Oxygen Sensor
#7
I've never seen a faulty O2 keep a car from running in 15 years of doing this. As important as they are, they are used for reference after the ECU goes into closed loop. If you cold start, it will be in open loop and not look at the O2 for reference until conditions are met for closed loop. If the O2 fails, the ECU will run in safe mode. I have never seen an O2 short something out to the point of disabling a car but anything is possible. If the O2 is old it should be replaced anyway.

Where is the ECU fuse located?? That could very well be the problem. The cat got red hot and the car would not go over 35mph. I figured the 02 was right there and is probably shot. Someis causing the car not to start but it turns over fine.
