2000 xj loud noise at start of crank - no start

[bobhouseholder]

Hi,
My 2000 xj will not start.
- checked most grounds but need to check and clean the remaining
- new battery from before
- no codes thrown
- new starter
- same problem in neutral (probably not the neutral position sensor)

When I go to start I can hear the right sequence in the key position right before ignition. When starting it cranks maybe once then I get a loud sound and then nothing.

have not tried:
- jump while starting...maybe battery is drained
- CPS ... but no codes thrown

I have searched this and other forums but have not found the same problem reported.

Thanks,
-Bob

It could be lots of things, your going to need lots more info. Scanner data, voltages, audio, video and more are all needed to help with the diagnosis.

Can do. First post so I need to find out how to upload vid to hear sound.

Tried to start with a jump with no change.

13.34V on battery when hooked up to second car.

12.48V battery at rest

That's the bendix on the starter.

The starter is new. Do I need to give it a whack to engage?

It needs changed, if it's new warranty it! What brand was it?

Is a rebuild generally okay? Car quest from advanced auto?

It was not the starter as a second one has same noise. Thoughts?

Flywheel ring gear missing a tooth or 2,... Put a socket wrench on the vibration damper bolt on the front f the engine and turn it just a little then try the starter.

That sucks, a flex-plate is a major project.

I would also check and make sure you always have battery voltage at the solenoid control wire when the key is in start position

update:
- not able to get engine to turn over after rotating a bit...tried several times in case I was still missing some gears
- looked at other new starter that was removed and it looks fine...thinking maybe I sheared off gears on that one
- I have battery voltage both without and with the key in the first position across the solenoid

update:
- found and tested against some of this checklist

https://www.cherokeeforum.com/f59/no...cklist-155216/

- checked a few fuses and do not see anything broken
- did test for ignition switch and that is okay (would not expect this to be the problem)
- not able to check fuel pressure
- hear fuel pump come on during startup
