I have a 2007 F-150 and popped the fuse on both power outlets at different times. I replaced them and now they work but now my truck will not crank over, and the check gauge indicator come on. What could have happened???

 

Start by checking Fuse 101 & 102.

Fuse 101 is the power to the starter motor relay, normally open contacts.

Fuse 102 is the power to the key, start position, to the start motor relay coil.

 

I did check those and they are fine. I even swapped them with new ones but it did not help.

 

Did you check with a meter when turning the key, or did you just look at them ?

 

I do not have a meter but if I put new one in wouldn't that work.

 

If it was a fuse problem, yes, I was going on testing from the key to the coil, but that fuse is prior to the key ( just took a closer look ).

Prior to the metering the coil socket for power while turning the key, have you tried starting the truck in neutral with the brakes applied?
- This is just checking another section of the DTR ( Digital Trans Range ) sensor, the truck only starts in park and neutral ( I know stating the obvious ).

You are going to need a meter if that does not do anything.

 

I did get a meter and @ 102 I get power but at 101 no power with the switch at any position.

 

That is the same for both sides of the fuse ?

This is fed from the Yellow w/ Light green wire to the battery. Same supply for Fuse 10, 26, & 24.

Check those fuses for power.

 

I get power for 24, & 26, but not for 10. Now my low tire light is flashing. Thanks for the help.

 

10 or 101 ?

If you are talking about 101, you need to pull the fuse, and check both female spade connectors, and make sure they are in there still.

 

No power to 10 and 101. The spade connectors look good. I can't see behind the panel. Maybe it has a bad wire.

 

If you can see the front, and it looks good, but 2 of them have no power, it is sounding like a problem on the back of the fuse panel.

Time to pull it off the kick panel and check those locations from behind.
