I believe I would go and recheck the starter installation make sure you have no ground wires on with the battery wire on the starter If it did not do it before and now that you changed the starter you need to go back and recheck your install.Hope this helps if this information is helpful please give me a fixya Rating and if you need any further help with this problem contact me please. Thanks, Randy

That wire may be coming from a relay so you may need a service manual to find which one it is.
BTW, to save frying all of your screwdrivers, applying 12 volts for a moment to the terminal with the smaller gauge wire will cause the solenoid to operate as it was designed. Shorting across the main solenoid terminals lets ~ 100-200 amps flow through your screwdriver which isn't even a very good conductor.
Even a light clip lead to the coil terminal of the solenoid could handle the lower current that flows there.
For purposes of doing several different engine tasks, I made up a momentary pushbutton switch contraption housed in a plastic film canister, put 6' wires and heavy clips on it so I could 'jiggle' an engine into the next cycle.

SOURCE: H2 Hummer
Today 11-12-08 my 2003 H2 Hummer would not start. Checked battery it ischarged. Cables tight. Tried to start with portable booster pak. No go. Tridto jump start with my wife's Suburban. Still no go.
When I turn the switch I hear a single click and that is it. No engine turning over. While trying to start with key the headlights go out. Out of ideas, Will take to Chevy garage in am. Will post solution.

If you had a short that large before you started working on the batt cables, it would have burned long before it did. Check your work over and see where it's grounding. You can make a temporary link by using a new piece of wire the same as the gauge at both ends of the link and sectioning in a short piece of smaller ga. wire. Hopefully you didn't damage the alternator or other electronics. The original problem sounds like possibly the fuel pump anti drain-back valve is bad (integral with pump) Testing pressure will verify that.
You can disconnect alternator, but the fuse method you mentioned sounds more reasonable.
