Hi,
If possible, could you let me know the code you are getting?
As far as the fuel pressure control module, FPCM, it should set a code if bad. That's why I'm asking,
I am going to provide the diagnostics for the FPCM for your review. If the code you are getting isn't indicated in the diagnostics, let me know what it is.
The diagnostics are attached below.
Let me know if this helps or if you have other questions.
Take care,
Joe
