I just swaped in a 95 gsr motor into a 95 civic coupe, after replacing the head gasket and installing the motor it refuses to start.
I double checked the timeing and wiring and every thing seems correct, but I have noticed that the manifold fills with gas when cranking.
When I set fills with gas I mean it's completely flooded, gas pours out the throttle body.

Anybody know why that could be?

Background on the motor: was turbo'd and then one day started blowing black smoke ( which we all know means gas) injectors are stock.

 

Test the fuel pressure regulator

 

Are the fuel injector ground wires all shorted and therefore stuck open?

 

I'll check all of that later this week, the injectors do look they have been re-wired and there's always a chance that they were wired wrong
