They are supposed to be Bosch from jasper this set. It seems blue, but smells horrible of unburned fuel. Once you drive a quarter mile, no smoke, seems to run fine

Thanks, I'll ask the mechanic to check. I'm thinking it might be a bad ground. Also when the new ecm was installed, I'm not sure if the batteries were disconnected, maybe the negative was but he didn't wait 30 minutes and the key was in the ignition. Most likely I wasted 1k on that

I have a 2006 ram 2500 5.9 cummins. Engine ran perfect until I had starter and batteries replaced. After that I was getting a code on banks 6 gun tuner saying fuel rail pressure sensor voltage out of range. Then it started surging from 1k to 3.5k and nearly caused me to wreck. Snap on diagnostic showed 1 injector was weak so I bought that and it cured the surge. The mechanic recommended I have the ecm flashed so I took it directly to the dealer and they flashed it. After leaving the dealership when you hit the go pedal hard I had spark knock and it was smoking bad. Had the mechanic ride with the diagnostic equipment and acceleration I'm showing negative 7 degrees timing. Since then I've replaced the cam position sensor, fuel control actuator, map sensor, full set of injectors, high pressure pump, remanufactured ecm and another set of injectors. I have 13k in repairs and still have the problem. Now another mechanic says it sounds like a bad ground. I know this is long, but I just wanna get it fixed. Currently it runs good warm but fuel economy is down from 19 to 14.2. It's got 168k miles. Any ideas would be great
