Okay first of all, new member. Hi. Secondly, I do not own an escort. Okay then...Here's the story. My folks own a 2000 ford escort zx2, and they have had a weird issue regarding it. Below are its symptons: 1. When using an OBD reader, it reads 300 degrees even when the car is 3 days cold. 2.Temperature gauge itself did fluctuate. 3. Fans stay on 24/7. 4. Nearly impossible to crank now. 5. When cranking after you just shut off the car, it will crank but will nearly redline at idle. They have tried replacing the instrument gauge wiring, the fan sensor, and the theromstat. I am not familiar with these cars, but is possible that the ECU table that reads the temperature is corrupted? I am leaning towards an ECU issue,so is it possible to reflash a stock calibration onto the ECU or will a new ECU need to be purchased? If it is not the ECU, then what could be causing this? Thanks in advance. Sorry for being one of those douchebags that logs on for one single question, and I know I will get flamed, atleast on my forum, I would if I did this as my first post, but I have exhasuted google.
