I just bought a 95 accord about a month ago and just until a week ago it ran great. I was on my way home from work....not driving erratically or excessively fast and I noticed my fuel economy and my power starting to lag so I went home. The next day... when I was getting ready to go to work, I started the car to have it not start up....pop a couple of times and now it doesn't turn over. I jumped the pins for code review and it tells me that I have a trouble code 43..... now I know it deals with fuel supply and possibly delivery but now I'm getting a no crank no start issue also

 

Code 43 is most likely a problem with the oxygen sensor circuit.
