Ran into a start issue when it was really rainy and wet but started again when the next afternoon after it was been dry. Had original distributor, ignition coil, and ignition control module with 290k on my 97 Tahoe. So I had them all replaced as well as spark plug wires (plugs were already new). Now it sort of seems like the first time I try to start it it will start but then immediately stop but after that its fine. But I got this p1351 code now. I even cleared it after the work was done and it came back. The description says it's "ICM circuit high voltage".
Would a bad ICM cause this? I still have no check engine light and I'm just puzzled exactly what this means and what it will do in the long run.
UPDATE: Went out this morning, cleared the code and took it for a 30 minute test drive. Came home turned it off, started it again. No reoccurrence thus far and no issues starting at all. Is this something that could have just been a little wonky the first bit of starts, etc right after all the changes and had to get all in sync?

I just had the ignition coil, ICM, spark plug wires, and distributor assembly all replaced at the same time, after which this problem presented. Before that, I had a complete no start, no spark condition when it was really rainy but it started fine the next day. I suspected just the coil but had all of the above done anyway since it was all factory original (except wires). I had an AC Delco coil and ICM but the guy I had working on it put in whatever he got (Autozone I think) before I got him the parts. This guy's pretty good though so I would like to believe he'd adjust the distributor correctly (can't guarantee anything of course!!). I'm incredibly leary of that ICM but I want to be sure before I pull the plug on swapping it because once I put the AC Delco ICM on there, I'm stuck with it. Heavily leaning toward the ICM as I stare at a new one in the AC delco box sitting next to me...
