Anyone have any thoughts on a '94 Ranger 2.3 5 spd that cranks and cranks but won't start? It has gas at the intake; you get a pretty good shot at the shrader valve. It's getting spark too. Can't even get it to catch on starting fluid. Previously it might stumble and stall two to three times a year when it was foggy or rainy but never really became an issue. Coils or ignition module maybe? I'm guessing spark even though it appears to be getting it I would've thought it should fire on starting fluid.
Thanks!
