I moved my '94 E420 the other day and it started right up just fine. When I went to move it back later that day, it wouldn't start. The engine cranks but will not catch. Starter fluid does nothing. The battery is fine. Any ideas or places to start diagnosing?

no starts are ether fuel or ignition problems. Since your starter is working then i would check your fuses and do a general visual inspection of your car and see if you can see anything that looks out of place or not working.

Can you hear the fuel pumps at all?
