1993 Lumina Shuts itself Off While Driving

Crankshaft sensor.

I don't want to seem like a smart ****, but the blown fuses were telling you that something with the component that it was protecting is going bad. So changing the fuse the first time was a go idea, the second time was not. It told you, that something was failing and you refused to pay attention.

But at least you know which fuse blew, so now all you have to do is find out what it was protecting and replace it or what feeds it.

Code 12 will always be the first code you get which simply meams that your computer and PROM (the memory chip in the computer) are working properly. If you did have a trouble code, how it works is the code 12 (1 and then2 flashes) would happen 3 times. Then after the code 12 any other codes would start. They would also flash 3 times and then move on to the next code and when all the codes were done there would be a longer pause then normal and code 12 would happen again 3 time and the cycle would start again. In other words if no other codes are coming up after the 12 (3 times) you're in good shape and your computer isn't detecting any malfunctions. I hope this helps.

any vacum problems anything like hearter not work right check hose UNDER battery box

I had this happen on another car and it turned out to be a loose connection on the tacho wiring. Fixing the poor connection fixed the problem.

SOUND LIKE A FUEL FILTER PROBLEM...
