2001 Malibu - No Start Condition
I'm new to this site and this is my first post.
Looking for some advice to confirm my fuel pump is dead on the 2001 Malibu.
I have a no start condition. So far I've determined the following:
Car cranks but does not start.
Car will run for a few seconds if I spray starter fluid in the throttle body.
No fuel pressure at the fuel rail.
At the fuel pump relay it appears I have a constant power feed at one pin and power feed at a second pin for a few seconds when the key is turned on.
The relay clicks when the key is turned on.
The fuel pump fuse is good.
I do not hear the pump run for the prime when the key is turned on.
How can I confirm I'm getting power to the pump?
Can I apply power to the pump from an external source to see if it will run?
I'd hate to drop the tank and find out it'* not the pump.

Disconnect the connector at the pump harness next to the tank. OHM out the ground wire to a known good ground. Then test for a 2second voltage when key is turned on on the + side of the pump harness.
If you don't have accurate electrical schematics for your car, I wouldn't suggest applying 12v to anything. Things might go boom.
On another note, being your car is 13+ years old, I'm suspecting you have a bad pump anyway.
