Angry Hot Start Problems!!

I have a 90 7mgte that will start from cold will restart straight away when hot but if left for a couple of minutes will not startuntil fully cold. There seems to be no signal to the injectors, no power to fuel pump but when bridged will run,all temp sensors work,cps works, even rewired the cps terminals, efi relay works, main circuit relay works.
Any suggestions?? please not the ecu!!

If the fuel pump is the only thing loosing power then the fuel pump resistor pack or relay (mounted to the passenger side fender) may have failed. Try bypassing them, starting with the resistor pack.

Break out the volt meter and start metering any and everything.
Double check all of it.

You'll track it down with minimal effort.

LOL...., did you price hondas and nissans yet??
