Have a 1997 GMC Sierra... has new battery within last 6 mo, NAPA Legend 7578... It has this intermittent starting problem... spins over fine just wont start on occasion... have spark & fuel pump engages & runs as directed. Sometimes I have to turn over 2-3 times & it starts. Today it wouldnt start after long hard start this early in AM... put jumper cables on it & it started. I have noticed when I have this intermittent starting problem all I have to do is hook up jumper cable or battery charger and within a couples minutes it starts up. Do you think I have voltage & not enough amps or vice versa... any thoughts would be helpful. thx.
