hi i have a 94 integra ls with a b18b in it witch i recently blew up so i went and bought a 2nd gen b16a for it with new ecu i set the timing and it was running good then i shut it off and finished connecting a few thing when doing so a bracket fell down and arked on my alternator now the car wont run it has spark, fuel pressure at the rail but not injector pulse

 

check the fuses.

 

they are good

 

how do you know the injectors aren't firing?

Do you have a noid light?

 

How did you test the fuses?

And like andrew said, what makes you think your injectors aren't firing?
