Have Truck Repair Questions? Ask an Expert
Hello, My name is***** have extensive Cummins engine experience, and I will assist you with your question today.
I am going to need some more information so that I can quickly pin point this for you. First of all, after the engine stalls, can you crank it and it fires right up again? Or does it crank for a long time then starts, runs rough for a while, then smooths out? Or it won’t start now that it has stalled?
Hello, I’m just checking in to see if your issue has been resolved, or if you require any further assistance? Please let me know how I can help you. Thank you.
Thank you for getting back to me, now let’s see if I can help you with your engine problem.
Just a reminder, I have no way of testing the engine for you, so I will be relying on your information and testing procedures from here on in. I will do the best I can to provide you with professional and accurate information.
One short moment please, while I look up the diagnostic procedures for your issue. Thanks!
Okay, so because your Cummins 5.9L is a Mechanical 12 Valve, there are only a handful of potential things that could be causing your issue. Would you like me to go through them 1 by 1 or would you rather have a printed list you could check them off yourself as you go through each one? If you need help with specs for each procedure or how to step by step, I am here to help, Just Ask! Please let me know what you would like to do. Thank you!
Okay, sounds good! Do you have an aftermarket anti-theft system installed on your truck?
Okay I will send you a list of diagnostics to start going through. Some of them are simple and some you may have already gone through, in that case just check them off. One moment please.
Please take a look at the following attachment. We need to eliminate any possible fuel system issues before going any further. Let me know if you have any questions. Thank you.
Sounds good, and no problem - take as much time as you need, I am here whenever you can get back to me. As you give me results I will check them off, and see what else we can go after in the meantime.
Hello, just checking in to see if you had any luck testing the fuel system? No rush, just checking in. Thanks!
