The 1995 Neon was the first Chrysler vehicle to contain the new OBD II emissions diagnostic system. If you don, t have a place to plug in a scan tool, it was cut off, or maybe stolen even. If you need to diagnose the engines ignition, fuel system, and many other systems then you must either find the plug or take it to an auto technician who will install it or locate it. In 1988 Chrysler recommended to not rely on the flashing lamp for detecting trouble codes any longer and I learned that the hard way. There has been a scan plug on every car Chrysler made since 1983 or even earlier. If its not under the dash then look under the hood I can think of 36 codes, just from memory, no one would be allowed to manufacture a car in this country with its emmission laws, that you would have to guess, all the time when you had a spark or fuel management problem. In 1995 no crank reference signal would not turn the Malfunction Indicator Lamp(MIL) on but no cam sensor signal or an intermittant loss of a crank sensor would. Even a non Chrysler scan tool would give you a P1390, P1391, or P0340 code for either a bad crank or cam sensor and either one couls cause a no spark condition. In 1995 only two kinds of cars and trucks would come in to the Dodge dealer I worked at. Either under warranty repair or from a garage or other repair shop.
