C15 MXS ACERT starting problem

ecm power

 

So did you run it out off fuel???
Is this why you filled tanks after it quit

 

Exm power first. If it ran rough before stallin it could be a fuel problem

 

Have you changed fuel filters lately? If you did and if you have one on the frame rail did the oring on the threads get installed correctly? Kind of sounds like you got air in the system. When you pump the primer make sure you crack the plug on the left of it to bleed air ( it should be marked bleed or something) and when you get fuel coming out tighten it and pump the primer till it gets really firm. Just my .02

 

With the key on, let cycle though the regular bulb/gauge check. Once that's done, turn the cruise switch off, then hold set or resume for 3-5 seconds. The ECM should give you a flash code. Even with no active faults, you will get a 55 (no faults), if you get nothing, I'd be looking at ECM power/grounds first. Checking flash codes is just a quick simple way to check that the ECM is powering up.

Edit, if the ECM is giving flash codes, at least you know it's powering up, it's not ruling out an ECM power issue, just making less likely. If it gives you an active fault, go in that direction. If it only gives a 55, I'd be checking for a fuel problem..

 

Sounds to me like the transfer pump went out. I had the same thing happen right after I bought my 06 with a cat C-15.

 

Does the rpm gauge move when you crank it over? If so ecm is working. If not and you get flashes from check engine lamp my be camshaft position sensor.
