I just finished my swap. I accidently bought an OBD1 motor, but was able to find OBD0 dizzy, ecu and fuel w/ injectors. Anyhow, I plug everything in except the oxygen sensor and coolant sensor. I try to fire her up and on the second crank it fired RIGHT up. I was amazed. Now, today I go to fire her up and I get nothing, not even a sputter. The only thing that has changed was me wiring in the coolant sensor on the t-stat housing. I was told it doesn't matter which wire is which because it's just a resistance sensor. I'm talking about the sensor thats on the back of the D16A6; on the B16A its on the t-stat housing. I just had used a spare plug from a parts car and extended the wires. The car still doesn't have an oxy sensor.... I actually did manage to get it started but only for a second and it died right away. There is no coolant in the car because my upper hose is on back order. Any ideas? I'm putting a NEW oxy sensor tomorow but still, on the first day it started right up each time, about 5-6 times and stayed running. Possible fault wiring on the coolant sensor? Or perhaps there actually needs to be coolant in the car for it to get a proper reading. Sorry for the long post, I just tried to as specific as possible so people don't have to ask questions and I can just get an answer.
