Why does my Chevy Malibu have no power?

Why does my Chevy Malibu have no power?

When turning the key you’d see a visible spark on the negative terminal, and all power would go (like a dead battery). Adjusting the negative cable would reestablish power. After a couple tries, the car would start. This is why I changed the battery terminal connector to begin with.

Is there a crank on my Chevy Malibu?

All the guages on the dash and all go off, but there’s no crank, no sound, nothing. When I turn back from start to on, all the guages, radio, etc power back on. All the electronics turn on and get good power in the on position lights, radio, windows, etc. It’s when I turn to start, I get nothing.

Is the starter circuit good on a Chevy Malibu?

Checked the starter circuit as described by Ben’s answer. Good power and ground to the correct relays. All fuses are good. Checked wiring to ecm. Ground on X3 73 is good. Confirmed B+ power to terminal 20 red-white on X1.

What does no start no crank no click mean?

If you have a late model GM vehicle and turn the key only to hear nothing, you’ll most likely think you have a dead battery—and you may. But a no start, no crank, no click condition can be far more involved than that. In the old days, power flowed through the ignition switch and down to the starter solenoid. Not anymore.
