I've just gotten a 99 GTP from a relative and had an issue this morning. I went to start it, got a click, and then nothing but warning lights on the dash. Tried a few times and then jumped in my backup vehicle. Chalked it up to cold Wisconsin weather and a questionable battery. Few hours later tested the cells and they were all ok, charge was good. Same issue, but on the second try it fired right up, no cold weather slow start . Tried a few times it it would take a random number of tries before it would start. Then tried again late in the afternoon I tried a few times and it fires up right away.
Talking to a friend, we don't think it's the starter - I believe it has a fairly new starter, they mentioned the lights should dim if it was stuck and they don't.
I don't believe it's the battery connection, they looked pretty clean and I did hit them with a little sandpaper. I've had a car before that had a bad battery connection and the car would completely die (no gauge lights, radio, etc) which isn't the case.
The suggestion I was given was the neutral safety switch.
I have driven the car earlier in the year with no issues and I don't believe it has a history of doing this, but it has been sitting for a while. Makes me nervous and hard to troubleshoot when it doesn't always happen. Most who have issues don't seem to have random ones like this, works or it doesn't.
I do have the issue with the key getting stuck, need to check the wiring. Don't believe that would affect it?
Does anyone have any suggestions on things to check?
