So many possibilities, fuel pump may no be
working right. Have to diconnect line to fuel
rail or engine turn key. If fuel is comming out
in a good amount it may be working but still
could stop other times. Fuel pumps suck
because they work then dont all of a sudden
after warm and driving just chuuuum stop. No
crank over wont start. Hour or less later it
starts runs no problem. Alternators, only drain
battery when not working otherwise when
running the alternator is sending power to
everything. So if batery was bad we have to
ask why. If changed and drained again why.
Alterator most likely. So two reasons to check
first, fuel and spark. Main two. Then sensors
malfunctioning elswhere and also, pullies!
Had cars die from ac pully siezed, tension
wheel seized, belt was broken, check belts
and pullies, if they are seized the engine wont
turn! Even with fuel and spark.
