Re: 2006 FS only runs if there is vacuum leak

After more poking around diagnostically. I added a 5v power supply to the ref side of the fuel rail pressure sensor and have it running perfectly. But I don't know why I have only 1volt on my 5v reference from the ECM? would it be a bad ECM or Could it be it needs reflashed to adjust the voltage to ...

Re: 2006 FS only runs if there is vacuum leak

Changed fuel pressure sensor twice second time with ford part. still showing low fuel pressure warning but has high pressure.
I took it to dealership to be reflashed but they said that wont fix a signal like that but I cant think of what else it could be other then maybe a broken wire??

Re: 2006 FS only runs if there is vacuum leak

DanFromSterling I think you are correct in your diagnosis. Long theory... Even though it is not pinched now. That vacuum line goes to the fuel pressure sensor. It probably was pinched and caused the the fuel pressure sensor to think There is a demand for more fuel pressure and probably over pressuri...

Re: 2006 FS only runs if there is vacuum leak

I took it all back apart. Put fresh plugs in there. Put everything back together made sure nothing was pinched. but alas, it still won't stay running unless I create a vacuum leak. wondering if I need a reflash of the ECM??

Re: 2006 FS only runs if there is vacuum leak

Thanks for the reply. I took the whole intake off. I didn't know you could take just the upper off. Doh :oops: but I don't think I pinched anything in there?? Because it did run fine for the first trip after working on it. I'm kinda thinking it is computer or TPS related. I'm wondering what happens ...

He got in and drove about 5 miles just fine. parked it overnight it cranks but no start unless hold full throttle then super rough. I disconnected the vacuum ...
