Guys we started having a issue after him driving the car for several months. It quit on him at the local convenience store do I went and pulled him home. You can cycle the key several times meaning 7-8 and it will start and run great with no issues. If you just turn on the key and try to start it it will crank forever and no start. I’ve changed the fuel filter and the old one was free flow as can be. The codes are 23 and 83 and them blink twice. Meaning 23 again then 83 again. Then it pauses and throws a 72 and then 72 again. I put on a brand new IRMC also. I’m at a lose here.

^^^^ +1 on checking / replacing the ignition switch. Common issue that causes weird issues on all virtually Fords from the 80s thru the mid 90s. I carry a used but known good ignition switches in the trunks of both my Tbirds. New switches are only around $15 to $20 and pretty easy to replace.

Do you have fuel pressure? Turn key on and hear the pump? Push in the schrader valve on the fuel rail (rear, behind intake) to see if you have fuel pressure. Then check spark while cranking. Start with the basics and worry about the codes later (which may have nothing to do with your problem).
