Car: 1997 Buick RivieraProblem: Intermittent problem whereby, car will not start. Pull various cables under hood 4 to 7 plus times, car will start.All ground cable connections have been cleaned and tightened. Cables to starter have been cleaned and tightened. Starter relay has been replaced. Ignition key chip has been eliminated at possible problem. This intermittent electical problem seems like a relay or some kind of circuit breaker that releases after a few attempts but nothing is consistent as to what causes it to finally start. Anybody have any ideas or know where I can get a schematic of the starter electrical system for this car? Please Email me at: DarrylHans@aol.comThank you!
