Hello everyone I have a 2003 gt 4.6 2v
My problem is fuel pressure drops a full throttle (wot and mild load between 2000-3000rpm)
Things I have done
Checked frpm power to unit battery voltage 12.8
Checked fuel pump For voltage ok
When condtion is present fuel presure gauge shows fuel psi drops off to
5psi engine sounds as if someone pulled the life out of it
but it does not stall
I gave the fuel pump a direct 12v with frpm unplugged
same condtion present
The fuel pump has been replaced
any one have any ideas ??????
