My Mazda MPV 1995 van was suddenly stopped while driving. The engine turns over and sounds like its getting ready to start but it does not start. Please suggest what could the possible problem. I replaced the fuel filter and checked the mass air sensor and fuel filter and pressure regulator and pressure dampner all of which were not the problem. Also there was a strong fuel smell inside the van prior to this
