1990 Pontiac Grand Prix SE years later reconfigured with the Supercharger.

New Alternator installed, with a New Battery needed intake manifold gaskets I replaced them. But everything back together now car won't start. Clicking noise I checked the cables and the positive no longer had any visible copper under the cover. Cleaned it spotless then hooked everything back up and still won't start. I suspect arcing at the starter end of the wire. Since the radio is now out as well as the heater motor. Both fuses blew during starting attempts. DO I replace the wires from the starter to the battery or go ahead and replace the starter. I have a new starter as I thought that was part of the initial problem. But car was starting not running long due to intake issues. Fixed those now car won't start just clicks and clicks and clicks.

New battery, like just off the shelf?

Is it fully charged?

Try jump-starting it. What happens?

Battery and Alternator are both Brand New. When she runs she runs really rough then shuts down. Before the Intake Manifold gasket was replaced she ran rough and under idle. Since the replacement she runs rough at idle but still abruptly shuts down. I fear I bent something when she stopped running back in December. Just before she shuts down you can see the BELT literally pause and almost jump off the supercharger. And she sounds flat out terrible.

So . . . This is an NA engine with a SC slapped on top?

. . . or an engine that'* been totally rebuilt to accommodate being supercharged?

What other modifications have been done on this?
