I recently purchased a 1989 Graduate. It ran very rough when I bought it and when I checked the in-tank fuel pump I found that the sending unit was corroded and the pump was not running. Replaced the pump and sending unit but the bracket would not fit so I put hose clamps on the step hose and car ran better but not perfect. I was happy that it would start and run so I could continue trouble shooting, replacing vacuum hoses and on and on.
The last time I tried to start the car, the low fuel light came on and the gauge registered zero; car would not start. Checked the 10amp fuse by the fuel pump relay that the po had installed and it was blown. Pulled the in-tank pump and one of the hose clamps had allowed the hose to slip and the two wires were holding the pump to the fuel tank sending unit. I thought that probably the wires had shorted. Decided to cut the bracket to fit properly and put everything back together minus the hose clamps. Put in a new fuse, turned key and fuse blew. Replaced fuel pump relay with one from Centerline, turned key, big flash and fuse blew. I am using 7.5amp fuses.
Disconnected all wires from in-tank pump, turned key, fuse blew without big flash. Re-connected pump wires, removed fuel pump relay, turned key; fuse did not blow. Put a jumper wire on 30 and 87 on relay, turned key and fuse blew. The fuses blow before I can turn the key to start.
I have been reading all that I can find on the forum to solve the problem but I am getting ready to take it to a mechanic and spend a lot of money to have the car fixed.
