Hello, I have just swapped my blown(but running 1988 camaro 305 TBI engine so i know it ran fine before) for another 305(from a 87 truck) and everything is hooked up correctly and when i try to start it, it just keeps cranking but does not turn over. I have spark from the distributor, and when i spray ether through the throttle body it starts for a second until the ether is gone. When i look at the injectors while cranking it, nothing comes out. Now i changed the ignition module and the throttle body to the old working ones to see if that changed it, but nope. I was wondering what it could be or if anyone has had the same problem. I'm thinking maybe the pickup? but before blowing $100 I'd come to you guys first. Thank you.

P.S. Old engine is already at the scrap yard so I cant take off from the old engine anymore.

 

I should also mention that the Throttle body is also getting fuel to it. I checked the lines and they are supplying it with plenty of fuel.

 

Fixed it thanks to RBob. It was that I didn't have all the connectors to the distributor.
