My buddy has a Buick Regal Custom 94 with a starting problem. Would not even turn. On day we went to start and it fired right up multiple times that day. Next day nothing. Got the starter checked and it passed. Took multimeter to it and got power from purple and red wire at starter. Got a little remote starter to jump from s to batt terminal and has click every once in a while but not consistent. Next I tried to jump batt terminal directly to the post that leads to starter from solenoid and nothing. Tried both tests with new battery and while getting a jump. Tried all terminals directly from battery terminal. Pissing me off. Please help.
