[V8] 93 V8 hard to start & no RPM

[Ingo Rautenberg]

Hmm.  Unless the Cat light came on, I can't think that the cats have melted.
 I agree with pulling the codes, though.  She didn't take it to one of them
car washes where you spray it yourself and clean up that engine by chance?
Potential culprits I would think about include the fuel pressure regulator,
bad MAF or water in the potentiometer plug.  But pulling codes would be a
real good idea.
Good luck.
