My son's girlfriend's 91 Sunbird 2.0 Litre she just bought was hardly making it up hills, then a day later it blew the fuel pump fuse. On checking the fuse it had a 20 Amp. fuse when it should have been a 10 Amp. We figured the pump was pulling too many amps and not pumping enough that it ran rough on the hills. We replaced the fuel pump in the tank and put in a 10 amp fuse. It started fine and ran a couple miles before it blew the fuse again. So now I figure the problem must be in the wiring. Anyone have any ideas? What is the best way to start troubleshooting this problem. Since the only thing on this fuse is the fuel pump would it be easiest to run a new wire from the fuse to the relay and from the relay to the connector going into the tank? Any suggestions really appreciated. THANKS rd
