New clue on: Long cranking unless 2-1/2 Hr cooldown.

[Louis A. Mulieri]

Hi,
	Thanks to Tony Lum, George Tur, Ben Swann, Ian McArthur, Kneale 
Brownson and Eric Kissell for all the help that's gotten me this far.

I did hook up an indicator light in parallel with the CSV, lo-and-behold, 
start after 3 hr rest...the light flashes briefly on crank and again with 
each revving until warmup. But cranking after 1-1/2 hrs cooldown (12 F 
outside temp)...no flash!!!

So, first guess is the coolant temperature sender is out of calibration 
and claims engine is at running temperature unless it's cooled to below 75 
or so F.

My next problem is finding which sensor is the one that informs the CSV 
section of the computer. I originally thought it was temperature sensor 
trouble and decided according to Bentley for '88 5KCSTQ, p. 25.99a that 
the one on the head-mounted goosneck pointing towards the rear of car was 
the one. It checked > megohms between its 2 terminals and between either 
and ground. I ordered a new one from Parts Bin but didn't put it in 
because it too checked open circuit regardless of being in ice water or 
over gas-stove flame. Besides this confusion, the Bentley figure shows the 
sensor with a plug-type connector with three wires emerging while my 
sensor in that postion has two spade-type connectors with no plug housing 
and only two wires connecting to the spade lugs.

Can someone give me some help in finding the location of the temperature 
sensor that signals for CSV activation?

And, what it's resistance range should be for cold and running 
temperatures?

Thanks for help.
