<p>[QUOTE=&quot;Chris Arntz, post: 12146732, member: 331866&quot;]Last April in the Indio Ca area, we were leaving the area and making our way home.&nbsp; We got about 30 miles out and all of a sudden the engine just dies.&nbsp; We pulled over and I notice the upside down Amber light.&nbsp; Through DIAG the code was SNP 679 FMI 4.&nbsp; I talked to a mechanic and he told be to disconnect the battery for 30 mins to clear the computer and see if it starts..&nbsp; Well it stated and so we headed back to Indio.&nbsp; Down highway 10 it died again, and somehow using my exhaust brakes started again.. Well I made it to Dillon rd, and it died again..&nbsp; So tried the same thing with the battery and got it going again.. Finally made it back to our Lot at Outdoor Resort Indio... Anyway I had a mechanic try to pin point it for a couple of times, doing test runs while he ran diags..&nbsp; But never figured it out.&nbsp; He was able to run a Force Parked Regen, and it completed that no problem..&nbsp; Anyway we ran our of time, and so we the left coach at our lot all summer..&nbsp; Now we&#039;re back at Indio waiting on another mechanic to show.. He&#039;s been sick.&nbsp; &nbsp; Anyway I looked up the code SPN 679 FMI 4 - IPR Open or short to GND Fault Overview Fault code sets when Engine Control Module (ECM) detects Injection Pressure Regulation (IPR) valve frequency is less than 100 Hz. Lamp Reaction Malfunction Indicator Lamp (MIL) will illuminate when this fault is detected during one trip. Associated Faults None Fault Facts None Drive Cycle to Determine Fault Status Initial Key ON Possible Causes l IPR circuit Open or shorted to GND l IPR PWR circuit Open l Failed IPR valve</p><p><br /></p><p>So I bought a new IPR value and hoping that does the trick...&nbsp; But has anyone ran into this before ?</p><p><br /></p><p>Thank[/QUOTE]</p><p><br /></p>
