No primary voltage need schematics
 

Can anyone help me get the ignition chematics for a 4.3ltr 2000 blazer with EDI ignition?

I just changed the timing chain and gears on the truck, and may have wiring problems because I had to raise the engine to remove the pan. Any help will be welcomed, Thanks.

What parts of the ignition system do you require schematics for. My references have it split up by sensor, etc, not a whole system diagram...

Also, you could always consider a subscription to AllDataDIY.com.

I'm interested in harness from Crank positioning sensor and coil/control to PCM. I'd like to check for voltage/ohms in these wires.

I was able to locate one diagram that has all of this in it.

Super! Gotta work today, but will hit the garage tonight to begin troubleshooting. Suspect the PCM is going, but had no codes to that direction. I figured with the amount of miles, it'd be a safe bet the timing needed a going through.

Man, that was a tough job!

Thanks Swarty!
