2001 Infiniti QX4 Q&A
2001 Infiniti QX4 Question: ECM replacement
My battery terminals were hooked up backwards. The 120 fuseablelink was blown. I replaced that and the car finally started but would only go 28 MPH tops. I had all other fuses checked and everything's fine. I went to Houston and bought an ECM off of the same year make and model. Same production date and everything. I was told to call an autolocksmith to come to my house and re-program my anti-theft codes. He came out and could'nt get a response from my replaced ECM.We put the old ECM back in just so I could just atleast get the car started again so I could go 28 MPH again and now my car is reset and won't start at all. Neither ECM works now. The anti-theft light is solid red ...not blinking like it was originally. Keys still work and car turns over, just won't start. If you have any suggestions PLEASE call me.

Oh boy, this is a tough one. I would tow this (or drive at 28mph) to a good independent shop or the dealer, have them check all the diagnostic codes, record them, erase them all, and try to start again, see what codes re-appear. Fault trace accordingly. This is a problem that is extremely abnormal, and it will require a very good technician to decipher what has happened and what to do. Bite the bullet and take this to a professional. - Bret Bodas
