Screen shots? How are you setting this thing? Also is the particle system set to loop? Maybe it plays once and you don’t see it in time. Is the particle system set to auto activate? Many things could be causing this.
Hi, i have this “Car_BP” and i added a particle component for the smoke effect, it work good, but if i add the car_bp in the scene manualy and press simulate i can see the smoke effect, if i press play and the car is spawned i cannot see the smoke effect, what i’m doing wrong ? Thanks guys.
Ps:Sorry for my english.
Another detail, during the play if i press eject i can see the particle ! If i press posses i cannot see anymore 
I solved, i put “seconds before inactive” to 0
