No. When hot, the thermal time switch is open circuit, does not fire the 7th injector. Only time it acts to turn the 7th injector is when engine is cold and then only for about 10-seconds of cranking as it's got its own heater that makes it let go of ground. There's a reason its called a "Thermal Time Switch."
Find the lug on the TTS that goes to the 7th injector, i.e. not the +12v wire. Hard wire that lug and the wire attached to it (the one going to the 7th injector) to ground. When cranking the engine, the 7th injector will fire regardless of engine temp. If this 'fixes' your hot start issue, definitely a fuel related issue, not ignition.
