bigmike9368 Posted January 2, 2017 Share Posted January 2, 2017 Hello all and Happy New year! My mechanics did an in frame on one of my Macks and now she wont start. Two days of cranking and priming and even some ether( I hate using ether) It will crank fine but no signs of even trying to start. We primed it multiple time to make sure. cracked the injector lines while cranking and we have fuel. Any ideas would be greatly appreciated!

41chevy Posted January 2, 2017 Share Posted January 2, 2017 (edited) Check the sensor on the side of the front cover for the cam. Also the ECU is very sensitive to voltage drop. Anything below 11.5 volts and it gets the lack of the will to work in some cases.

gumbiegumbie Posted January 26, 2017 Share Posted January 26, 2017 the valves probably aren't set right and you are not getting compression. I would think if you gave it either all that other stuff wouldn't matter like fuses and sensors it would at least burn whatever either it sucked in as long as it has compression. Seen a lot of overheads get done incorrectly even more so when the truck has an engine brake. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/48181-2001-ch612-e7-350-wont-start-after-inframe/#findComment-359831 Share on other sites More sharing options...
