Need some help.

How long was it apart ? I know I have seen injectors stick in the past . Can you hear the injectors clicking(cycling) when the key is on or trying to start it . ?If not , lightly tap the injectors to unstick them . If so , I would be looking at the fuel pump circuit . There are guys on here that know plenty about fuel injection and I am sure they will point you in the right direction . Did you hook up all sending units , etc ? Oil pressure , etc . I cant remember if the fuel pump runs through any of the other sending units as a fail safe or not .
