94 SSE, right?
Disconnect your coolant level sensor in the radiator. It'* the only electrical connection you'll find on the engine side of the radiator. The light will never bug you again.
For the stalling/no start, the best place to look is the battery cables. Pull both boots off the cable ends. You'll find a significant amount of corrosion that can only be seen if you pull the boots. Clean it the best you can, the put it back together with dielectric grease (you can get this at Autozone right around the corner). If the corrosion is too bad, consider replacing the battery cables. Your symptoms point directly at this. We get a good dozen cars a month with these symptoms and this fix. It'* also good to hit the charge terminal on the back of the alternator, the power feed to the starter, and the grounds under the ICM (each end of each red and black cable) at the same time.
Another location to go after while you have all that stuff in progress is here:
I recall you had a water problem in the car? If so, you need to do this.
The ground bus problem may be affecting your cruise control. If not, it could be a slight vacuum leak. We'll cover that if the corrosion issues don't solve your problem.
