Buick century 97 problem

Asked by Aug 02, 2016 at 02:41 PM about the 1997 Buick Century Custom

Question type: Car Customization

I was driving my 1997 Buick Century up
the highway and the RPM's revved up high
and the engine just stopped running and
shut off! I coasted about a mile to a
parking lot in nuetral. But I just want to
know if anyone knows what happened and
what I need to do to fix it ? Thanks :)

Could any number of things, the high revs could have been it leaning out and then no fuel causing it to shut down, timing could have started overadvancing and then the module burned out, crank sensor erroneous signals, total ECM failure. First thing is too see if you can get any codes out of it, hopefully after that you will have some idea on what to check next, or you can repost them back here and someone will jump in and help you with further diagnosis.
