Does anyone know....
 

My girlfriend has a 2000 celica and she was having trouble starting it today. The starter turns like it's supposed to but the engine didn't catch and start. I don't think i'ts the battery because the starter was turning. Its an automatic and it's kinda cold outside...like high 30's Farenhiet

no gas?

It's the battery. Thing happened to me when I was trying to start my Celica when I owned it. All it needs is a jump-start and it'll be fine.

Obviously not. It cranks over.

If it turns over real fast it may be a broken timing belt

I found this, in case anyone else has a similar problem

Checking your battery

Batteries are probably the biggest single cause for non starting, especially in colder weather. Batteries are less efficient the colder they get so the start of cold weather usually shows up any inefficiencies with the battery. Some of the time the problem seems to point to other things, i.e. the engine still turns over but doesn't fire up. Sometimes this can be due to the engine management system which only turns on the power to the coils if there is enough ampage left in the battery. If the power is too low then the ignition system is not powered up which leaves any power left in the battery to turning over the engine. Without the drain of having to power an ignition the engine turns over quite quickly and you could be forgiven for thinking that the fault lies elsewhere. Check you battery first. It's the most likely cause of non-starting faults and it is free and easy to check.
