[V8] Dumping Fuel

[cobram at juno.com]

A member of the V8Q brotherhood from Nicaragua, of all places, found my
meager web site, and after a little correspondence, has me stumped.  I
asked him to join our list, but he doesn't speak a word of English.  

1990 V8Q with a 7/89 build, 190K kilometers, used to be some ambassadors
car, dealer maintained till the day he got it.  He says one morning the
car started billowing smoke out the tailpipe along with raw gas blowing
out the tailpipes.  He shuts it down, replaces Fuel Pressure Regulator,
pulls codes (all 4444's-no codes)  starts it up again, and she's still
smoking like crazy, and spitting raw gas out of the exhaust.  

At this point I tell him to check the plugs....#3 cylinder is SOAKED,
rest of the plugs look alright.  Bad injector I tell him, but I also tell
him to check the pulse first.  I am astonished that he didn't hydrolock
the engine.  He tells me the "noid" light is blinking fine when tested
via the self check and when cranking (with the plugs out of the engine),
BUT, he's getting a big gasoline fog cloud out of #3 cylinder that stunk
up half the neighborhood.  Damn, so I have him swap the new injector for
one of the others, he puts the plugs back in......and the thing is still
smoking like a deranged crop duster, still at #3.  He says he went
through 5 liters of gasoline in about 3 minutes running the car.

Anyone have an idea of WTF is going on here???  The injector pulse is
normal, if it was a fuel rail problem it would effect more than one
injector, if it was the computer he'd get a solid pulse at the injector. 
Or is my logic off here somewhere?  I've never come across nor heard of
anything like this on a V8Q before.

Muchas Gracias and BCNU,
