If it only fires when you press on the cap then it sounds like an issue between the rotor and the cap. Are your rotor and cap new and are you sure they are correct. It may be just poor quality replacement parts. I recommend buying the best quality parts you can find. Try cleaning the #5 contact on the underside of the cap. Maybe some plastic is overlapping it.

Also are your points adjusted to spec. Did you check it with a dwell meter. Don't assume with a new distributor right out of the box that the points are set correctly. That distributor fits multiple cars and every model has different gap settings.

If it fires when you push down on the cap then why would you suspect anything other than a distributor issue? If the guys at work think they know what the problem is then ask one of them to fix it for you. I'm giving you my opinion but if you think they know more than I do then I won't bother with this thread anymore.

Hey Geoffrey, you likely caught John at a bad moment, but he has a point. There is no 'wiring' inside the cap that would be affected by pushing on the cap. it can only be a problem between the cap and rotor if it is repaired by pushing on the cap. Regardless of what your well meaning co-workers think. Replace the cap and rotor, a lot of what we get from resellers good and bad are repops from China, and most of us have experienced issues with them.

As far as getting advise here. You can take it to the bank, there are a bunch of contributors, John being one of them that have saved me countless hours of trial and error, they've done all of it dozens of times, and are willing to share the knowledge with you. Understand that if they offer you advise and before taking you seek help from your buddies, most if not all of whom have never owned a T-Bird you can see the frustration that might happen. It's up to you whether or not you avail yourself of the knowledge here but it's sound advise!
