In continuing to work through my 89 Spider, it starts poorly cold, fine hot. I did some diagnostics yesterday (60ish degrees, car stone cold), and came up with:
* Coolant temp sensor: measures 2.76 ohms (spec is 2-3 ohms)
* Thermo time switch: measures .04 ohms (spec is 0 ohms)
* Cold start injector: did not fire any fuel at all on several tries of turning starter
My questions: With the TTS out of spec this small amount, is that enough to make the CSI not work at all? Is it an absolute? If so, maybe I need a new TTS?
Or do I have a bad CSI? I cleaned the contacts on the TTS and the CSI with no change. Is it possible to test the CSI off the car? Does it have an ohm range? Can you send 12V to it to see if it squirts? Perhaps you'd need fuel pressure behind it to get it to function?
Any help appreciated. Thanks
