Red Wire Hanging Near Battery, '90 C4 Cranks But Won't Start (Photo Incl)

[DefinitelyMiami]

Hey all,

C4 drove fine last night. Went out this morning, and it cranks but won't turn over. Popped the hood and saw this, not sure what it is/if it's related. It's a red wire hanging down near the battery. Any help would be appreciated- this is my first Vette! I bought it only a couple of weeks ago. 80K original miles. 1990 C4.

Update: Looks like that was just a cable for a sound system that had been previously installed.

Update: Looks like that was just a cable for a sound system that had been previously installed. I've isolated the issue, and I believe it's the ICM. Going to change it tomorrow and hopefully it fires right up.

Update: Is this the culprit? It leads back to what I think is either the MAF Burnoff Relay or the MAF Power Relay, and I bet it was connected to that terminal.
