Default Datsun 280z with 5.3 LS: Having some electrical problems.

Hey guys, my car has been having a little bit of an electrical problem. The car will not start unless it gets jumped. I went out and bought a new battery, terminals, spark plugs, spark plug wires, and even an alternator.

The volts are constantly moving up and down, and every time I give it a little rev, it sounds like it wants to cut off or eventually does cut off.

I'm pretty new to all of this, if someone could help that would be GREAT. Only reason the car is running, is from a jump. After I shut it off, it will not turn back on by itself.

Man to be honest with you, I really don't know. I bought the car with the 5.3 swap in it. I test drove it and it ran fine, but when I got it back to the trailer it keep die'n and struggled to start back up.

Well I guess your gonna have to start by looking at the ground cable from the battery to the body and or frame and then go from there. It could've come loose....Do you know if the alternator is charging?
