Mario R Posted June 20, 2023 Share Posted June 20, 2023 I have a MP7 and it has no power, no active codes and I see that the turbo pressure does not increase, I took the vgt out of the turbo to check the lever but it is ok. There are no air leaks in the fuel system. Quote Link to comment https://www.bigmacktrucks.com/topic/72963-mp7/ Share on other sites More sharing options...

0 Joey Mack Posted June 20, 2023 Share Posted June 20, 2023 well,, I fell like it may be a fuel delivery issue.. I would be curious what the fuel pressure is.. On a gauge, not a computer.... Do you have the tools to check fuel pressure? Quote Link to comment https://www.bigmacktrucks.com/topic/72963-mp7/#findComment-533369 Share on other sites More sharing options...
0 Onyx610 Posted June 22, 2023 Share Posted June 22, 2023 Do you have PTT? If not you’re gonna play a long and expensive guessing game. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/72963-mp7/#findComment-533410 Share on other sites More sharing options...
0 Joey Mack Posted June 22, 2023 Share Posted June 22, 2023 I was wanting to ask him the same thing...

0 Onyx610 Posted June 22, 2023 Share Posted June 22, 2023 Def check the fuel pressure like Joey said. You will more then likely get a CEL sooner then later. Quote Link to comment https://www.bigmacktrucks.com/topic/72963-mp7/#findComment-533412 Share on other sites More sharing options...

PTT and vocomm should come free with every truck purchase. You’re gonna need it…. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/72963-mp7/#findComment-533413 Share on other sites More sharing options...

Me gustaría saber cuál es la presión del combustible... En un indicador, no en una computadora... ¿Tiene las herramientas para verificar la presión del combustible? I was able to repair the truck, I said that it did not show turbo pressure but it did not have a check light. The solution was to change the turbo pressure sensor since it had a lot of dirt that did not allow it to read and that is why it made the error in the turbo and lost power.
