Pic 1 is of 2 circle connectors to one 4 pin. One connector comes from behind the pressure solenoid?

I am thinking the second connector is the cruise control pump which I deleted so I'm thinking I don't need to worry about it

Maybe I'm not following the pictures, but are you wanting to know where the circle connectors go or the one rectangular one?

So I figured out both last night. the MAP circle connectors fit perfectly into the MT harness so while I was plugging everything in (what feels like years ago) I plugged the T harness for the MT into those and this made a 4pin connector appear that has no home. Unplugged the harness and plugged them into each other. Still no start....Looked at timing and I thought it looked right but we wanted to rule it out since it looked like it was possibly a tooth off, after removing belt we could not get everything to line up for 2 hours so we gave up and went home.

Ok, keep us posted. Hopefully you can get everything back together. I use clamps similar to this to hold the timing belt onto the cam gears so you can get everything timed properly.

Timing is now set. Had a nice diag night but still no go. We are not getting reference voltage from the ECU for the crank sensor. Thinking ECU might need replaced now so looking for one if anybody has one for sale.

Here is the main gist the crank sensor wiring was at fault. I had only one harness connector for the CS so I had to use what wiring was left of it. I bought 100ft of shielded 2 wire cable to bypass the harness wiring and go straight to the ECU. Still no start, cranked only. We checked all wiring and it seemed fine but could got no signal and injectors no pulse. From everything I could find and remembered the CS gets 5v reference from the ECU...but after a month of research I found out it doesn't which is good because we almost condemned the computer. The crank sensor only sends millivolts to the ECU. Once we found this out we went through the CS wiring and at the connector I made earlier I had used liquid electrical tape since it was so brittle. Come to find out liquid electrical tape has small bits of metal in it and when you need to send tiny volts any metal across the wires could cause signal to be disrupted. Once wires were fixed the car started, still has a rough idle and will die after a bit but it runs.

Finally able to take it on the road!! Had to fix an overheating issue, idle issue, brake issue but have been taking it out for about 45 min each day to stretch her legs. Current issue is I am not able to get power past 3500 RPMs, it just cuts out . Feels like fuel cut or boost cut. Ordered gauges and looking for a boost controller.

Is the MAF plugged in securely and it's wiring not frayed?
Is the knock sensor crack free, and it's little wiring intact?
Also, have you adjusted the iacv onto spec?

I'll bet at least one is a legit code

MAF wiring is good
Installing a new knock sensor just cause
I have not nor do I know how to adjust have
I also have been roll g with no Speedo cable and am thinking this is causing issues if the ecu reads the input.

Yeah no speedo cable will 100% put it in a minor limp mode. if you like it now, it's so much smoother once that's working.

The auto one is a different length, but I heard of people successfully using it. Glad you got it snapped in.

Speedo cable installed and new knock sensor. Getting codes 22 and 24 but 23 went away. I am going to try and clear them to see if they stay on. Still getting cut off around 3500 RPMs but feels like its getting beter

Ran the green connector test and got 22, 43, 51. The knock sensor is new so possibly the wiring? Not getting any info on the code 43.

Possibly the knock sensor wiring. I had one tiny strand of shielding touching the signsl wire when I fixed my KS plug. About went crazy sorting that out.

I'll try that first. Just got boost gauge and wideband so I'll be installing those shortly as well

While installing gauges I repaired the shielded knock sensor connector and CEL was not flashing at me on my quick test drive but I will do full test tomorrow.
