    Hello this is my first post but I’m on this forum constantly and up till now all my questions have been answered by previous threads but I can’t seem to find anything like my problem. I installed a magnessun supercharger over the past few days did all the steps with the vf tuner to get it licensed and watnot I may have screwed up thinking it was better to wait on the tune till I installed the s/c so everything could calibrate while it’s on the motor but anywho I finished up the installation and went to flash my ecu and the software couldn’t get my vin and kept saying it was unplugged or the key was off. It clearly was not the case. But my truck won’t start and I can’t get ahold of anyone at magnessun (typical from wat I’ve experienced) but I did get in touch with someone at ov tune that is the lead developer it says under his name and he said I have no power to my ecu and upon checking fuses he is correct but the fuses are all good… any help would be greatly appreciated maybe I can get this thing going before magnessun calls tomorrow I’m assuming. Thanks in advance

    I think I need to reset my ecu but every way I’ve read about on here is not doing the trick I think it’s the anti theft system not letting my injectors pump fuel

    I'd need to look at diagrams but I'd bet you missed a ground on the engine when you installed the supercharger, Toyota typically puts their PCM grounds on the uppper parts of the engine. I'd go back and double check you didn't miss anything.

    Well turns out I’m just a big space cadet and totally forgot that at the beginning of the supercharger install it called for me to remove the efi no. 4 fuse lol got it back in and she fired right up thanks for the responses guys I do appreciate it!
