Car is a98 a4 Q. 2.8 30v

I just put in a motor but it wont start. I'm not getting any signal to the injectors, and I don't think that the fuel pump is priming.
My thought is that its a relay issue . . So that being said, what is the number for the fuel relay and how do I check to make sure its good??

Thanks in advance. Any and all help is much appreciated.

 

Read the codes and post them.

 

Is it cranking? Check fuel pressure? It's really hard to say what's wrong cuz you put a new motor in. Only thing I can say is recheck ALL of your work and make sure everything is connected to where it's suppose to be. Hoses, wiring, etc....GOOD LUCK
