Just wast to see if anyone has experience testing and/or replacing the UVCH in a van.
I'm not sure that is the problem, but it is a 95 and It may be the right time to replace.
Van has been running great lately until Sunday.
I started it up it ran for about 30sec to 1 min then made a strange sound from the drivers side and stalled. No restart.
I'm thinking IDM since it is located on drivers side fender. Not sure if it makes sound when it fails.
The sound continued for a few seconds after it stalled which makes me think it is not purely mechanical.
I tried buzz test no sound and got codes
P1293 and p1294.
If it is IDM I want to make sure it is not something else that caused it to go bad.
Have not had time to pull out IDM.
Will hopefully pull it on Friday.
I have a spare IDM I can use for testing. Comes from a van that ran do I assume it is still good.
Any advice would be appreciated before I tear into it. While I'm in there I'd like to change out any parts that need it since it is an old truck.
Mileage is low, but it probably idled a lot and time takes its toll on wiring plastic and rubber in the engine bay environment.
My experience with the 7.3 is it either runs great or not at all.
I want to take the time to bring it up to a level of reasonable reliability for the summer months.
Thanks
