I replaced the spark plugs, I replace the wires, I replace the three coils and it still will not stay running.

How long since overall tune-up? Any applicable trouble codes? To check codes yourself, at the least you need an obd2 code reader. Did you visually check for spark, use a spark tester. Use a gauge and check proper fuel pressure. Also, check fuel injector pulse.

If start and stall, have to check security system. Is there a security lamp on the dash that is on or flashing?

Hello LAWANDA WILEY,

I am sending you some information to help you with the advise JDL gave you. These are links to a couple of articles form this site that feature written step by step instructions and pictures explaining how to do the scan yourself, also I have included a link to our YouTube channel with a how to video on code scanning. In addition I have included a link to another article from this site explaining the process of checking the fuel pressure yourself. If you decide you would like do this yourself you can purchase a fuel pressure gauge online from sites like Amazon.com. Most scanners are fairly inexpensive to purchase. Once you have the codes please get back to us so that we can further assist you. We are always happy to help.
