1996 should have the new style distributor (sometimes the RV world was slower than regular production with advancements) with a seperate ignition coil.
1st thing to do is determine if it is a fuel problem or an ignition problem. When it does not start, spray some carb cleaner down the throttle body, then crank the engine if it tries to start it is most likely fuel related and probably the fuel pump. If it does not attempt to start it is most likely ignition related. Check the following as these are common in that year.
1. Check for a green deposit inside the dist. if you have this replace the pickup coil and distributor shaft. make sure you replace both. The problem was oil moving up the shaft and damaging those components.
2. Check the computers temperature sensor if it reads incorrectly at normal operating temp. (high) it may not deliver the proper amount of fuel.
3. Check coil wire for a black carbon looking deposit at both connection points (coil and dist) if you have this replace coil and coil wire.
4. Its possible that you have a bad ignition module but that wasnt as common as the items listed above.
Good luck.
