1992 Cadillac Devile

Deville 92 old. lots to find bad that old. !
here it is, ID #2 below
you were told wrong, the reg is inside the ALT, actual.
the internet lied again.; 1/2 the time, asking 8year kid same.

the top parts sellers online,shows, no REG outside, so strike 2 on reg outside.

learn to keep that old (how old is it?) battery charged fully until car runs perfectly. or it can take 1/2 to jump start it or worse. dead batteries do not start engines and overload the poor donor cars electrics, doing so.(jumped)

once battery is new, or charged or load tested in a real shop
start the engine, see if GEN/CHARGE lamp goes out.? on dash.
if not alt is bad. wow no fuse then, scary then. lots of car fires.
or use voltmeter idling, at bat terms. 13,to 15vdc good below ALt is dead
140amp alt here.

Hi Thomas, Take the vehicle for a diagnostic scan. I suspect the fuel rail pressure regulator. There may be a grain of sand or other matter which sometimes allows it to discharge the pressure and thereby the fuel returns to the tank instead of remaining under pressure in the fuel rail.
