Hello, I have a 1990 Honda Accord EX that six months ago gave me a hard time starting. Turnes over great put wont start. If I try it a few time then it would start and run just fine. This week the problem has come back. I let it sit at work for the day hot weather wont start right away but after a few tries it starts and again runs great. Have changed fuel filter, plugs Any Ideas?? Thanks
