I have a 2002 ford explorer 4.0 sohc won't crank turn key and it doesn't make a sound. Lights, windows, blower motor, mirrors, radio all work. Wipers won't come on. I have put new battery, new starter, new solenoid. Still nothing
Could be blown fuses or bad starter relay, bad wiring, bad neutral safety /DTR switch, PCM issue, etc. First of all, if this is an early model truck, check fuses 4, 23 and 12 in the fuse box…4 is a 5 amp fuse, 23 is a 30 amp fuse and 12 is a 50 amp fuse. A later model truck would have a 10 amp fuse… Location 29… Instead of the 5 amp for the starter relay coil side circuit.
Fuse 23 supplies power to the ignition switch and then goes through a 5 amp fuse… Location 4 in fuse box (or 10 amp. Location 29 for a late model truck) … To the DTR /neutral safety switch and then to the coil side of the starter relay… Terminal 85… Which is grounded at terminal 86 by the PCM. Fuse 12 supplies power to the contact side of the relay… Terminal 30. Which then powers the starter when the relay is closed.
You should see power at terminals 30 and 85 of the starter relay when key is turned to Start and ground at terminal 86 to PCM. Since the various accessories work, I'd say fuse 23 should be good but fuse 4 or 29 may be bad/blown and preventing power to the starter relay coil side but possibly other issues. Test for power in and out at the DTR or ignition switch if needed.

I don't have a wiring diagram, and there are many different ways manufacturers wire these things up. Try it in Neutral, jiggle the shifter a little.

- I have a 2001 ford ranger with 3.0 and i was off roading when i the truck just shutoff.i stopped it and turned the key no crank at all? I have a 2001 ford ranger with 3.0 and i was off roading when i the truck just shutoff. I stopped it and turned the key no crank at all?
- 2001 Ford Ranger clicks once then won't turn over, and when key is turned off, it begins making a clicking relay noise under the dash? - 1 I've had this happen before, and the last couple times I just undid the battery and put it back in and it started right up. The battery has a charge, the alternator is new, and I tried jumping the battery just in case. So I know it's not that. I'm thinking it could be something in the ignition switch because sometimes I have to lift up on the shifter knob for it to register that it's in park and turn over. Any ideas?
- If I have a 2008 Mercury Mariner and have the key below could I use the standard key and remote? What I mean by standard remote and key is like the ones Ford, Mecury, and Lincoln came out with at first with just a remote and key. Also how would an extra key cost like the one in the picture above? Would it be cheaper to do the the standard key and remote?
- I have a 2000 Ford Windstar that won't start. When I turn the key all I hear is a clunk noise? Battery good, starter good, cables good, fuel system good. No indication before hand that anything was going bad. One morning just went to start and NOTHING.
