98 Won’t start after powered sub install.

[Angryfish98]

I just put a powered sub in my 98 TJ. I removed the passenger seat. I drilled a hole in the floor, ran a wire thru and grounded the amp to the frame. After everything was wired, I tested the amp, drove the Jeep around and adjusted the stereo and amp settings. Everything worked fine. I drove it for about 30 minutes. I got up today, pulled the Jeep back in the garage to finish the install. It started right up as always. I had to remove the center console to run and hide some wires. (actually just lifted it, didn’t remove it all the way). Tightened up the console, put the seat back in and tried the stereo. It all worked. ...

Went to start the Jeep and park it and it won’t start. It turns over just fine. Checked all fuses under dash and under hood. All good. Put a code reader on it and got a P032 code. So Electrical?

Disconnected the battery for 10 min or more to see if it reset the computer.

What would make something go bad just from a stereo install?

And also I can’t find a CAMSHAFT position sensor or sync or whatever you call it for a 98 TJ anywhere online. Do they exist ?

Could grounding the amp to the frame with 10 gauge wire cause something to fry ?

Also not sure if I can hear the fuel pump but I don’t remember if I could before. I switched the fuel pump relay with the horn relay and nothing changed. As a side note the relays are impossible to find right now for my Jeep if anyone has suggestions for that.


Thanks in advance, I’m extremely frustrated

Never mind it was the crank position sensor

Glad you found it. Glad you posted it too. Thanx.

No problem

Funny thing is I couldn’t get the Mopar one right away so I put an off brand one in to see if that was the problem. Jeep fired right up after replacing it but it ran like crap and threw a 0391 code. Went to a dealership and got the mopar OEM one and put it in and the Jeep fired up and runs great now.
