1993 Mercury Tracer - Ford Escort-Will not start-has good battery

[mrfixit34]

Hi,
I am having a problem with my 1993 mercury tracer not starting,it only has about 90K miles on it.The battery is fully charged and lights do not dim when turning the key on.This car has automatic seat belts also.The radio and inside lights work also.I only hear a small clicking noise for the fan relay switch coming on under the hood and something near the floor on passengers side click when turning the key,looks like an ecm module or something else.Hmm.. Maybe solenoid bad or starter I am thinking. How can I test this without taking the starter out ?BTW,I had a battery charger on boost when starting the car the other day and it started up.Not been able to start it since then.
Could be key switch also or is there a fuse somewhere in line to the starter I could check?
Any ideas on where to start ?

I had checked other sites and found that technician's said they replaced the ignition switch,not the lock. A $20 to $30 part in your steering column
They said this fixed the No Start problem. They said get one from ford since aftermarket parts were not as good. Must have been a ford Tech that posted it.

It could be the relay switch for starter on the firewall or the solenoid could be bad.
I am very doubtful it is the alternator but I'll check that tomorrow with my digital meter also.

I have seen this problem with many tracer and escort cars.. hopefully the ignition switch fixes it.
If we can post link's to parts on websites with photo of the Switch,I would post it here. Can we? yes or no? It would help in identifying the part for other people.

Update..... I got the switch out and took it apart and one of the plastic rods inside was melted that pushes the points down and went to the starter wire, blue and black wire.The points for that were also melted down lower than the other 3 also. I tried cutting off a toothpick same length as the other plastic rods and put it back together with that for testing purposes and still no start. I will have to buy a new switch from a site online for the $23. Local parts stores want me to buy the whole key switch mechanism for $100. Blahh. no way. I tested the power on the 2 black coming in to the switch, and they have power so no fusable links bad.

Make sure the battery cables are squeeky clean and tight at both ends. You can test for voltage at the starter solenoid when the key is turned to start. they are the smaller terminal/s. You might try giving the starter a rap with the wooden handle of a hammer and see if it starts working again. If it does, replace it.
