My idea would be to have it towed to the nearest junkyard, and take the
$50 they offer you for it.  For ghod's sake, it's nearly 20 years old.
Get rid of it.

it is normal that it only runs in neutral and park for automatic cars.
it is because of neutrol swictch.  it is a safety thing.

replacing fuel pump is a waste of money. fule filter is a maintanenece
item.

If you have a cheap junk yard around, try distributor. IT might be very
wise to check all of the spark plugs, and wires. espcieally the
contacts.

One last things, apparently you lag power. itmight be due to jumped
timing belt but i will suggest it as a last resort.

Do you know the comression rates of the cylinders.

I'm sure you lag power due  to firing or firing timing.

good lukc.

it wouldb e much nicer if you provide more infor like millage, motor
size recent maintanence.
