Occasional sputter and die at Idle
About two weeks ago, I was driving at 65 and the truck coughed. Then 5 miles later did it again and then after another 3 miles it really coughed, decelerated but started running again. Pulled into the local AZ for a scan, but it's a diesel so no go.
Ordered a Bluetooth scanner to link to my phone, and for the next few days It would cough and studder, about 3 times each 15 mile trip to and from work. got the scanner, downloaded "Car Gauge" and "Torgue", Torque found no codes, Car Gauge found some but the light version wouldn't show them. I did a reset, and tried driving it, No more problems for about a week.
Now today, to and from work a couple of coughs, take the kids to soccer practice Dies once coming to a stop, won't start as if no fuel, then on the third round of cranking, it starts and runs fine. Stopped to feed kids and it wouldn't start after numerous attempts. figured fuel pump gave up the ghost. Waited for 5 minutes. Started and ran.
At this point it is parked until diagnosed and repaired.
Here are the code:
I reviewed other posts on these codes. when it runs, it doesn't run rough, not missing half my cylinders. So not the normal connector under the valve cover problem.
My CPS doesn't fail from heat. . . will continue after the cough or die, doesn't have to cool down. (this one I'll replace anyway).
Any direction as to where to start would be greatly appreciated.
I've owned it since new, and other than the fuel bleeder leaking, replacing brakes and fuel filters and doing oil changes, I have been one lucky PSD owner.
