injection problems I have a 82regal with a ls1 and it is an electrical nightmare. anyways i have no voltage at injectors and my fuel pump runs with all the time fuel in rail but no run unless i spray starting fluid continously
Check to see if your getting voltage at the injector connector's Pink wires.. if not trace it back to make sure it is connected correctly for Ign 12+ when the key is in Run and Start.
You can also use a noid light plugged into the injector connector and it should be blinking while cranking.

Your fuel pump is staying on but your injectors wont pulse without voltage. Your pump relay is connected to the wrong lead from the engine computer harness. It should turn on for 2 seconds then back off until you start to crank the engine and it is running. You can NOT run the pump directly from the engine computer. You will burn up the computer in a hurry.
Also, testing the lead with a volt meter wont work, you have to use a test light so there is a small load on the lead.
Double check your wiring harness for proper connection to the ignition and work your way back from there.
