I got to look at the car this week.
Checked fuel pressure first : 43 psi KOEO, then shut off Ign and checked for 3 min, held steady at 43 psi.
I started the engine and watched fuel pressure, it dropped to about 40 psi but running real rough and was hard to start.
Then I checked the resistance of the new CTS (Coolant Temp Sensor -Delphi #TS10075) and it was reading about 3K ohms at ambient temp.
Then I checked the CTS in the WP and it was essentially off-scale............bingo.
Swapped out the CTS and the engine fired right up without any accelerator help and idled out nice and smooth.
For a quick check I've listed the resistance readings (from the FSM) for that CTS in case anyone runs into a similar problem:
To test the coolant sensor, unplug the wire connector and test the resistance across the two terminals of the SENSOR with an ohm meter.
The sensor screws into the water pump.
Coolant sensor approximate resistance specifications:
177 ohms @ 212 deg. F. or 100 deg. C.
241 ohms @ 194 deg. F. or 90 deg. C.
332 ohms @ 176 deg. F. or 80 deg. C.
467 ohms @ 158 deg. F. or 70 deg. C.
667 ohms @ 140 deg. F. or 60 deg. C.
973 ohms @ 122 deg. F. or 50 deg. C.
1188 ohms @ 113 deg. F. or45 deg. C.
1459 ohms @ 104 deg. F. or 40 deg. C.
1802 ohms @ 95 deg. F. or 35 deg. C.
2238 ohms @ 86 deg. F. or 30 deg. C.
2796 ohms @ 77 deg. F. or 25 deg. C.
3520 ohms @ 68 deg. F. or 20 deg. C.
4450 ohms @ 59 deg. F. or 15 deg. C.
5670 ohms @ 50 deg. F. or 10 deg. C.
7280 ohms @ 41 deg. F. or 5 deg. C.
9420 ohms @ 32 deg. F. or 0 deg. C.
12300 ohms @ 23 deg. F. or -5 deg. C.
16180 ohms @ 14 deg. F. or -10 deg. C.
21450 ohms @ 5 deg. F. or -15 deg. C.
28680 ohms @ -4 deg. F. or -20 deg. C.
52700 ohms @ -22 deg. F. or -30 deg. C.
100700 ohms @ -40 deg. F. or - 40 deg. C.
Thanks again guys !!!
