I would not think so,check the fuel relay,and filter,then take a look at the fuel pump,you can do this by checking the fuel pressure at the fuel rail.

I believe the ignition key has a chip or resistor in it. The ignition can stop reading the key and shut the car down after a few seconds. It's part of the anti- theft system.

There can be many different things that can cause this problem. It could also be the throttle position sensor or throttle plate (butterfly) if it's dirty clean it with carb cleaner.

Tell you the truth ,tuff,all you have replaced,and you have the same issue,im think it may be the ECM,a tps,would not make it,not run,it just would not idle right.I may be wrong,but with all you have done so far,you have spark you have fuel,the ecm go,s stupid within the first few second,s ,then shut,s down,,

This is hard to determine without removing it and haveing checked by a dealer or good mechanic that has the proper diagnostic tool,s to check it,but in this year model they were notorious for going bad,and want show a code for nothing ,,making it hard to diagnose it,it has to be ran threw a program that check,s the ecm,
