1988 honda civic problems with starting, was acting up after we put fuel injection fluidd and was messing up in first and secound gear but when put gas was acting normal but then last time i turned it offf it never started again

Not nearly enough information to go on. What does it do when it doesn’t start? What does “acting up” mean? What does “messing up” mean? Which engine do you have (open the hood, look at the rear of the engine at the part that says PGM-Fi – does it say “Dual Point” above that? That’ll tell me which motor you have).
