My blinker doesn't work sometimes so i'm going to buy an opti .
...

JUST KIDDING!!! But you're reading this now. My car recently would not start up. Ended up replacing crank sensor, ignition module, coil and the opti harness and it started! It will run for 10-15 minutes on first cold start up before dying, after that wont start up. After sitting for a few minutes, it will start for a few seconds. After sitting for awhile it will start for a few minutes. I have fuel. My buddy hooked up a pulse checker? blinking light and we tested spark at the same time. Both the pulses and spark cut out at the same time and engine dies. Due to the lack of response from another post of mine we (after checking with a 3rd buddy) are going to replace the cap,rotor, distributor and wire set. Throwing a code p1371 distributor ignition low resolution i believe.
Am I on the right track or no?

No matter what the problem is with your 93-97 LT1, if it wont start, misses, down on power, has bad brakes, pulls to the right, window wont roll up, t-tops leak, girlfriend left you... its the opti spark. Just change it. If it dosent fix it, youve got a dud. Change it again until you get a good one. Sometimes it takes a few, but eventually you should get one that will at least last 6 months.

I had that same problem with my 96 T/A, it would shut off and i had to wait a while to restart, changed out everything that I thought it may be and 2 opti sparks, because i didn't put the first new one back on when i thought i had put it on wrong new fuel pump, relay, coil and it ended up being the Crank Position sensor, which when it went back it sent full volts back through the system and fried a few fuses. also I couldn't get one of the pulley bolts back in straight son the shop had to re-tap the threads and to get it running again cost me $1100.00 plus all that i had spent trying to troubleshoot it myself.

Full synthetic baby
Yeah, i'll update tomorrow with the replacement.
Damn, I do have a new crank sensor in it but I was under the thought that would do nothing but throw a code?

Look at the ignition switch on the steering column to see if its burnt up. This is a very common and overlooked issue with alot of lt1 fbodys! Mine would start when it wanted to and then wouldnt start for the life of it. New opti, coil, module, etc still couldnt get it run properly. Checked the ignition switch and it was fried. Would only get a decent contact when it wanted to causing it to start when it wanted and even when started it still wouldnt run smooth without misfires.

After some more digging now that i'm home looks like i need to drop the steering wheel and i'll see it? I have a question, what would cause that to burn up, just from being old and used or is it some design flaw? Would this also possibly cause my problems. If it isn't the opti i'll be pissed.

also for a better idea, hook up to the ecm. watch and see if its cutting off when its going into closed loop operation. by the way your describing your issue, it sounds like that closed loop operation is a issue. that can lead back to a few different sensors but like the other gents said "the low res code is an opti issue" . so deal with that first.
