I have an 84 190e and I was driving it around until one day it stalled out and wouldn't turn back on. I assumed it was the fuel pump and replaced that but it still wasn't working. I replaced the spark plugs, it needed it, and the battery cuz it was dead. It seems like the new fuel pump isn't getting any power. Can anybody help please?

 

When you turn the key to ON, not start, do you hear the pump come on? You could also pull out the hose from the pump going to the dist, turn the key on, and see if gas pumps out. Always have a fire ext near by when working with fuel.
Check the dist cap and rotor, ignition coil primary resistance, and OVP.
