I will gladly take the advice of my fellow farmers. Again, there are no codes associated with these shutdowns. So what am I missing? What else can shut the engine down if the fuel shutoff solenoid stays energized during the shutdown? And the fuel pressure never blips right to the point of shutdown? And the ECM stays energized when the engine shuts down? And since it only happens to a warm engine.what else can it be? My internet research shows that this issue happens a lot, but it's usually a coolant level sensor, or a power supply issue to the ECM. Stuck a camera in my tanks to look for a gum wrapper blocking the fuel pickup (actually happened to someone )Ĭomputer will throw codes when certain sensors are disconnected so I think the ECM is working. Voltage is steady from both unswitched positive leads from battery during shutdownįuel pressure is steady at 135 PSI right to the moment of shutdown Voltage is steady from keyswitch to ECM during shutdown Voltage is steady to the fuel shutoff solenoid during shutdown Not sure if that's right, but engine doesn't die when the jumper is disconnectedĬhecked and reset pins on crankshaft position sensor (this is the only connector that will kill my engine when disconnected, but it will throw a code ) The 2 outside wires of the weatherpack terminal on the coolant level sensor circuit have 5 volts of power. New switched power lead from keyswitch to ECMĬhecked coolant level jumpers for continuity (I don't have a coolant level sensor but I have the jumper plugged in ). New unswitched power leads from battery to ECM Here's what we have done since the stalling issue occurred:ĭisconnect/clean/reconnect all sensor leads But since then it's been sitting in my yard because I don't trust it to cross a highway or railroad crossing. It worked great for a day as it solved the derate issue. Had the Cummins guy come out, did his diagnosis and (you guessed it ) replaced the ECM ($4400 ). Last week we had an issue with the computer derating the HP, but it never stalled. Something is happening with a warm engine I think. Works great for the first run to the elevator every morning (15 mile round trip ), then it will start acting up, it will stammer hard or sometimes just stall completely out. I'm in the middle of my grain harvest and my main truck (97 Pete 379 with N14 Plus ) craps out. ( logon | register )Ĭummins N14 stalling out.
