Hi guys! Looking for some guidance. I have a 2008 RRS SC that died on the way to work. It would subsequently start, run, stumble, stall multiple times. Jumped the fuel pump relay, same behavior. Replace the pump, after running initially for a few minutes, same behavior. No related fault codes on IID Tool. Is it possible ECM is bad and not throwing a code? Am I missing something?



Thanks!

Maybe try disconnecting the MAF sensor which will make the computer go to a "safe default" mode. See if it runs. It could be a bad CPS but I'd think that'd set a code. Do you have 12v+ when it's running? Did you replace the fuel filter?
