I got a problem with my 91 240sx (coupe).

Car starts and runs for 5 minutes and then stalls out. I checked the fuses and it keeps blowing my 15 amp Fuel Pump fuse.

Any suggestions on why it keeps blowing the fuse?

Thanks

Aleks

Too much current draw from the fuel pump, or corroded wiring harness is pretty common. (+1 Fastback240)

happened to me in my coupe as well. ended up being the sending unit connections on the top. +2 for sending unit. I drilled a hole in the top of the sending unit and ran the wires through that then sealed it up with rtv.
