Re: 89 gta only fires when Jumped
Where are you connecting the negative cable?
Starter should have an always hot cable directly from positive terminal on battery to starter terminal.
Negative cable usually grounds to engine block. Its been a while since I had a stock engine so don't remember the exact layout. My LT1 grounded to the accessory bracket, but I changed the grounding location so it was on the head instead.

No, it's the thing that the wires going to the starter connect to on the starter. It's like a $10-15 part. When it starts to fail, a lower voltage will not be enough to make it work. I can't remember the exact specifics, but if you look it up, it's pretty straight forward. It can be a PITA to replace though. It will be under the exhaust manifold on the passenger side. Make sure to disconnect the battery before messing with the wires to it.

Re: 89 gta only fires when Jumped
Well after Doing a full brake Job on my Jeep I was preparing too put the GTA back in the garage for giggles i tried firing it without having to Jump it she turned over sputterd died okay nbd hit the key a second time lose all power ... check the pos wire nada wiggle the ground wire? Bingo previous owner being a hack grounded it too the header bolt and left it loose.
