Code 12 is the RPM signal. This thread is worth looking at. It won't take long to pull of the lower cover and check everything is fine with the lower gear.

It sounds like the ECU is not getting a signal from...
That is what I was saying. You are not getting any ground to your injectors.
This relates to two different things. Sensors or ECU. You said you had the ECU tested, so we are going to assume it is in working condition.
The sensors that control the spark and fuel see the crank and cam...
If you had the ECU tested, then lets assume it is fine right now. You will need to try and get to crank the engine and see if you get a ground at one pin of each injector plug and it should be pulsing.
You can go to Harbor Freight and get a NOID light kit. If it blinks, you are getting...
Both pins are getting 12 volts? Ground is only sent when cranking and the 11.xx volts is fine at this point.
Was your car running before? Both pins should not be getting 12 volts, only one wire should be getting 12 volts.
Was the test done while cranking since that is when the ground is...
I agree. After I finish this IJZ rebuild with all the nice HKS performance stuff, it will be worth a good amount. I actually know a few buyers that will be interested.
If it does get sold, I am getting a 240Z and doing a 2JZ rebuild singled swap along with a silver paint.
In my opinion, the...
Well, just saying, I had my charge pipe off and it read zero on my AEM gauge.
So the leak has to be one of the two intake manifold gaskets or the throttle body gasket. Replace all three at once so you won't have to worry about it.
You should have 17-22HG for your vaccum reading at idle. If not, you have a major leak in your intercooler piping, intake manifold gaskets or your accordian hose....
I believe he is trying to say after the feed since, the fuel flows to the return and there is pressure there meaning the feed side is sending fuel, it flows through the rail and goes to the return side where he probably pulled the line or maybe has a regulator there.
Let's wait and see what he...
Full of Win here.
Look what this DoucheBag did, he report this hot babe. The father must be retarded saying it was a "traumatic experience" for his son.

Noid lights won't work here. They need both 12v and ground.
If the ECU is allow spark, it should be allowing fuel by grounding off each injector.
I asked the OP to check to see if that is happening, if each injector is being grounded, which the ECU does, and there is no 12V signal, then it...
Well that means your cam and crank sensors are sending a signal.
Check to see if when your ignition is on, that you have a constant 12V at each injector. If not, have someone crank the engine, check both pins. If you are getting a ground on one pin when cranking then your injectors are not...
Have you driven an E38 when it is cold? It drives different, a lot different. In the manual, it says to drive away at a slow moderatore speed until the car is fully warmed up as well.
Like what Poodles said, I don't like the short road trips. If I know I am going out, I always start my car up and let it get to operating temperature. I do it on my Supra as well. It is call "Operating Temperature" for a reason.
I don't understand why it is bad for the oil but I always...
