Grim, have you found a good double-din screen for a carpc? I've spent a long time looking and they're all crap. All I can find is low quality stuff that you can't see in the day and the touchscreens are cheap resistive films that will fail in a year.
I wish I could find something with the...
No STA signal at the ECU will make for hard starts cold, but it should eventually get going, unless the CSI was also dead, in which case it might be a near impossible start if anything but a warm day.
The reason STA is important is that it will initiate an asynchronous firing of all injectors...
Do you see 12V at the STA terminal at the ECU when cranking? That should initiate an asynchronous pulse of all six injectors during cranking. You should also confirm that the fuel pump is getting 12 V during cranking by monitoring the FP terminal in the diagnostic box with a voltmeter.
An...
The A/T ECU will work with the manual. You will not need/use the digitized throttle position outputs of the A/T ECU.
I suspect there are some other software tweaks between the two, but I haven't done a byte comparison between the two programs.
You need to have the TPS connected. Your mechanic...
The pinion preload tends to be low on used diffs because the pinion crush sleeve fatigues. Easily addressed by replacing it with an aftermarket crush collar eliminator. If the preload is low, you stand a good chance of breaking your diff on a hard launch. The other site has more info on this...

I would suggest to make sure those bolts are high tensile grade as they need to hold that seat in place in an accident.
It is (slightly) possible that if the bearing the CPS is bad, then it will wobble enough to give a noisy signal to the ECU. Since you have a new one, swap it in and see if it helps.
As stated before, there is no diagnostic info in this thread that will allow any hope of a solution. When it happens again, have you DVM handy and start tracing the circuit and recording voltages along the path starting at the battery terminals. Nick already gave you the link to the relevant...
True, but for bolts the measured torque is mostly from the bolt threads sliding against the block threads, so those block threads must be perfect and clean to get an accurate torque setting.
For studs, the pristine stud/nut thread contact area defines the torque, which is why studs are...
It would be highly unlikely that you would get spark and no fuel if it really was a B+ issue. Check the ECU grounds at the intake manifold, they need to be tight. Measure the voltage drop across them with the ECU on (should be small voltage, much-much less than 1 V.
Is the battery getting...
To set the record straight, Siennas 2004-present will not fit and are double din height and extra wide with a curved front panel (unless they have the factory Nav option, which is a double DIN inside a custom bezel). I own a 2007 Sienna so this is confirmed fact.
The previous Sienna model...
Q1: No voltage at CPS. The CPS generates its own voltage pulses.
Q2: What you observe is normal for an off injector with ignition on.
Power (12V) goes through the injector resistor pack and then to each injector. The white wires go to the ECU and are grounded (by a big power transistor...
On every meter I've used the red lead needs to plug into a different connector to read current. Did you do that when making the above test?
If I understand what you are saying, then its reading 8 on the 2000uA scale, which is 8 microamps! The stock pump should draw more like 5-6 amperes!
By...
There are two wire clamps that bolt to the manifold and support the loom. On my car the plastic pieces of the clamp completely disintegrated. I bought new ones when I had the engine apart and I recall there were only 8 left in the US at that time (2 years ago). Probably special order from Japan...
