91 plymouth sundance problems

I have a 91 sundance and it has me stumped. Every time i try to start it, it blows the fuel pump fuse. the problem happened gradually so im ruling out a hard wiring problem, and i changed the fuel pump, and later tried unplugging it to see if it still happened. it did. i cant find out if it has a relay for the fuel pump, or where it is at. this info, or any other suggestions because i hear that this is a common problem among these cars, i would appreciate it. Thanx

I got a 93 sundance and the relays are on the driver side about the front wheel. There are 4 of them there on mine. Most of them you can interchange. You can go to autozone.com and you can find out which one it is.
