I'm having a no start issue with my 2003 T&C 3.3l I changed the starter, ignition switch,clean battery terminals. After I changed the ignition switch it started ran about 30 seconds and died. Tried again later started and died. Nothing since. Relay is good wire to stater good. I heard to remove the battery box and look for damaged wires all good. We plugged in a code tester and got absolutely nothing didn't even reckonice the car. I l'm thinking its the EMC. But they are spend y so I want to be sure. Is there a way to check them? Please Help.
