no start CEL Code 12 and constant flashing (misfire?), tried everything kind of stumped Options

[easternpiro1]

Hi all, een having a problem starting my car ever since I got the transmission replaced.

First, the car was giving me a
CEL 12 wiring and connector g2 + signal, STA signal crank position sensor and ECU
14 and 15 wiring connector, ignition coil, ecu

There is also another 14 code listed in the diagostic -wiring and connector, ignition and ecu
Things I've tried:

I've checked all plugs first to make sure there was no significant damage. (Found some on the main harness connector under the fuse box in the engine bay) checked for continuity, seemed fine.

Checked wire going from ECU to crank sensor for continuity, replaced crank sensor to no avail.
I also changed the cam sensor. Car still won't turn over.

We checked for spark and fuel (I'm getting spark and I'm getting fuel as my FPR is reading pressure and in took out injector plug #1 and used a NOID Light.

We also checked for spark and fuel using an old school method by bypassing injectors and putting fuel directly in. The car DID start but ran horribly and cut off shortly after.

Now I have a constant blinking when I pulled codes.

There was NO signal coming from ecu to injector according to Noid light. So it MUST BE ECU? Nope. Replaced ecu same no start but now I'm only getting code 12 and still getting a misfire code (constant blinking)


Does anyone have any helpful suggestions? A bud of mine and I will be tracing wires today but any assistance would be greatly appreciated.


Placham Thanks for the ECU and help so far. I'm sure we can figure this misery out!

Welp.... ALOT has happened since I last posted...


I will get right to the point first....


MANNY, JEN, STEPH, DUSTIN. I LOVE YOU GUYS. I cant thank you enough. I am in your debt. these 6gc OGs are THE EMBODIMENT of what a car community is supposed to look like.

My car wasnt running. Manny and his wife DROVE FROM MASSACHUSETTS to GET MY CAR, AND TOW IT BACK. wtf.... WHO DOES THAT??!!?!?!??


GOOD FRIENDS is who.


dustin and steph... who opened their home to me when I visited a few years back were there to help at the drop of a hat just as manny has since I joined this site over 10 years ago.


once again... thanks guys for helping me.



As a result of their HARD WORK troubleshooting, kicking ideas back and forth etc. after over a year of the Ninja Turtle 2 not running.



On Easter weekend, IT RISES, AND IT LIVES. (ironic for personal reasons)


If you read the first post you will see that my initial diagnosis indicated wiring connected to the CRANK SENSOR. So I thought all along it was a wiring issue.

PLACHAM.... HELPED SO MUCH through this process as well. He sold me an ECU, gave me ALOT of pointers too.


YOU GUYS WONT BELIEVE that after taking out my harness, buying, A NEW CAM SENSOR, A NEW CRANK SENSOR AND EVEN NEW COILS STRAIGHT FROM TOYOTA JAPAN (thanks to a bud)


IT WAS THE ACTUAL CRANK SENSOR THAT WAS BAD.

And all due to a small guide pin that keeps the crank sensor in line by 300ths of an inch from the trigger wheel on the oil pump pulley.

A DAMN PIN!!!

This has been a learning experience and a HUUUUUGE PAIN IN THE ASS for ALL parties involved (tweak'd (camshaft cam in particular )

I have some apologies to give in particular to the shop that I thought messed my wiring up when replacing trans.


With that being said.....


IM BACK..... let the GOONERY RESUME.




See yall later...Im going to church. I also have some apologies to make there too....
