Fuel problems. Please help.
 

Hello everyone,
My father has an '83 olds cutlass ciera 2.5L and its not getting gas. First I pulled out the fuel injector then turned on the ingnition and alot of gas did come flyinging out of the hole. So I assumed it was the injector, bought a new one, installed it and still no gas sprays out when we turn over the engine. My dad hooked up his ohms meter to the fuel injector plug (just the plug) while I was cranking the motor and he said it read 15 volts...? Does anyone have any idea what our problem could be? Any help will be greatly appreciated. Thank you.
