Cranking No-Start on 7MGTE - Crossed Vacuum Hoses

Enginebeginner✓ OP Confirmed

Problem

Recently acquired 1991 Supra Turbo (7MGTE, automatic) would crank but not start. The car had been sitting and was being recommissioned by a new owner.

Engine cranks but will not startCar had been sitting for extended period before purchase

Root Cause

Two vacuum hoses were crossed (routed to the wrong ports), likely from a previous engine pull for head gasket and oiling work. The incorrect vacuum line routing prevented the engine from starting and running properly.
