I have a 2000 4.6 4x4
I did a tune up to see if I can get rid of the codes for being too lean and misfiring #5 and the scanner I borrowed will not register anything or say no code but the check engine light is still on the scanner works on my dads f250 and my moms explorer what should I try first

 

Will the scanner light up at all or does it power up and just won't read the codes?

 

It wont power up at all

 

the fuse that powers the OBD port is probably blown. i dont know off hand the fuse # so youll have to look it up, usually its the same fuse that powers the cig lighter.

 

Thanks I'll try that when I get home from work

 

Yeah I guarantee it. On a lot of Ford vehicles it's the same as the horn as well as the power point.

 

Does anyone know off hand what fuse # it is I don't have a owners Manuel

 

you might have a list of the fuse positions on the inside of your fuse box lid check it out and see !

 

I have #s but can't find out witch one is witch

 

Fuse #3, 20 amp
