I just did a MPFI conversion and it wouldnt start i checked everthing and it still wont start so i checked to see if it was getting fuel and only one injector was squirting fuel. I know the injectors worked when i pulled it but they have been sitting for a year any suggestions? its in a 90 civic std if that matters thanks im guesing there plugged up, can you clean them? the wiring is correct as well.
