Yes. It is a difficult job, but not impossible. The hardest part is actually removing the interior door handle. Here are the steps.

1. remove the interior door handle by pressing the door panel in and prying out the C-ring retainer clip
2. remove the lock slide switch bezel with 1 screw, then insert a blade on the bottom left of the slider between the slider and bezel, and release the clip, the slide the bezel toward the rear of the vehicle and pull out
3. carefully unclip the door panel around the lower edge and sides and lift the door panel UP and off
4. remove the interior lock slide switch with 2 screws
5. pull back the plastic vapor shield part way to expose the mechanism
6. there is a cable that runs from the mechanism to the exterior handle, unclip it from the door frame
7. there is a rod that drops down from the door handle to the mechanism, release the rod from the plastic clip
8. locate a large (likely black phillips) screw next to the door handle on the EDGE of the door, remove it
9. locate a 10mm screw on the inside behind the door handle, remove it
10. locate the final 10mm screw behind the handle through an access hole, remove it (careful not to let it fall inside the door)
11. the door handle will push out through the door part way- there is another C-clip securing the lock cylinder that will need to be removed, and the lock cylinder can be pushed into the door cavity
12. pull the door handle through the outside of the door skin- the door handle assembly is still attached inside the door by the latch cable- the cable can be easily removed from the handle assembly to remove it completely
13. you will likely find that the end of the door handle itself is broken off- don’t buy a new handle! Email me and I will show you my free and possibly better solution that will likely last the life of the vehicle dbonnell1972 at yahoo dot com

might be the fuel pump. should sound like an electric motor running, whirring sound. like a very quiet dough mixer.

SOURCE: motor mount, front right, solid or hydraulic?

Hello wrygrl...The OEM (orginal equipment) passenger side motor mount for the 1988 olds ninety-eight was a hydraulic type. After market "solid" type mounts are available for replacement...either type will work. Shop around and get some price quotes, i believe westar makes a solid type mount that sells for around 22 bucks.
Hope this answers your question. Have a safe and happy memorial day weekend.
