i have a 97 mitsubishi eclipse spyder gs-t with a 95-96 JDM 4G63 motor. heres my problem. all the timing marks are correct, all compression is good. i just rebuilt the motor (it never ran when i got it). my CAS (cam angle sensor) is located behind the intake cam pully closest to the driver side. if i unplug it and start the car it will run but it will only fire on cylinders 1 and 4. but if i plug it up the car dies and wont start, and backfire like hell, like it wants to run but wont. the CAS is brand new.

neone know a fix for this?
