Dont guess on parts. Cud b coil or ignition module But 13 sez a vacuum issue. Bad egr or idleair can causeit...and will cause no starting.

I believe it would be blend door actuator problem

No diagrams here! Do an Internet search using Google or Yahoo and find one for yourself. (It's what anyone would do.)

If it is cranking over good, the first thing I would check would be the distributor cap and rotor. The early to mid 90s Dodges had some problems with condensation under the cap. It may not be real visible, but I have had to replace several caps and rotors, both at the same time. Also, using an air hose, blow out the bottom inside of the distributor. And if you can see the vent screen in the bottom, make sure it is clean and open. A lot of times they recommend just removing the screen and trashing it to help avoid this problem again. This is all I know to tell you with the info you have provided. There are a lot of things that will make one not start, fuel psi., crank sensor, etc.

You don't have one. The crank sensor came into vogue with distributorless ignition systems. Before that, the computer got a crankshaft position signal from the pick up coil inside the distributor.

its under your hood, on drivers side, there is a diagram of what they are for on it

The fuel sender is in the fuel tank, whether it is gas or diesel. Sorry for the bad news.

its on the drivers side of the dash board next to the door

Does it quit, then if you sit for a while, re-start for a while again, then quit etc . warmed up, quits, then sits and cools then re-starts?

Make sure distributor cap and rotor are good. Make sure there's no carbon tracking or corrosion inside the cap. Make sure the carbon button isn't worn out. Contained within the distributor is the ignition module. This would give you a no spark condition.

Should be one under the speedometer and one in the engine compartment near the battery.

More than likely the system is low on refrigerant.
