Customer Question
2007 gmc 6.6 lmm...

2007 gmc 6.6 lmm lose power . I put new fuiel injector pump new fuiel pressure sensor, new fuiel pressure distributor . still no power it only goes to 2400 rpms

Mechanic's Assistant: Is the power loss consistent, or does it fluctuate?

Consistent

Mechanic's Assistant: What is the model of your '07 GMC?

2500 hd

Mechanic's Assistant: Are you fixing your 2500 yourself? What have you tried so far?

New fuiel injector pump, new fuiel pressure sensor , pressure regulator

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Iwas in mex. when trouble started , had a computer scan done to it it tochange sensor did not work, nd to change the fuiel regulator did not work had good oil pressure so I drove it home 1600 miles .they did work on computer the told me that it also had a bad injector because of a knock , but I know that lack of fuiel will make it knock .
