99 I30 NATS & ECU issues
Hey all.. Looking to collect some info on NATS and ECU for 99 Infiniti I30.
Car started.. ran for 5 seconds, and then engine slowly shut off. Tried to start the car again. Gave er gas, engine ran for about 3 seconds before shutting off. After that, engine would crank, but not start. Had it towed to mechanic. they said I needed to replace the NATS and ECU. quoting me 2500 for everything.
I decided to take the car back home and start doing some research on my own. I did a self diagnostic of the ECU once I got home and pulled 2 trouble codes from the "Check Engine Soon" light/flashing sequence. 1402 and 1401 (EGR Function (Open) & EGR Temperature Sensor) - Which seems to be correlated to engine coil failures (Which I have has 2 coils replaced in the last 2 years) - but that's a side story for now..
Question #1 - If I am pulling trouble codes from the ECU is there still a chance that my ECU is bad/fried? Seems odd that I would be able to retrieve codes, but the mechanic says my ECU is bad?
Question #2 - If my ECU is OK.. what other things should I be checking in order to get my car running again. The immobilizer unit on the car is preventing the car from starting. I've tried the Key in on position for 1 second. 5 seconds off/repeat. Still no luck.
Any help would be much appreciated.
