I too have a '98 Buick Regal with a similar past but still having issues:
Originally exhibited the same symptoms as described (starts fine but dies shortly thereafter)
- car towed to mechanic, they replaced fuel pump, fuel filter and crank sensor (reading this thread makes me doubt that the pump was really bad
billed about $850)
- drove about 30 miles and died again with the same symptoms
- car towed back to same mechanic and they replaced resistor ($250)
- drove for about 250 miles and died again with the same symptoms
- car towed to different mechanic and they came to the conclusion that it was the resistor ($125)
- after telling them that it had just been replaced, they shrugged their shoulders and gave me the one they had replaced
- I ohmed out the "bad" resistor and it measured the same as the "good"
- I replaced the "good" resistor with the recently "bad" and car started and ran fine
What is going on?
Is there something in the troubleshooting process of testing for the resistor that is clearing some other malfunction (no check engine light)? I'm afraid to count on the car until I find out what is going on. Any help is appreciated.
