How do I get the electrical systems working?

My Trailblazer is completely unresponsive. It won't start (doesn't even turn over), even with a jumpstart. The key is stuck in the ignition and the standard tricks (shaking the wheel/stick) don't help. I can't put the car in neutral, either, so I can't move it at all.

Do you have head lights or any other electrical accessories come on when the jumper cables are connected or is the trailblazer completely dead.

Testimonial: "Completely dead. Literally nothing happens. I should add that I accidentally "jumped" the fuse box recently. Since then, I replaced the "main" fuse and got the car running a couple of times. Then it petered out again. After that, I jumped it once, successfully, and drove it a few miles. Since then it's been completely dead."

    First, check with a test light or DVM that you have battery voltage at the under hood fuse center the 3 large cables that are bolted to it. If you attempted to jump start from the under hood fuse block, disconnect the battery positive at the battery then disconnect at the under hood fuse center. Inspect the connections for any loose or melted plastic conditions. If no voltage is present at the fuse center, check the cables for damage. Let me know if all 3 have voltage on them.

2001 Mercury Sable Intermittent Fuel Pump?

You are right that it could be either component, or something else electrical. The security system will kill the fuel system if the wrong key is used or the system is acting up.
A mechanic would check base fuel pressure with a gauge and also see if the pump is getting power from the relay when it fails to start.

06 trailblazer trouble with anti theft system, I think, starts right up then other times the anti theft light comes on and it won't start. can try it 2-4 hours later and it starts right up????

The first thing to do get it checked for DTC'S - diagnostic trouble codes . Not at auto zone or any other parts store , you want to have full scan of all the modules on the car. Don't know how much you know about automotive electronics , computer controlled systems etc.... Your vehicle has at least 10 modules (computers ) on board , there all talk to each other on a serial data network . C.A.N - controller area network . Or in the case of GM it has it's own . GMLAN -
How to Diagnose Controller Area Network CAN When you turn that ignition switch to start it is an input to the computer ,be it the PCM or BCM ..

'06 trailblazer shuts off while driving;when I try

Look for any lights on the dash when this happens. If you see a light that says security, this is the sign of the problem.

Car won't start

Either an interior light or head lights were left on all night, or there's a dead short in the electrical system, or... the battery completely failed internally such as a weak spot or defect in the plates. At any rate, it all obviously points to the battery. Replace the battery.
