1988 4 runner cold start problem
1988 with a 3.0L has no voltage to the cold start injector (wait it has 8 volts with key on and 4 volts while cranking) and will not start cold. When I feed 12 volts to the cold start injector and make it inject fuel the engine will start and run fine. Also the transmission will not shift until it warms up. The thermo time switch, cold start injector, coolant temp sensor, plugs, cap, rotor and wires are all new. Any ideas? I have a wiring diagram and have check all the wires back to the ECU (That has been replaced also) and there is no opens or shorts in the harness.

If you post this in the correct forum you might get some decent responses. Post it in the Classic T4R forum.
