I did some searching and even though Ford and web sites are swearing the 2007 Navigator has an FPDM, other owners are saying they eventually discovered the fuel pump is controlled by the PCM and their problem was the fuel pump - not the mysterious non-existent FPDM.

One example here. http://www.f150online.com/forums/exp...navigator.html

I did some searching to after my post about rockauto. It does seem to be part of the pump assembly. Go figure

Thanks everyone it ended up being the fuel pump. Idle it works fine but cant keep up under load.

Glad its fixed. One major problem with the Lincolns is there are zero tuner options available. Their PCM operates different than the Ford PCM.

What do you mean by tuner

Ummm... actually, all three SCT devices support them (X4, Livwire, iTSX)

Example: https://www.sctflash.com/Products/pr...cleEngineId=68

The PCM is still a FoMoCo PCM - it's just that some programmers don't support their specific strategy codes. I think the older Edge 15051 was one of them (?). But, AFAIK, Lincolns were always supported by SCT - heck - Troyer ran an old Mark VIII he custom-tuned many years ago.

Oh, well when I looked at a 07 Lincoln when buying my truck, I didnt see a tuner option. Guess I didnt look hard enough. Yet another reason why SCT will be my next choice.

I guessed I didn't look into others but I emailed sct about it and they said it'd work on my truck I just didn't know if you ment something else by tuner
