Ok

Quick Back ground on problem and car.

93 R1 Auto DP (Thats it, Mosly Stock)



I am getting a #2 Check Engine light ( That is it no #3) , i have cleared the code a billion times trying to track the problem down.



The Code is there all the time, even if i clear it and then just turn the ignition on (Without Cranking the Motor).



Step

#1 Checked the CAS (NE) Ohm'ed out to 1.13 KOhm's ( Within Spec )(Changed anyways to make sure , Nothing differnt)



#2 Checked the Wiring going from the sensor to the ECU, Ohm'ed out perfect. ( But just incase something was messed up i changed the wires BOTH NE and G signals. THe wire is good sheilded wire. ( Pic Below )

Still have the Code.....



#3 Changed the ECU with 3 differnent Units that where known good, they also show a code.



The thing that is driving my nuts is, I have SPARK on ever plug, in the correct order also. But it is hard to start, if it does at all, Thinking that the fuel injectors and not firing or are dirty. So i sent the injectors to be cleaned. This was after i changed the fuel pump and fuel filter. (What a pain in the Ass) If when i get them back and the motor will not start i will be re-doing the wires on the fuel injectors. On a Side NOTE: How do you do the mod that makes the fuel pump run in high all the time, i may just search for it, but if someone has the answer quick that would be nice.



So i dont no where to go now, i have changed everthing that deals with the CAS'ors. If the ECU was not getting a signal then there should not be a spark, but there is, that's what is Stupping me ......



This is where i am, There has been a few people that have this same problem and they have never found the problem.



I am REALLY thinking about going to Haltech or something like that, this way i no ever sonnection is new.

First off I don't know what #2 warning code is. So if you elaborate a bit about what #2 represents it would help.



2ndly, installing a haltech to remove an engine light is the dumbest thing in the world. SO you want to basically remove a check engine light by using a system that does not have check engine light functions? hrm...

Well the #2 Check engine light is NO NE Signal from the CAS. The manual tells you this.



And i have been on this problem for 4 months and the Rx7Fourm has trow ever idea on the planet at me and i have tryed all of them with out a fix,



So the Haltech was the last option, Replace the entire ECU and all the wiring on the motor.
