Hay i have a 87 na rx7 I've been rebuilding for a few week I finally got it all back together and now my injectors aren't firing the car starts with starter fluid i’ve checked that the egi fuse and relay work i have good fuel pressure and there is a 12v power going to all the injectors any suggestions on wat i should try or check next would be very helpful

 

welcome to board.

here a link to a copy of the FSM (if you don't already have one): Foxed.ca

try finding the ground(s) for the injector circuit. if you've confirmed +12v, then see if it's effectively grounded.

 

I'd say you need to make new grounds

 

I had trouble with this as well, make sure it’s not the injector themselves, take them out and touch them to a 9v battery and they should click faintly. If not give them a nice long bath in diesel fuel and see if that fixes it.
