My friend had his 91 regal propped up on some ramps with its nose toward the ground. Started up with no problems. Had been having no problems before then either. Took it off the ramp and now it refuses to start. He thinks it’s the fuel pump. He wants to replace it without dropping his tank, which is currently half full. This is where I come in. He wants me to see if I can find the approximate location of the pump so he can go through the floor board in the backseat. I would appreciate any help provided, as I cannot find a darn thing on the net that doesn’t tell me to drop the G.D. tank. Maybe he should just take it to the crusher.
