What wire is this?

My Jeep is not starting. Starter engages but engine doesn’t turn over. This wire is split and i have simply crimped it together for use. I have been trying to track down the culprit of why my jeep won’t start.

That is the power lead that triggers the starter solenoid when the key is turned. If the starter is engaging your connection should be ok, but check the integrity.

What is the condition of the battery and terminals, for starters disconnect, clean and re-tighten the terminals.

If the starter is spinning but not engaging the flywheel/flexplate, then I think the starter would be the first place to look.
The large wire should have constant batter voltage and the smaller one only has voltage in the start position of the ignition key.

The solenoid that is a part of the starter assembly performs two functions.
Applying power to the windings of the starter motor and energizing a solenoid that moves a lever that pushes the starter motor gear into the flywheel/flexplate.

As always I very well could be stating this incorrectly and I am completely off base.
 
“Starter engages but engine doesn’t turn over.”
We need to make sure what you mean by this statement. To some of us, that would mean the engine is seized and not allowing the starter to rotate the flywheel.
Does the starter make a different sound than what you are used to? Is the belt and pulleys spinning, but it just won’t start?
Not trying to be difficult at all, but I’ve heard people say, “It won’t crank over” and they mean it won’t start. Or, “it turns over but won’t crank”

Could be your ignition, grounds, bad starter…

It does not make a different sound and everything is rotating. I am starting to think i am having a fuel issue since I put my foot on the gas while it was cranking and my jeep began to spark and almost turn on.
 
If it’s cranking then you certainly don’t have a starter issue. And if you’re hearing / feeling a difference when you give it gas, I’d lean towards checking spark first. Fuel could certainly be the issue but I’d start with fire.
 
Maybe squirt a little starter fluid down the throttle body. If it starts and runs for a second or two it more than likely is fuel related.
Being fuel injected, I wouldn't think doing anything with the throttle (I put my foot on the gas while it was cranking) would make any difference.
I'm sure you ruled out empty fuel tank?

This in-line spark tester is under $5 at Harbor Freights. Simple and effective.

Keep us posted.
 
Would a bad power lead cause everything to die when I turn my key? Having an issue where sometimes if I turn my key to on everything just dies like I had a dead battery. My battery is fine and If I reconnect the battery than it will start okay for a while. I am starting to think I got a set of dud cables from CustomBatteryCables. Gonna clean all the surfaces and reconnect the cables and see if it helps.

Sounds like a bad connection, clean and tighten, battery cable ends and cable to terminal connection, starter connection, ground cable at engine block & firewall. Also check the power wire at the primary junction box (fuse box) under hood by battery. If it is still not fixed use a voltmeter to check for a voltage drop. Set to voltage auto or 20v setting. Attach one lead to pos cable at battery and other lead to the positive cable at the starter turn on or start and read the voltage drop. It should be less than 0.5 volts. Then test negative cable the same way. This will isolate the amount of voltage lost through a cable or connection under load. You can go between each connection to isolate the bad one this way. Ie. battery post to battery terminal, terminal to cable. Cable end to cable end. Ect I use to find a lot of explorer cables that would loose 12 volts in the first inch of cable at the terminal this way. Could nod not see the corrosion from the outside but one voltage drop was verified I could cut open I see all the internal corrosion. I hope this helps.
