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!

You want power but have no money. That's a problem.

Cheap. Reliable. Fast. Pick two.
