2007 nissan xterra want crank...battery check ok.....replace the starter which old starter tested was bad...still want crank

check fuses and relays.

Which one

Not getting power to the starter

No power to starter

not sure where the relay center is on your vehicle, but it should be labeled and under the hood. there can also be fuses in the glove box and sides of the dash on some vehicles. consult your owners manual if you have one it should tell where they are.

usually they are somewhere near the passenger side fender.

Ok found blown fuse replaced it cranked but only to blow fuse again....now what

sounds like a short somewhere. check wiring at the battery, to the starter and grounds on the block.
