I have a 2014 ram 1500 5.7L. it is throwing codes p0203 fuel injector, p0303 miss fire cylinder 3. started as just p0303, swapped coil with cylinder 1 and replaced spark plugs. ran a scan when the check engine light started to flash, when i was getting on the gas. gave me the p0203 code. replaced fuel injector. now my electronic brake systems are randomly saying they need to be serviced and kick off my traction control. last thing it did was shut down right after it started and would not start. hit the remote start, it went through its prestart procedures but didnt start, then started with the key. im now thinking the ECM could be going. do you guys have any thoughts or advice?
