Can a bad battery cause a ford escort to stall out as if it were out of fuel?
Only if your alternator is not working properly. If you are always charging your battery, check your alternator belt. That was the solution for my escort, a new $10.00 belt.
If the alternator has been checked by mechanics who say it is good can a short or something else cause the battery and air bag light to flash and the battery to die on a 1999 Ford Escort ZX2?
You Need a 35 Series Battery The best answer I can offer is that you need a battery that is a 35 series. They vary from brand to brand such as in Wal-Mart, the brand "EverLife" requires size 35-3S. At CarQuest, it is a 35-84 battery is the size you need. Everything I read says that it works for both a '91 and a '92 Ford Escort (all types).
I have an old 1987 Ford Escort Diesel 4 door hatchback. I need two find the two glow plug relays for it and am looking. Regarding the question about the battery, it is located in the back of the car behind a panel in one of interior quarter panels. There should be a removable panel that you can see, the battery is located behind the panel.
