Hmm... interesting. The only trouble I ever have starting is if it is
sun-soaked for a couple of hours. And doing the cable switch, AKA
hot-start quick-fix, does the trick.

So I should be checking the check valve on the fuel pump or primary
pressure regulator next. What about the TTS (thermo time switch)? I
suppose I should patch into it and see what it is telling the system
cold, vs. running hot, vs. sun-soaked hot.

How does one check the PPR? Checking the fuel pump check valve would
be last resort and may as well replace it all when I get in there.
Thought, I looked into the PO records, the fuel pump combo kit was
done 7.5 years ago (with the accumulator). I don't see that (assuming
it is 102808) in parts replaced back 12/97, and I know I haven't done
that.
