I need to read closer before responding. <dunce:)
32 psi on the rail, and it could be the pump or the pressure regulator.

Sounds like a fuel pump going south or a plugged fuel filter. A guage
on the fuel rail should show about 40 PSI with the key on and the
engine not running. After startup, it should drop to 30-31 PSI and
maintain that pressure as the engine speed increases. There's a
procedure for doing the full checkout in the service manual, but what
you describe is a classic fuel pump failure.

Fuel pump. My old '84 with a 3.4L replacement would do this went the
electric pump started dying. I had three of them crap out after only a year
on each. Current one's lasted 4 years. But that's probably also due to
putting a much better filter ahead of it between the pump and the tank.
It's entirely possible there's also a lot of crud in your tank that's
clogging the filter. Unlikely, but possible. My tank actually rusted out
to the point of a tiny pinhole developing. When I dropped the tank to
replace it I noticed QUITE a lot of sediment and the bottom of it. Not
saying you should drop the tank but if the pump is inside the tank (dunno
where it is on an '87) and you're already in there it can't hurt to look.

If it is the pump, it is easily accessed from the front of the tank on
our 88 Cherokee. No need to drop the tank. When I see those die, they
usually up and die. They don't give much warning from what I have seen.
