Renusha Posted January 17, 2013 Share Posted January 17, 2013 Hi, we have a 1991 mack dumptruck Ch613, Egine E7 400. Since yesterday it starts and shut down immediately back, as if you turned the switch off. The engine shutdown light and the engine mal function light stays on. We already checked the harnass, changed the fuses, changed the fuel pump and still the problem isn't solved. Also we checked the truck with a pro link and it doesn't give us any fault codes.Does anyone have any suggestions or maybe knows whats wrong?

mackattack3 Posted February 1, 2013 Share Posted February 1, 2013 You said the engine malfunction lights comes on. To get the code you turn cruise off and hold down the other cruise button untill the malfunction light blinks. Count the blinks, that the fault code..
