Not sure but the truck doesn't shut down any more. I think we're good. Thank you everyone for your help!!

Thank you for your response!!! The bulb for the EML was in the wrong socket. The light now works and doesn't have any codes. We removed the line from the turbo curcit that feed the jake and gave it its own line. The jake works well!! Impressive! As for the stalling we are not sure if its was one in the same problem. so a test drive today will tell us. We did notice that the shut down light came on at or about 1800 to 2000 rpms and shut back off at 1500 rpms. The truck wouldn't shut down but i could get the light to stay on. not sure why rpms would influence the light. Thank you for your time.

I really thank you for your time. one last thing did the update also have the turbo line tee'ed into the lines for the jake?

Yes, the update was performed because the jake was not working. When the truck came back from the dealer the jake was performing the same. The update didn't seem to work. The lines are not braided steel. They are a pressure fabric hose with a steel braid inlay. not sure if that makes a difference. The truck was just driven and the driver told me it didn't shut down unloaded. When it was loaded is when it happened. Also it seemed to do it more while he was into the throttle. The first time the truck died it correctd it self. the seconded time he had to turn the key off then back on while rolling in gear. After that he made it back to the shop. Thanks again for the help!!

After a brief ovbservation I noticed that the EML was not coming on and its supposed to on start up. Its also the light for the flash codes so no flash codes. So i have to figure that out too. I have no manuals. It running blind. Thank you for your response!

I have a 1998 mack dump, just got the truck and don't know much about it. The truck will shut down while driving. The first time it happened I filled the coolant and it didn't happen for a while. Now its back to haunt me. the coolant is and was full. The sensor works, I had it plugged in and the shutdown light was off, unplugged the sensor and it came on as expected. What ells should i look for that will shut it down? oil PSI at idle is 60. and for some reason the jake wont work but at low RPMS.
