i have a 93 honda civic lx 1.5l. engine turns over and it will not start. i replaced the fuel pump and filter. I checked to make sure fuel is going to the injectors and it is. i sprayed some starter fluid in throttle body and it started and then cut right off. i'm getting fire in the plugs. don't know what else to check. can somebody tell me what may be the problem or what i need to do? thanks for any help that is provided.
