First, I will track down a noid light. Never heard of one untill this morning.

I had tested my AFM previously, I will recheck again to my abilities.
I'm just checking for resistance values, yes?

I replaced the temp sensor II about three weeks ago.

"The ECU  has to see the that the engine turning - it gets that from the
distributor/ignition system.
throttle position switch"

I'll have to look into this, unsure how to test but I am getting spark to
all cylinders and my hall sensor generator tested ok per Bentley.
Does ECU see ignition is turning or AFM is taking in air???
Where is the signal sent to the ECU from distributer???

I dont believe I have a TPS on my aircooled.
But I did re-track my AFM about the same time I replaced the temp sensor.
( i lightly bent the control arm to an untouched part of the signal track)

" and the ECU triggers the fuel pump relay."
(?? doesnt the AFM trigger this??)
"Does the fuel pump run for a few seconds when you turn the key to 'on' ?"

I have fuel pressure (36psi) but not at key on
At "key ON" ONLY the injectors, terminal #10, & AFM #39 (which eventually
powers the fuel pump) have energy.
Fuel does not pump untill turn over, energized from the second relay, then
AFM#39 takes over ONLY when there is air being drawn in the intake (safety
shutoff, or fuel would pump in an accident, right?)

I fell a bit confused now,
Some clarification please
