My car doesn't start with a pfc, but does with stock ecu...I read all the same sensors as my friends except for the "cat" sensor on the sensor check screen..anyone got a idea what that is?

This might be a topic for the ECU forum section, but I believe it is either one of two things.

Either the ECu thinks the cat is too hot, and will not start.... I am not sure if there is a sensor that goes from the air pump to the cat or not...

Did you pull the pins for your power FC? There are 4 wires that have to be cut, or remove the pins from the power FC, if you didn't do this... you're going to have problems.

there is no cat and the wires are cut...

sometimes if you have a sensor error, you can throw a resistor inbetween the pos and negative and get the sensor to read. Never had this problem, so I am not sure on what it is. I'll look around and if I come up with something I'll post.

Catalyzer Thermo Sensor Switch of course!!

I actually have no clue what it's referring to except maybe the overheat exhaust light. I've never even noticed it before.

alright...I am totally stumped on this.

fixed it....CAS wire was messed up...I talked to Steve and he said the stock ecu will still read pulses or something...I didn't quite understand, but it worked! Thanks dhahlen

No problem, glad you got it figured out.

Ah, big difference between CAS & and CAT, what a difference a "S" makes when troubbleshooting someting

pluto

glad that was the problem we talked about, I figured that you probably thought I was full of it when I said it was the wiring that goes to the trigger sensor but I had seen this problem half a dozen times already so I figured that was where your problem was.

maybe i should start charging for phone call questions from now on...... j/k
