    The TFI Module is world fameous for crapping out so if the car won't start when hot run a quick ignition test check for spark at the Coil and distributor If no spark at the Coil I would try a new Coil and Module good luck.

    Thanks for the suggestions, guys. I haven't gotten around to tinkering with it. I'll try and take a look at it today if my sore throat eases up.

    Can anyone point me in the direction of where the TFI/Coil and Module is? photo or verbal. I'm guessing it's near the cool distributor.

    TFI is on the distributor. It’s shown in this video: https://m.youtube.com/watch?v=dAsEiEzKsHE

    Coil is on the A/C bracket I think or in that ballpark. I moved mine so I can’t recall exactly.

    Here is a video i found that shows the tfi and the tool to remove it. May not be the best quality video but it is short and you can skip through to the important parts pretty easy. For an 80s ford dummy like me it is a good intro to this stuff

    Here is a similar video i found that shows how to test it in the first place with a 12v light. https://www.youtube.com/watch?v=xlKtjBzax10&t=321s
    Like i said i'm still new to this but it seems to help. good luck

    and the pickup is down inside the distributor. Official procedure is to remove the distributor, remove the gear, pull the shaft out, and replace it that way. I've been told, but have not personally verified, that if you remove the "spider" inside the distributor you can pull the pickup out without taking the distributor apart. I don't remember if there is anything to index that spider, but if there is not make sure you use a marker so it goes back in the same way it came out otherwise it'll screw with how the ECM delivers fuel. Its got one skinny finger and thats how it knows where #1 is.

    Thanks guys for all the help. Does anyone think my problem may have something to do with the thermostat? Since it only happens once the engine gets up to operating temperature and it idles fine once it's allowed to cool below 190. Just a thought. Thanks again

    No. The engine should still run even if it's overheating. These things will blow head gaskets before they stop running. The TFI has a known issue that when it fails, it will fail at warm temps but still work when cooled down if it works at all.
