My 6.0L diesel won't start

This could be due to multiple issues, but many times when we see this it is due to the low pressure oil pump not creating enough pressure for the high pressure oil pump. When this happens the pickup will not run. Many times the low pressure oil pump will fail slowly and when that happens it can also damage the high pressure pump by not feeding it enough fuel. To confirm that this is the issue we test the low pressure pump and if it has failed then after replacement we will retest and also test the high pressure pump to make sure it was not damaged. If it was damaged then it will have to be replaced too.


Give us a call and let us take care of you. 


Happy Adventures,
