I recently swapped a 3rz into my 87 4 runner. The engine was completely rebuilt, balance shafts deleted and the head machines for better air flow. The entire engine is brand new. I have an issue though I am hoping for some help on. I starts right up, no CEL and runs great. When I shut it off, it will not re start right away.
What year 3RZ? Usually the coolant temp to ecu has the opposite effect. Wont start/ 5 Minute HARD Start WHEN ITS cold. Will usually fire right up after its been running and the motor has reached operating temperature. Not to say that's not your problem...
