06 gtx 155 fuel pump issues

[richardpr]

So my gtx fuel pump primes every few seconds as well as the IAC clicks as well. I checked with the candoo and no fault codes active nor stored. Anyone have this happen before?

I have only read of this once before and he found it to be a corroded E-Box. That is the best I can offer as I do not recall who or when off hand.

I don't recall seeing an e box. Where is it located? Thanks for the idea

The mpem is bad/going bad apparently. Did all the tests and it leads to the mpem

The problem is the ecu on the intake manifold
