This process will repair the no start and battery drain due to failed tipm.. The fuel pump relay is built into the tipm and goes bad and causes these issues. This process gives the vehicle a external fuel pump relay. No more 1000 dollar estimates to replace. This cost me a total of 75 dollars in parts from the dealer and about 2 hours of my time.
Part numbers are listed on images,
Will need a soldering iron, crimpers, wire strippers, wire cutters
This is step by step from the dealer and totally repairs the issue
The images are dark but the steps are bold. Good luck!
