my readings this narrows it down to late valve timing. Not sure if that makes any difference in which direction to take.

Not trying to be sarcastic.
I have followed you tearing down the timing set more times than you have like trying to execute troubleshooting advice tips this site have suggested. Probably by now you can tear the timing set down, and put it back together then, have the engine running, with your eyes closed and in a great speedy time some of us wish we could do!

You don't have to follow what members here suggest you should do. Some (like me) post what may have worked for me in the past or, post/share what I would do if they were in my shoes.
You are your own person and able to sense what you should do next in your best interest based on what you have seen and experienced.
Like I said, not trying to put anyone down or, be sarcastic. Just trying to help a fellow member out.
Wishing you the best and really rooting for you to have an operational 4r soon!

You're right about nearly being able to tear down and reassemble with my eyes closed.

My question in my last post was not meant to challenge anyone's suggestion. I respect the time that you and others have spent to give advice and only trying to give information that I am coming across. I'm not trying to get around executing anyone's suggestions either. Time is valuable and the last thing that I want is to waste anyone's. I'm only asking questions to learn. Your knowledge on the situation is greater than mine and I have no doubt in anything suggested. I'm really appreciative for all of you in this community.

I apologize if I gave any other impression.

I'm taking everything off the front of the engine and decided to unwrap any wires that I had rewrapped and taped. This is my camshaft sensor and the end of the black wire that mounts to the body of the sensor. I wouldn't think that it's suppose to be this way.

I can confirm that your sprocket is flawless. There is a slight chance that the paint on the end of the tooth could interfere with the crank position sensor, but I really doubt it is the case.

Normally when all cylinders run within a pretty tight temperature tolerance it is likely that the base electricals for the ignition (plugs, plug wires, coil banks) are all completely fine. It also suggests that none of the injectors are firing completely out of whack.

There is still potential with it immediately dying under load (shifting into drive) that it could be something as simple as your fuel pump or fuel filter. Have you done a fuel flow test and check the fuel pressure as steps in this process?

If fuel checks out, I would go on to checking for intake manifold/vacuum leaks.

If everything there checks out, it is likely an issue with sensors, the wiring harness, or even the ECU.

Oh geez louise that's a grounded sensor!! 100% sure that's your problem. Remember what I was saying it was acting like you had a bad sensor? Well you just found it. Is that rats nest of a wire on the connecter side or the wiring harness side? Can't really tell. Obviously, that entire section needs to be cut out and replaced. Junkyard camshaft sensors work fine. I may even have one in my shed if you want it.

And you are saying there's other wires that are wrapped like this???

It is on the connector side but the connector has only 2 contacts so I don't believe it's suppose to be wired to the connector. I reloomed everything while doing this project is what I meant. There are no other wires wrapped up that are in the same condition as this one.

I think that's just shielding in the wiring harness. My electrical wiring diagram lists the camshaft and crankshaft sensor circuits as shielded, and it doesn't look like it's a frayed wire or that there is a spot in the connector for it. The one end of it looks to be grounded to the connector body as well.

I believe that is correct. A new sensor has 3 wires in the sensor side but only 2 go through the wire sleeve and into the connector.

A 30 min trip to the pick and pull and you'll know for sure if that's the problem or not. Shouldn't cost more than $15.

The last wiring harness I got with a donor motor from a later year 5VZ had 3 prongs on the harness and sensor side. My 96 and 97 harnesses both had 2 prongs on the harness and the sensor side. I don't know exactly when the change happened, but that is what mine are like. It is probably just an additional ground and I doubt that section is messed up with just the loom separating.
