Without an actual voltage test we don't know for sure if it is actually at 0.5v(?) or much lower.

But after he said he swapped it to test and it looked fine I stopped asking him to look at it.

Hopefully he gets it fixed up and lets us know what the issue is.
But he said he DID test it but wouldn't divulge the results.

I'm always anxious to help but this is wearing me out.

I think his test ended up being just swapping it to a different vehicle. I haven't seen any indication he got a voltage reading off of it.

He can confirm what test he did though whenever he pops on next.

If so, that's not a good test. The CPS must be tested with a meter set on AC volts, unplugged, and installed on the vehicle with the issues.

That doesn't mean the CPS isn't bad though. He never actually tested it for weak voltage.

I think he's got a mess on his hands.

We're trying to do brain surgery over the internet.

Alright I am gonna list what I did today to get spark (of which I did not get). But before you all go saying I didn't listen or look at stuff you must know that I have had no connection to the internet all day. Wifi fried and had to set-up a new one. Alright on to what I did....

* Pulled the CPS and cleaned around the area and put it back and tightened.
* Replaced Ignition coil to distributor
* Pulled Distributor cap to checked for damage or corrosion (none)
* Checked fuses under the drivers side AND next to ignition coil

What I noticed while doing this...
* There is a set of wires that runs from the starter up to the Distributor that from there attaches to a plug in under the Ignition Coil. Could this be my problem?
* My alternator doesn't look as "new" as the owner before (my cousin) me said. Could this be it?
* The Jeep stopped running after I gave it some gas (while it was dying, when clutch was engaged) and a large cloud of Black smoke exited my exhaust. I then had to use the starter to back up my jeep in reverse due to weather and myself being alone. Could I have fried the wires that run as aforementioned. I know my O2 Sensor is old and has never been replaced. I have heard conflicting answer of it no giving spark and it doesn't matter if the O2 sensor is bad. Could this be a problem?
* I had my dad stop down and help me. We tested the CPS and it came up as 0.6v. I then called my friend who said the same when we tested it. I made sure it was tight.

That's what I did today while waiting for my internet to be repaired.

Well there's a red wire there with a plug in on it that's not plugged it. Also there was a blue wire that was supposed to be connected across the motor. Close to the fire wall. Other than that...The negative cable is charred and exposed. Would that cause a crank no start? And those wires I mentioned in the last post.
