what matters is facts and tests, age is old. but like all old cars, even service can not keep up with age, ok?
like hoses failing is classic, this old. and not changed.
the FPR is failing , that is 1 fact, why we don't know yet. (what if car had a cloned FPR from china put in and it hates USA 10% alcohol)? IDK , that is why I test it,
its simple and classic failure for cars this old. super common. now. the FPR does not have vent hole so is water proof, outside to inside. (see why testing works not blaming all on mr, hurricane?.)
in shop the bucket tests are many but this is only one test, above. (GPH test is another)
the fact is , that time or money is the only issue. (and down time, too, shop labor time and shipping time if local stores have no parts)
testing time and labor
or buy new one cross fingers return lines not bad. you call for sure.
THE FPR IS DEAD or the return line is bad.
or the vacuum nipple is dead. seen one car that had the vacuum nipples packed in EGR GUNK (EGR +PVC black cloud of crap does that in the Plenum)
pull hose, use un bent paper clip or smokers pipe cleaner to clean the nipples, or test the plenum nipple by pulling the hose off vacuum and feel it suck hard.
if vacuum is good, next is return line blocked in all ways stated above.
if that passes the FPR is dead, a very very very common failure now, and service does not cure this, (i mean tuneups. etc)
(service is, (service points only do) fluids,filters, belts, spark parts,PCV valve,and 02 sensor at 100k miles. and nothing else, (unlike air aircraft)
And EGR valve cleaned at 60k for sure.(just engine is topic.)

I have taken fuel cap off, also ran it with 02 sensor out of manifold to see if that helped in case of clogged cat but nothing changed. probably not the best thing to do but tried to start car with only 1 spark plug wire on at a time for each cylinder, and it ran on that 1 cylinder (all 4 but 1 at time ran) This car was meticulously taken care off and the maintainence done regular. we have had it for a couple of years and had driven it about 4000 miles before the flood.
I will check return lines, and run fuel test again.
