Only had the car about a month 92 Civic lx will not start. I have checked the code and get 43.( cleared the code) no codes now The fuel pump is coming on. I checked the pressure and it builds up to 40psi with the key on.( Chiltons that is spec.) I changed the fuel filter and still nothing. I also checked for spark and it has spark. The timing belt was recently replaced and it ran fine after. I did not do the work. Any ideas?
