Hot start problem, 87 5kcstq

[Burl Vibert]

Nope, not the relay, I can hear the fuel pump running.  I did have similar
weird problems a couple of years ago when the fuel pump relay developed a
cracked solder joint which fed a separate tab going to such things as the
warm-up regulator, O2 sensor heater, cold start valve, etc.
Of course since that the relay was  one of the first things I checked.

BTW, it did it again tonight and I got it going by piling snow on the warm-up
regulator and the temperature sensors.  Not sure which one fixed it.  It also
didn't seem like a leaky injector as until it started there was not even a
sputter, once it did start it ran smoothly as if normal.

Guess I'll try and figure out which temp sensor does what.
