Ive been having excessive cranking/misfires and no tachometer for about 2 months now.After looking online on the possibilities of what it could be i decided to fix it myself.First I bought CKP sensors and the problem didn’t go away then I purchased an ICM from ebay and it Didn’t fix the code . I changed the connector C1 harness that clips to the ICM .It’s the one that only has 4 prongs on the connector even though there is a slot for 2 more. Didn’t fix the code 😥
Tried an aftermarket coil pack I had for awhile now .Didn’t work !!
After giving up I took the car to the Cadillac Dealership for a true diagnostic and a mechanic told me it was indeed the wire from my ckp sensor because he unplugged one and left the other in and literally there was no change in my car .So that’s when it clicked to me that the sensor he unplugged never worked since there was no change in the cars performance after it was disconnected .Dealership said it’ll be about $1000 for the wire to be fixed and a new engine front mount added 🤬🤬🤬
I immediately knew I was gonna fix it myself 😂 Took a drive from NY to PA to a pull-a-part and took the harness off of a 98 Deville and plugged it up to my car tonight after cleaning the wire of course and adding new loom/Electrical Tape
CAR STARTED UP WITH NO PROBLEM!
The pull-a-part place didn’t charge me for the harness either. WIN/WIN

Instead of running the new wire behind the hot ass exhaust manifold again I ran it from the ICM ,past the air box,over the oil filter and right into the crankshaft sensors .
