well, if the car will start with a jump, then its the battery or the charging system.

take the car to a pro, and not the assmonkeys at auto-zone, and have them check the running voltage and alternator current output.

if the alternator checks out fine, replace the battery.

i totally second ivorys statement about the *** monkeys at autozone. take it to a professional that specializes in electronics. i was just currently having electrical problems with my 240 also. me and my dad tried troubleshooting it for almost a week. finally we said screw it cause we couldnt figure it out. we took it to a pro that specializes in automotive electrics and they fixed it today in a couple of hours. your scenario is different from mine (your electrical problem). just cough it up.
