Engine light stays on after replacing gas cap on my 2003 Dodge tr

First of all, if the engine turns over, you DON'T need a starter or an ignition switch. Don't fall into the 'let's try replacing this' method of car repair! It is costly and never works.

First replace the cap cap, it is part of the pressurized fuel system and may be the answer to all the issues. $20 from Walmart, or $15 from Napa Auto Parts.

Then connect a code reader and find why that Engine Light comes on. Your vehicle has a computer that records everything that is wrong with it. A cheap code reader gives you the basics, a $5,000 scan tool computer tells you everything, historically and in real time as the vehicle is starting of being driven.

The other thing to check is that the battery is good. Interstate will test for you for free in the parking lot and only takes 2 minutes including the printout. I think AutoZone and Napa also does it.

Yes , it's probably the gas cap - the valve in it is stuck shut so the tank gets under vacuum when you start the engine, lowering the fuel flow. Just replace the cap.

If you go to an automotive parts store, most of them have the code reader you can read the codes for, for free. Look online and you will find ouot what fault code you have and that will be the best starting point.
