2G Crank no start

Joh_ecp97 · Jul 8, 2026

I bought my 97 monarch green GSX about 3years ago. About 1 year ago my battery terminal came lose and disconnected. Well after reconnecting it, I had a crank no start unless I unplugged the MAF.

With the MAF unplugged the car runs but poorly idles almost as if it’s running in a limp mode. I know for a fact the cars running DSMLink v2 and I believe the battery disconnecting affected that in some way but I’m not 100% sure.

Could anyway help me with any suggestions.solutions?

Can you connect to the ECU with a laptop?

No, I have the cord to do so but I don’t have the disc or the ECMTuning account info from previous owner

And to clarify I purchased the car with DSMLink v2 already on it. I have the cord for the tune from previous owner but not the physical disc or ECMTuning account info so I cannot access the tune even if I wanted to could anyone help me with any suggestions solutions?

And I’ve attached a mod list as well it’s just a sc I actually own the 2g of another person on here so it’s there mod list I screen captured.

If you have the cable you just need to go to ECMTuning's web site and download the client software. https://www.ecmtuning.com/downloads.php

The 2G DSMLink V2 would loose it's tune if the ECU lost battery voltage so you'll need to find an old log or start from scratch. You might also think about upgrading to ECMLink V3 to get access to the new features and not loose the tune again in the future.
