1998 Ford Ranger starting

Tell me what do you mean won't start? Does it not turn over at all or does it crank over and just not start?

OK first I would like you check Maxi fuse number 5 it is a 50 amp(in under hood fuse box). If the fuse is good then I need you find the starter relay in the under hood fuse box. Check the yellow wire going to it make sure there is power there. If there is power at the yellow wire to the relay then you need to see if there is power coming from the relay when you turn the key to start possition, check the yellow wire with the light blue stripe or check the wire at the starter solinoid term S wire is same color.
