Since I got a reflash, can't start the car... ( didn't change parts yet after the flash )

Is that a P0300? I just turn key on accessories and it does that:

That doesn't sound like a p0300. Have your ECU flashed back to stock and see if that cures your issue.

 

I started getting the random misfire code the day after my 272's went in. I never had it while I had 264's. I'm holding out for a couple mod mods and then just getting retuned and hopefully getting my idle smoothed out a bit. Mine only kcks on if it idles for a long period of time.

My car idles like pure JUNK right now....

 

I just got my car back from getting a ton of stuff done to it and my p0300 came right back. It's been an ongoing battle for the last year or so.

Iam going to do some of the recommended checks that the FSM describes. If everything checks out i am going to get the P0300 flash.

 

do you mean a 'dealer' reflash or a 'performance' reflash?

 

I leave oversea, take maybe 2-4 weeks via Fedex to send it and get it back. So hopefully it's a bad reflash and it will be done right.


"Performance" reflash

 

ok, next question. Did you recently have flash for the p0300 code by the dealer? If so who ever did your flash is going to owe you a new ECU because it is now locked.

 

ECUs are programmed to the chip in the ignition key that came with the car. If you've swapped ECUs they won't work.

You will have to go to the dealer and have them make a new ignition key.

 

No I didn't, what do you mean by locked? No one try to start with my ECU ( normally ) except me with the same key that came with the car. Unless the guy who did my ECU install it in his or one of his customer car and try to start with????


Didn't swap ECU... hopefully the security thing that lock the ignition is not the case... cause I have no Mitsubishi dealer here.


Argh you are scaring me...
