Re: car wont stay started
I am not sure what the problem, is with your car. It starts and then dies? Like, in just a couple seconds after starting? or does it stay running until it gets to closed loop?
Before you replace any parts, you have to check your basics. do you have spark, do you have fuel pressure, do you have injector pulse... then, what do you not have when it dies.
#1 security... does the security light come on or flash? If it does the security will shut off your injector pulse right after start up. So, you will have good fuel pressure and good spark but the injector pulse will be turned off.
What was the security code that you had? did you clear the code and then do a relearn?

Re: car wont stay started
It is best to have it check with the car dealership. They know how to detect and fix the problem.

I doubt it is the alternator.
