I have a 2003 Buick rendezvous & in order for me to start it I have to jump the solenoid, at first the alternator was bad so I replaced it but still wasn't starting, so I replaced the starter, it had been sitting 4 months so I had to get the battery recharged as well. But now that the battery is fully charged i have to jump the solenoid for it to start it up. I let it run about a hour & a half then cut it off & it turned on when I tried right after that but it didn't cut on when I tried about 30 minutes later.
