Do you have a low battery? Voltage should be 12.5 to 12.7 DCV on a fully charged battery, You would get nothing with 10 volts.


Battery is full


Oh, more awake, you have a V10 engine. So usually it is back at the fuel pump since you worked on it, check for power with a test light or something, more than likely a ground wire. Also check out the fuel pump relay. Lack of power is at one end or the other.


I have a Haynes book but no owners manual. And the Haynes book sucks. Not sure if I have found the fuel pump relay or not. Been googling stuff for days now I have found info staying it could be behind the radio. Any idea on finding accurate fuse diagrams or the relay


Look in the battery junction box...

All depends on the tires.


What you do is go to a lower profile tire.
