1995 Oldsmobile Ciera Fuel

I have a 95 ciera with the 3100 V6. First the oil pump went out and that put an end to that motor so I purchased a motor from a 94 delta 88, the same size, 3100 V6. Before the engine swap the car had sit for 2 months without the battery hooked up. After I got the new motor in the car it first was not getting anything from the fuel pump. I put a new pump in and then found out the relay for the fuel pump was bad and I changed it. Now I get fuel to the fuel rail, but nothing from the fuel injectors. I was trying to locate a relay for the fuel injectors but have had no luck? The question is could it be the relays went bad while the car sit for 2 months or is it something else that cause the fuel pump to stop in the first place?
