Answeralot of Ford probes have intermitant starting problems, if you look on the internet for this you will see many people have tried many different things from cheap to expensive. I have found that when my 97 probe doesn't start all i have to do is wiggle any electrical connectors i see ( i have not pin pointed which one)the car will then start. have read people have had to replace electrical harness, but my ways alot easier, for now

Well I had this same problem with our 89 Probe GL. There are multiple temp sensors in the engine which I was afraid was the problem with ours but I found it was an oxygen sensor which had a broken retaining clip. When I fastened it on with a rubber band it quit running badly and not starting in cold weather. Just yesterday when checking out fuses for another issue (headlights) I found that there is a manual "switch" for a fuse under there. One is labeled "warm weather" and the other "cold weather". Since I never knew this was there and it is now warm out, I haven't had the chance it see how it will improve its operation yet. But I intend to find out when I have the chance. Maybe that will work as well for you.
