92 Olds Cutlass Ciera Fuel Pump problems

92 Olds Cutlass Ciera, 3300, 127,000, will not start, crank but not fire, no fuel at rail, pump does not come on when key is turned on. Replaced fuel filter.

Applied 12 volts to fuel pump test connection still no fuel pump. Removed connection at fuel pump had 12 volts for 2 seconds when key was turned on. I have continuity between fuel pump test connector and gray wire at harness at fuel pump.

Removed tank, replaced fuel pump, when harness was plugged in the gas gauge went to full (tank is empty) fuel pump will not come on when key is turned on.

Pump will operate when 12 volts is applied from external source (gray wire is hot, black is ground). Purple and blk/wht wires go to fuel level gauge

No codes were stored, ses light did not come on.

Any suggestions?

  1. Did you check if the old pump is dead?
  2. does Fuel system get power when you crank?
  3. did you check fuse?
  4. didyou short relay or hear it click on when you turn the key on or crank?
