Hi,

When I posted I said to use the port where the FPR’s vacuum hose connects to the throttle body.
You will need the tiny spray tube that comes with aerosols and fits the spray nozzles.

No wires on the distributor, means you have to have a CPS.

The CPS sits down on the transmission housing and directly behind the cylinder head. The space for all of this is in between the head and the firewall of the cabin of the car.
It’s held in by one ten millimeter bolt head.

It’s a pain on the elbows and belly to lay on top of the engine bay. You need to get over the area to see down in there.
I have used a thick blanket and a wooden board to support myself.
For me, You have to get comfortable or a whole lot of indescribable words will be muttered from under the hood (:-)
You are also going to need a bright narrow beam of light down in that area too!

I use a 1/4” drive set with an extension bar and sometimes a universal joint swivel helps me line up with a little bit of angle of the dangle. The whole engine is on a slant.
On that swivel, I slip a small o ring over it and get it to fit around and into the joints. I have several kits of O rings
It stiffens up the swivel a bit. Those sockets are fairly heavy.
Most inexpensive swivels are pinned too loosely to be stable and its a cheap fix for it.
In others words, it’s a matched set of cheapness! (:)

If that CPS is original and I doubt it, change it anyway. Moisture works it’s way down the wires and sheath. Time and heat does the rest. I believe Art Benstein has done necropsies on these.

If nothing else the tip might need to be cleaned of debris.
That bell housing is not always the cleanest mechanical area, especially, if you have a clutch. Even the starter can spin up small specks or filings from the ring gear.
That gear is large enough to provide them and will never really show up by just looking at a few teeth when the starter is out.
There needs to be a small air gap between the flywheel and the CPS.

Have you ever removed the battery and checked out the spark coil relay setup there?
It can be a corrosive environment and it’s out of sight and out of mind.
That simple component is an important middle man in the ignition supply chain.
CPS, ICU, system relay, spark relay, ignition coil, coil wire, distributor cap, rotor button, spark plug wires and plugs.
Nothing is more important than the other one.

We are learning how fragile our world is through supply chains.
