1998 Honda Civic Honda Civic died and will not start

My 1998 Honda Civic died while driving down the road. I have had lots of problems with fuel pumps in other cars in the past and thought instantly that would be the problem. After a painstaking lesson of discovering that there was an access plate beneath the rear seat after dropping the fuel tank, I replaced the fuel pump. The car still would not start. The pump is producing pressure because when I removed the line, fuel spurted everywhere. I checked the ignition system by seeing if the spark plug ignited. It did, but the spark was yellow, not blue like I read in another post. Could that be the problem? If not, any other ideas? Thanks.
