I have a 2004.5 ram 2500 ctd. I pulled up to red light yesterday and the thig went sluggish then died and will not restart. I got three codes on the dash display:
p2509
p0628
p0882

when I got it home, I checked the voltage on the fuel lift pump and it was 7.3 volts. I read online that the ecm controlled it. Is this true? Are these 3 codes related? Where would be a good place to start troubleshooting?

Thanks Alot
