Need to release key to start

Hello i have a weird one here.toyota 7fgu45 ser#61745 (Lpg)
4.3 vortec gm /impco spectrum 3/gdp display.
New crank sensor,distributor,accel sensor,ignition switch, coil,coil wire.no codes, runs great when started. Connected laptop with impco software,no mil, ran adaptive learn cleared.
The only way it starts is if you release key quickly,
If you keep it held all the way it just cranks.
Im hoping someone has ran into this ,any ideas would be great.
Happy holidays.

If ignition is in good condition. Id look at the starter/relay. Or Check your fuses and junction block. There might be a fuse that is getting really hot and melting you can back probe.
