At the alternator with the key in the run position see if you have battery voltage at the red wire on the B+ terminal and battery voltage at the red wire on the L terminal.Let me know what you find.

You said that the wire from the starter to the alternator was bad.I hope you used a fuse able link in that new wire. There was one you can see it in the diagram I posted if you don't put one back in then if the alternator ever fail's in the future you could have a fire.

Yes I used a fusable link cable it was a little thicker than the original but it seems to work just fine now but there's still one thing tho when I shift my car in first, second and third its fine when its in forth it putts a bit wile im on the gas at first I thought fuel filter got a new one ran a fuel line test all my injecters are fine and so are my gas line and relay could it be the feul pump or somthing else for fuel pressure I thaught it was the alternater and battery not working makeing it drive like that but with the new battery and alternatter giving full charge it has to be fuel related bc I also have new spark plugs, wires, cap, and coil so its not a miss in the engine.

Alright so it's cutting out you could check and see what your fuel pressure is when it's cutting out. That would be a good start.
