92 Camaro 305 TBI. No fuel at the injectors when trying to start hot. Starts fine when cold or within 15 minutes of shutting off, but will not start when hot after being shut off for 15-60 minutes. I can force it to start by disconnecting the block engine temperature sensor; it will start up immediately and run rough until I reconnect the temp sensor, then smoothes out. Other than the starting problem, it runs great, so it's not the obvious things like fuel pump, etc. I can't find a starting sequence diagram to troubleshoot this. Any help please?

(Replaced, tested, or readjusted, most have nothing to do with this: injectors (Holley TBI), coil, wires, plugs, temp sensor, ign module, filters, timing, etc)

Thanks!
