You changed fuel pump on 93 plymouth sundance you now have no power to fuel pump what is your problem?

Answer 1

Did you have power to the fuel pump before you changed it?  If so, it's most likely a broken wire in the plug that got damaged when you removed it from the pump.

If you didn't have power before you changed the pump, or if you forgot to check it and just changed the pump without troubleshooting, then the problem is probably the fuel pump relay which is under the hood on the driver side strut tower.  These are a common problem on this year of the model.  

Since all these relays are the same, you can swap the pump relay with the fan relay, just to see if that's the problem.
