2002 Dodge Ram 1500 4.7 (235,000 miles) was running fine, but died when I stopped at stop sign. Started back up, but was running really rough. Drove it home, and if I stopped without holding foot on gas, it would go dead. Got home and ran codes, and got P 0202 & P 0302. Replaced all plugs and injector on #2. Ran codes again, and got P 0352. Swapped #2 ignition coil with #4 and ran codes again, got P 0354 & P 0355. Swapped ignition coil back and cleared codes, started it again, and got codes P 0300, and ignition coil codes for all cylinders (P 035_) but one or two, and don't remember which ones weren't in list. Drove to store, came back home and it died in driveway. Turned over once, and then wouldn't turnover again (almost like starter locked up). Trying to figure out if this is a ECM problem or if motor is done. Thanks for all your help in advance.

 

Not up to date with all the codes. I assume they are ignition coil (s) and fuel injectors. Maybe pull the valve covers to see if any rockers have . popped off. OR another maybe. A valve seat has dropped out of the head and seized the engine.

 

Maybe an injector went bad and flooded a cylinder, hydro-locking it

Pull the plugs and crank the engine, see what happens.
