Im having some issues with my car, in the sense that it is having troubles starting up, but when it does it will run for 30seconds-a min and then shut itself down without any hesitation. I hooked a fuel pressure gauge up to the manifold and its showing that its getting good pressure, and my AFR seems good from my wideband. I have no idea why its doing it, but i was hoping i could read the codes on it and see if theres anything glaring at me. The check engine light is indeed on.

So with that said, how do i view the codes in datamaster/how do i interpret them?

Thanks

I'm not sure if you can view the SES codes while in record mode, but if you take a quick data log file while the ses light is on, open the file back up. Click on the DTC ERR , it should be in RED on the top right hand side of Datamaster. It will open up a window with all the possible SES codes. Click the one that is in RED ( two or three may be in red , this means multi codes set) and that will tell you which SES code is set, As well as a short description of the code.

Ok so i checked the DTC error, and the only red box is #36 and reads MALF 36: Hi-Res fail.
I have no idea what this means, anyone help me out?

It means you need to start diagnosing your ignition system, starting with the Opti.

Hope its a bad ICM (which is a common symptom of failure once heated up, as you described)

Hope its not a bad opti, which is most likely.

Here was a thread when I dealt with it:

As he said above thats your best bet...

When i had code 36 it turned out to be a bad opt not that im trying to discourage you but could very well be a bad coil or module.

Opti or opti harness. 36 is for opti signals.

Is there any way to check the harness aside from replacing it to see if its the trouble? I assume its going to be the opti and will forsure not be going with a MSD one. I assume this isnt going to be a rotor replacement kind of thing, and ill have to replace the whole ordeal? Whats the name of the full opti replacement thats worth going with? I remember there being about 1000 write ups on this, ill search through them anyways,
Thanks guys

I had a dead on arrival Delphi.

I bought a genuine AC Delco from Summit which worked.

If you have the cash, I would suggest looking into the EFI 24x 8 coil system. People seem to really be happy with it.

As far as the opti wire goes, they are fairly durable, so unless you see external damage, I doubt that is your problem. They are fairly cheap anyway. One cheap diagnosis is to find a friend with a similar car with a working ignition and swap harness (very easy to do) and see if that fixes your problem. If thats not an option, check these guys:

Thats not to bad, my brother actually has a lt1 camaro so ill try that, but im expecting to shell out for an opti.
It seems like an AC delco replacement is the best bet?
Im a student - so the 24x conversion kit isnt a great idea for me at the time - but just for ***** isnt the cost about 2grand?
