rotate crank to open intake on cyl 1, take out spark plug, attach compressor hose, blow the plastic backwards out the the way it went in?

I bypassed the fuel pump control unit by putting a wire with two little connectors on it between the blue and red wire and the large black wire. I'm assuming it's the 12 volt wire. it does stay on for the ignition but that's all I wanted this is perfect thank you to all that helped.

Thanks guys for the tips. @ebarb @jono @DaveT @Dee2. Had a friend of mine who's good with older cars look at it. Seems that the distributor was firing in the wrong order. Moved it a few teeth and aligned with tdc and it turned right over!

The "running lights" problem is probably that rocker switch behind the steering wheel. Somehow got turned on.

+1 Both compressors have roughly the same internal volume for moving freon, but the Lexus has a variable displacement compressor where the old school Brat compressor is a fixed displacement compressor so it's pumping full tilt all the time (unless the pressure switch shuts it off). The variable displacement may be mechanical or ECU controlled and is based off system pressures, flow and temp to yield acceptable cooling with minimal load on the engine to keep your MPGs up. Add to that, as you stated, the cabin size difference (Lexus being 2-3x the volume of a Brat) and the fact that R134 does not coll as well as R12 and there you have it. Your Lexus may also be having issues. Low charge, sticky temp door, plugged or stuck orifice/TXV or a cooling fan or condensor air flow issue. Give me old school AC any day.

If I bypass it and it does actually work then I will probably put one of those aftermarket ones that you can wire in and do that but either way I need to figure out which wires are used to bypass it so I can test it in the first place. So I will research as much as possible to figure out which wires are which.

I found one!! Thanks to a member on here that was parting his subie out!!

Junk. KYB or Tokico GD

You buy standard rings, and install them. That's it. No measurement is generally required on standard bore sizes. You can check ring gap if you like. I've never had to gap standard sized rings. If you bore it oversized or are doing a special build with NOS or high boost, etc then you need to gap them for the application. I use NPR rings. GD
