had my car jumped off 2Xs once on the way home from work and once before work. my keyless remote works raido dash ect... When i went to jump it for the final time so i could take it to be tested it would not crank, it would idle for about 5 seconds and die, it did that twice. I replace the fuel pump last year the starter 2yrs ago and the battery last year. My guess is its a bad alternator, but i cant crank it (right now) to be sure. would my geuss for an alternator be about right
