Question about 2003 Lincoln Navigator
Drove last night and all was well. wouldn't start or turn over this morning not even a click like battery was bad. charged battery not problem had battery checked not a problem. it's like power isn't relayed to starter all other electrical seems ok. maybe key switch or one of those computer things that i know nothing about. help please 'cause i don't want to pay out the **** to get diagonosed if don't have to.
This problem is the relay solanoid on the right firewall in the engine compartment. Relay powers everything in the vehicle excluding the stereo and the starter.

What's the odometer reading?
Is there a third party alarm install?
Is there any spark to the plug?
Test the neutral safety switch by pressing on the brake,move gear lever to neutral "N" then start the engine.
Check for excess free play on the linkage.
(moving parts between gear lever to transmission)
Have a helper for view the reverse lights.
Shift the gear lever to reverse and check the reverse lights.
If the light does no come on then the neutral safety switch is bad.
For vehicle with over 140,000 miles,it's wise to inspect the engine and transmission mounts.
A loose transmission mounts will have more free play and wear out the transmission linkage.
Please do these test and let me know the result on reply.
