Truck will not start unless Jumped.
This is a problem that has been driving me
up a wall, and I cannot for the life of me,
Figure it out. '98 GMC Sierra with the 305
5.0 stock motor. The truck will only start if I
have it hooked up to jumper cables, and it
gets a jump. Will run fine, but as soon as i
turn it off, and try to crank it again, without
the cables, its dead. Battery is brand new,
alternator passed tests, and starter is new
as well.
