Hi guys I drive an 09 lmm and just got efi installed a week ago today but my truck randomly dies for a split second and comes back no codes are up... What do u do? What can I check any help or insight is greatly appreciated.!!!
Lmm no codes BUT??
- Thread starter Dmaxkry
- Start date
I would put my money on coincidence that it is acting up about the same time you received Efi. My bet is your losing rail pressure/prime somewhere. Data log the start up and failure, save the data, and send it to Rob. I'm sure they will help you diagnose it and get you fixed up!!
Sounds like a loss of rail pressure. Go actively Logg it and watch your rail pressure desired vs actual...
Sorry guys I should be more clear, the truck dies as if you were cycling the elcetrical power with the key and then just for a split second its back on
No I had the shop install the dsp5 switch. The efi, tranny, 40% nozzles, and the twin turbo were all installed in one shot. Not a compleat stall to require start up but just enough to make the truck surge while driving
A log might help some things...maybe they have a lose electrical from moving the battery fir the twins?
I checked all the " add ons " nothing was found don't know what to do now. I did talk to Dustin at ATP about. This he assured me it has nothing to do with the efi tunes he think a loose wire some where but I don't know where to look any more
