1987 R30 won't start

[ThomasB0726]

This truck has a 350 K engine. I have replaced the fuel filter, fuel pump and added two new fuel injectors and the truck won't start. I know I am getting gasoline up to the throttle body.

The engine turned over for 1 second after I had installed the fuel injectors, which I think was due to residual gas that came out of the throttle body when I reinstalled the cover. I think I have installed the fuel injectors correctly but if anyone is familiar about what side the injector's side hole is supposed to be facing please let me kno.

Does anyone have any ideas on what else it could be?

Thanks for reading my post.
