94 Lumina apv won't start

Check for voltage at the injectors, if you have voltage then they are recieving voltage, next listen to see if they buzz when your buddy turns the key to the on position or when trying to start. If no buzzing take them out and test them.

Also check the fuel pressure with engine running off of starting fluid, to see if the pressure drops when the starting fluid is out, if so check for a bad fuel pump or no voltage going to the pump.
