Have you tried to see if the starter gets voltage when you attempt to crank?
I would assume not, since a new starter did not fix the problem.
I know that you have to press the brake pedal to close a relay to get voltage to the starter, AND the shifter has to be in P or N.
 
since no voltage gets to the starter, I would check on those circuits (brake pedal switch/wire/relay, shifter position switch/wire/relay.
 
If those are ok and want to send voltage to the starter motor, I am sure there is a big fat relay that handles the full amps of the starter. If that relays gets voltage (from the ECU/PCM) to close, its either the relay or the wires from the relay to the starter. If it does NOT get voltage to close, its in the circuits before (brake switch, shifter).

on 97 cougar xrl 93K miles. had tune up new plug and wires, then check eng light came back on. mechanic put it on computer and checked and got E vap (vac?) code. He told me it was OK to continue to drive and not do anything about this code unless i want to investigate further as it is related to the emissions, said I can ignore check engine light and specifically said " this will not harm your engine in any way". so i ignore the check eng light and keep driving car. since he did tuneup it runs better. but i am worried about the check eng lite and ignoring it. any takers on this one? also - the other day i pulled into a gas station and when the attendant was unscrewing the gas cap my auto door locks started going up and down and the trunk popped open. never had this before. anyone ever heard of this and what could have caused it? a fuse maybe? engine was still on. thanks in NJ

I would also agree the Evap code (what is the code number, like P0320). But one word of caution: on my previous older car, I had the check engine light on (ABS sensor). Then let kids (own and others) use the car for a month. No one noticed (since the CEL was always on) that the oil pressure had dropped to near zero and check the engine oil. Lost the engine in the process.
 
So check codes regulalry (get OBDII code reader cheap from ebay).
 
Here are the codes:

#84 of 153 2001 6cyl Cougar misfire at low speeds code P0401 by decrotty

Jun 14, 2010 (9:04 am)

Lately this Cougar (150,000miles) has a slight misfire at 2000 rpm at low speeds and twice the CEL came on with code P0401 which seems to be EGR Flow Insufficient.
I replaced the EGR valve but the misfire still exists. The CEL has not come on again yet but probably will eventually. Any suggestions?

I may have solved it myself. I found another message that if the throttle body is taken out there are three control holes right inside that get clogged with carbon. All three holes were really caked up on mine. The car has never liked coasting at 2000rpm and then being accelerated even just slightly and that is still there, but the more noticeable misfire seems gone. I'll have to drive it awhile

#87 of 153 95 Cougar Key wont turn - then wont start by mebethy

Jun 29, 2010 (6:49 am)

Hi there,
My daughter has a 1995 Cougar. For a few days her key was not turning and she had to wiggle it and pray to get it to turn. Today when she did get it to turn it not only DIDNT start the car (good battery and started been tested) its making a grinding type noise. HELP please!!!!!!

The key not turning is one issue. Ours is getting worse too. Wiggling the steering wheel still helps. Ultimately, a new lock may be needed (quite expensive I would assume).
 
The grinding noise is worse: we had this issue, put a new starter in, but didn't help. Over time, it got so bad that we had to 'wiggle' the car back and forth (transmission in 'drive' to move the gears of the flywheel a bit to allow the start teeth to mesh in. That worked for a few month, progressively getting worse (since all the grinding naturally wears the teeth of the flywheel/flex plate out even more).
 
At the end, we had to pull the engine out and replace the flywheel/flex plate.
 
You can start with a new starter (already quite some work to remove parts to get to the starter), hoping its the starter.
 
When we pulled the motor, we decided to install a new motor at that time (much less miles; ours had already 140,000 mls on it).
 
Oh: is it really a 95 Cougar (old style)? My notes refer to the newer style (after 1998) !!!!

Assuming the key has something to do with this, spray some lock lubricant or WD40 or something like 3and1 oil into the lock. Work the key in and out a number of times.
I did eventually have to replace the lock on my 2001 Cougar. Any good locksmith can order that lock. If you go to Ford they only have a set of all locks on all doors for about $300.

#90 of 153 2001 6cyl Cougar misfire at low speeds code P0401 by decrotty

Jul 14, 2010 (1:37 pm)

Back again. Have returning P0401 CEL. Getting some misfire at 2000 rpm with slight acceleration. Also may have some misfire at higher speeds but not sure. Replacing EGR valve did not help. Some posts suggest replace the DPFE but some guys report not finding that and I can't find it either. I have the shop manual which shows it under the egr valve mounted on the engine. Does not seem to be there. There are two devices mounted on the manifold, one nearest the EGR valve but unidentified and then next to that is the Vacuum regulator.
Any suggestions? Thanks.
