just got the F-U1000 today and could not start the vehicle. Put in a new battery since I needed one anyway, no start or crank. Grounds are clean. Fuses replaced are in good order, no start or no crank. Now I am wondering if it is the TCM. I've put 170,000 miles on the vehicle after the first doing the coolant bypass mod at 10,000 miles. I do all regular maintenance. Any suggestions? Thoughts? I am going to tow to Nissan later tonight, since I have gone through all of the checklists that other posts have gone through. I need this vehicle up and running since my wife is pregnant and will be our baby shuttle. Thanks in advance.
