i bought my z28 about 2 weeksago i haven't been able to drive it though cuz it's not running, i test drove it once a week prior to buying it, but now i'm getting no fuel to the fuel rail, which is more likely fuel pump failure or faulty relay?

 

All you need is a voltmeter to test either one.

 

you can obviously hear the fuel pump turn on. you can manually prime the fuel pump via the connector on the passenger side to make sure the fuel pump isn't running. check the fuel pump relay as it is an easy fix.
