allow me to watch the oil pressure and other sensors in real time when trying to start my 05 Excursion? Trying to diagnose and determine if my high pressure oil pump is not getting the pressures up due to a leaking/broken seal on its snap to connect (STC) fitting. Or if maybe the injector pressure regulator (IPR) is faulty and/or the screen is blocked on it.
And just trying to determine if it is any other reason why the thing won't start.
If you don't recommend that scan tool, is there another home scan tool that would do what I need for diagnosis?
If you have a bluetooth OBD like elm237 you can use the Forscan demo app https://forscan.org/download.html it has tons of stuff on there.. Should get you where you need to be and there is a paid version also but i havent used since i am waiting on a OBD/usb cable to run the software off of laptop (might be a better option for you). For some reason my laptop doesnt see my bluetooth OBD so i am just going with a wired connection..
I use a elm327 from Amazon I paid $11 for and Torque Pro, works wonderfully! That pic was from me towing this past weekend, pulling out 10k travel trailer.
