I have a 1999 honda civic and the check engine light wont come on, This hole thing started after I added in a new knock sensor and a set of injectors and a clutch, the one injector was bad and was causing fuse 11 in the engine bay fuse box to pop, my car in is particular has a 15amp fuse
anyway i swapped out the injector for an old one and it fired up and I backed it out of the garage and I lost the clutch due to the pressure plate sticking so I pulled the trans back out of it and fixed the clutch and that's when the issue of the crank no start with no fuel pump and I believe no ignition i haven't checked because of the no fuel pump issue and the check engine light doesn't come on when you cycle the key but this time it didn't pop the fuse but my main relay was clicking rapidly so I swapped it out for a spare i had and it clicks normally but same crank no start issue, I have also tested damn neer every sensor on the motor and I read somewhere that a bad crank position sensor could cause this issue but i plugged in another sensor i have off of another motor and still nothing, I have also checked the grounds and added a second ground strap so im starting to think it could be a fues box issue or an ecu but I don't understand how cuz it was running fine the night before and I can still read the codes and the only code it has is for the intake air temp sensor that has been on since ive owned the car, if anyone has any information It would be greatly appreciated because im at the point where im ready to send it to a dealer to see if they can figure it out but I already know it's going to be pricey an rn I don't have that kind of money thank you in advance.
