Jeep will not start, super frustrating
Hey guys I really need some help!
I have an 04 TJ with manual tranny in desperate need of help with starting. She will not turn over whatsoever. I turn the key to the on position and all the dash lights come on, the stereo comes on, headlights on with no dimming. Here's a list below of possibilities I have ruled out:
Battery is new. Optima straight out of the box. Old battery was in great shape. Only a few months of being used.
Battery cables have minor corrosion. About to change them out anyways
PCM has power to it.
Starter relay is good and has power running to it.
Starter is good. Had it tested at auto zone. There is also power to the starter
Ran the wiring harness all around, everything is grounded and plugged up.
Alternator works fine.
Attempted to start with crossing the starter from power to solenoid. Only makes a spinning sound.
Ignition switch and ignition switch with the pin that has tendency to crack was replaced.
Neutral safety switch (I know that's not what it's called but the connection with the wiring harness to the transfer case is what I'm referring to) is good. I also put a fuse in #20 in the fuse box behind the glove box to bypass this and still nothing. Didn't even start when there wasn't a fuse there.
The transfer case was just replaced with a used np231 from the same year, make and model since my transfer case exploded on the highway and cracked open like a coconut.
Had a buddy who pull started me while in 2nd gear so she will start but not by turning the key. All I get is the click and nothing.
I am super lost at this point and in need of help. Any and every suggestions are welcome!
