the whole car runs off the alternator any time the engine is running, when it fails the gen lamp goes on fast(means ALT just died) then runs on battery for about 1/2 hour and then EFI goes dead at about 10v or even 9vdc. (way too low)
If the engine stalls first, for other reasons (say spark dies or fueling ends) the cluster gen light comes no last, see why?
that is why I told you to test the battery first, then charge it then drive it or start the engine and use voltmeter across the battery see over 12.5vdc up to 15vdc.
if below that , the alternator is DEAD(even at idle) all this is basics, and just power related, electric power is first, or EFI goes dead, if you ever lose your EFI power source, (bat or alt)
your mech will go like arrow to the problem I'm sure.
