Replaced the battery? Cleaned the battery terminals? Checked the grounding? Made sure it wasn’t the alarm or immobiliser?
If your car still isn’t turning over still then the starter motor is most likely to blame.
I recently went through this process of elimination with my Nissan 200SX S15 Silvia and it all came down to a dead starter motor. Technically, it didn’t look like there was much to swapping it out but since there wasn’t much detailed information out there it made it just that bit longer and harder (ahem).
So to help you guys out, here’s a guide on how to change it on JDM 200SX S15 Silvia, I’m pretty sure it’s similar for most other Nissans within the family as well.
- 14mm socket/spanner
- Jack Stands
- Pliers (optional, to assist removing cables)
Duration: 2-3 hours
Profanity level: High
Note: Buy the correct replacement starter motor. S13 and S14 starter motors (part #23300 65F01) will bolt up and work in a S15 but from my experience (and wasted efforts) it will not physically fit through the gap between the bellhousing and the steering shaft. There is about a 1cm difference in diameter which will make all the difference when trying to squeeze it through. JDM/ADM/5spd/6spd/Auto S15 starter motors are all the same so get an S15 one to preserve your sanity (part #23300 80F00).
Disconnect your negative battery terminal.
Jack the front of your car and put it on jack stands.
There will be two cables attached to the end of the starter motor, remove the nut on the one that goes to the battery terminal (it has a rubber boot on it) and detach the cable, repeat for the other one which is the ground.
There are 2 x 14mm bolts that hold the starter motor in place to the bellhousing. They are located on the bellhousing itself behind the starter motor instead funnily enough (hopefully this saves you time because I was scratching my head wondering how I take the bolts out from the front). The top bolt is in a tight spot to get to, but with a small ratchet it is possible.
Time for the most time consuming part which is wiggling the starter motor out between the steering shaft and bellhousing. It will take some patience and bumping around but ideally you want it in the position below where you can just angle it on the edges and it will slide out. Take care not to damage any hard lines or hoses.
Before you attempt to put the replacement in, look at the dead starter’s gear position and try and adjust the gear of the replacement one to be the same. Not the end of the world if it’s not identical as you can adjust it later, just nice to get it all in one go.
Slide the replacement starter motor up arse first and angled just the way it was taken out and proceed to line it up back into position to bolt it back together.
If you’re having trouble getting it to sit flush, chances are the starter gear and the flywheel gear are not lined up properly. Rotate the starter gear slightly clockwise and try fitting again, trial and error will get you there.
Tighten the bolts up again and attach the two cables to the top of the starter motor again. Remember to attach the correct cable to the right plug!
Reattach the cable holder which was removed in #4 and carefully reattach battery terminal.
Start her up and smile as she comes back to life.
So there you have it, hopefully it didn’t you too much grief and you saved a lot more time than I did figuring it all out! Save that money that would have went to a mechanic for more useful mods!
