Starting issues after clutch install. - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

itzaustin · 01-17-2021, 07:43 PM

Hey all just got a quick question to see if anyone possibly had an idea. So just finished up on installing a new flywheel, clutch fork and pivot into the car. Second time I’ve done transmission work on it. Got everything back together fine, started up the very first time no issues at all to test everything out and it started up and worked fine. Parked it double checked around for stuff noticed the two wires on top of the trans weren’t plugged in so I plugged them in. Went to start the car up again after and nothing. No crank no start no clicks. Only similar issues that sounds like this is the clutch switch going bad causing the car not to start. I’m going to order one and go from there. But if anyone has some insight go ahead and let me know!!! Thank you

Loose battery terminal?

Two plugs on top of the trans are for switches I think -- reverse switch and one other.

edit: other is neutral switch.

You should be able to test the clutch switch with a multimeter easily. Seems too coincident with the work you just did. I'd lean more towards something in/around the transmission tunnel

Bubba suggests to unplug those two wires -

Is it possible you plugged those two wires in the wrong place (reversed the connections?). Maybe swap the wires and see if you still have the same issue(s)?

The plugs are keyed differently. You would have to go in there and cut the tabs off the plug to make them interchange.

I figured, I was looking for some spec sheets/docs to prove it.. pictures of the harness on ebay etc its hard to tell.

Next thing I would try it disconnecting the battery, and re-seating those connections, then reconnecting the battery and trying...

I just went out and looked at my spare trans to verify. Black plug has tab on left(looking at trans from the front), brown plug has tab on the right.

Yea tried unplugging those again that were off prior to the issues and there is no change in starting, as well as disconnecting battery re seating them and then trying again. The one thing that just throws me off is the fact that it started once already, and then it won’t start again. When I hit the push to start the console screen as well as my gauges turn off and back on as if it was actually starting like normal.

Have you checked or jumped the clutch switch?

So, have you tried unplugging those two and trying to start it again while leaving them unplugged (same circumstance as when it started the first time?)

Sounds like dead battery?
