Morning-

Update:  my '95 had been hard hot-starting since Nov.  Cold starts fine,
runs perfect, just cranks 3x prolonged before she comes to live when sitting
for ~ 1-3 hours.  1 out of 5 cold starts it will start immediately, but
"sputter to life" briefly.  Odd.  Also, I had ran it low on fuel in the fall
enough to where I bucked to the pump.  D'oh.

Good news bad news...

Good news:  Fuel pump removal & install is a JOKE, even for me.  If it takes
you an hour you suck.  Should anyone be interested, I'd be happy to do a
write up on the procedure for the archives, lemme know.

Bad news:  remove pump, it's a VDO unit, not the Bosch unit I've got to
replace it with.  OK, that's fine.  But, it appears to be dated in the
casing...  03/01.  UGH!  PO BTDT apparently (price reflected the no records
issue, don't worry)???  OK, so maybe it's still shot.  The list has told me
there's a check-valve in it that is failure prone, and allows the pressure
to bleed off, hence the hard hot-start.  Right?

Go outside just now upon earlier commute to work, doing same thing.  Though
now it does it differently, now it cranks as normal, immediately sputters to
start, then stalls immediately.  Re-start is the 3x crank routine, then
starts / runs fine.

WTF?

Interestingly, I'd done the fuel filter just prior to this issue.  Anyone
ever experienced a mfg. flaw in a filter and gone through this?  I'll likely
swap filters next and see.  If not, anyone have any other thoughts?  More of
a nuisance than anything, but I'm sure the starter strain will add up
eventually.  It really 'feels / sounds/seems' like it's a pressure issue,
hence the sputter to life thang.  No?

Leaky injector?  I don't think it would act like this?
Bad FPR?  I'd assume that would affect the way the car ran / performed in
general?  Or not?
Fuel line leak under car at rubber mount (rust) is causing pressure loss?
Checking this next, though you'd think I'd smell it.

Ah, this is why we love our S cars, right?  They're definitely
"interesting".  Ugh.

TIA, thoughts, suggestions, laughter (expected) are appreciated!
