Default Vortec no spark

Died on me going downt the road in Windsor Ontario. Im an american used to parts stores being open most of the time Saturday and sunday. Everytime I want to go to Autozone in Detroit, have to cross the border, pay bridge fee 5 dollars in each direction. I think there is only 1 part left in the whole system that I havent replaced, the ICM, but I dont have much faith in it. History of vehicle, no start 2 months ago, replaced distributor, ran but had a misfire on number 6, replaced spider fuel distributor, ran great but still threw code PO300, drove 1500 miles, ignoring Check engine light flashing. Finally just shut off going 70mph. I did notice a longer start cycle a few days before this. No codes thrown, have replaced the fuel pump, coil, cam sensor, and crank sensor. Ill run diagnostic on ICM, but I hate using meters on wires, it seems kind of not definite information I am going on. BTW, rotor is turning, not a broken timing chain. I did have a crank sensor go out on me 2 years ago, on this vehicle while traveling, had it fixed by a shop. I have had success with the CMP correlation error p1345 using a bluetooth adapter from Amazon and a little app on my phone.

ICM is a fairly common failure on these.
