Well I got a free '95 celica STX, put in a used 7A-FE. Fixed it up and sold it for about $2600. I had a gen1 engine and some spare stuff, I sold it as well. Used the money to afford a gen3 swap in progress. Pics up later today.

holy crap I've never posted pics or progress not a bit huh? well that's gonna change soon. I have the gen 3 in. found out I had a blown ecu. got a new one from mr2 guru... still no start conditions. codes... 22, 23, 24, 31, 41, 54 yeah. I know the 54 and 23 issues and will be solved soon no worries. but... there is still no fuel ground pules from the ecu, everything seems to be checking out except some leaking voltage only present when ecu is unplugged. and still remains after sensor plugs are out as well. I did the harness myself using the two harnesses combined. using botch sets of schematics. and the sensors that are part of the center plug on the ecu plug are throwing codes. the ignition is perfect and sparking normally in rythym. the compression is 180 across the board, so valve timing is not it. all grounds have been tested for leaking voltage and resistance. checks out as well. I am just going to pull the harness soon if I cant figure it out while it's in the car. it's driving me crazy, but I have to get it to run, it idle'd twice for fifteen seconds each. which means it's trololoing me for no reason. oh and relocated the battery as well.

harness is back in after the third attempt... pretty damn sure everything is perfectly in place now... it fires under it's own power... but idles and dies after a few seconds every time after I let it sit for a second. i took off the fuel line at the filter and pinned the pump to run full time... yet the pressure seemed to be lacking, it's supposed to be at 50-60 psi, yet it looks like a grade school water fountain... perhaps the starting is actually from the residual pressure being built up...
I suppose I will go through the every connection in the ecu and body harness and look for errors... bleh

stock fuel pressure is 37psi FYI, also the fuel pump isnt going to shoot as much fuel as you think. About enough to fill a 2 liter bottle in a little less than a minute.

I have refused to update this thread because I haven't been near the car in two years, I recently had it shipped to me in Vegas and I'm finally able to make some progress, I'm where I left off before. Gen 3 swap is in, ecu still not firing ground pulse to the injectors, after some very thorough testing I discovered a few alarming resistance values in the efi circuit, namely the center plug sensors. The have standard values when tested against the e2,yet they all have zero resistance on them all. The ignition functions normally and spark is strong, I can still get it to idle for a few seconds due to residual fuel fumes in the cylinders. Injectors have proper resistance 2-4ohm.

I pulled the harness and am testing all the sensors that gave wrong resistances and so far the tps potentially is not functioning right. I will retest with my back up
Mm. I will hand trace every wire according to the st205 ecu schematics (although the 185 sensor ground loop is different) and test resistance between both ends. Grounds again will be checked. The ecu body and ignitor as well ground will be checked. If everything checks out and I still have this same issue I will buy another 205 ecu and make sure it isn't the ecu (even though this ecu was supposedly working) as we I would like to send the ecu to anyone with a 90 usdm 185 with a Gen3 swap

Just so I remember I am making progress on other areas this is my gauge mod I've done so far, lots of led's all custom fit so there is limited hot spots, and I used a combination of the gts and all trac set ups to make this, no more useless boost meter, and yes its plug and play if you use the flat wiring from the gts.

Yes I am using these wheels, maybe not exactly fitting this way but they will work and there isn't any way to convince me not to.

Also working on custom body extensions all around, this is my side skirt rendition still in fab mode on everything but great stuff so far.
[attachment=-1]uploadfromtaptalk1395660669818.jpg[/attachment]
The rear I'm using a stock rear bumper cut up and filling in the repeated body lines, still work to do of course have to work on getting it to fire first.

[attachment=-1]uploadfromtaptalk1395660849847.jpg[/attachment]
I had a set of convertible mud flaps to add and they wrapped the new skirts well, not sure if I'll use them yet, the sides were made using Volvo s70 sides hacked up.

Because injection timing is based on engine rpm, the ECU must receive an rpm signal to operate the injector driver circuits. With Conventional EFI, this signal comes directly from the coil and is identified as IG. With TCCS, the rpm and crankshaft position identification signals come from the Ne and G1 sensors located in the distributor. If these signals are lost, the ECU will not pulse the injectors.
This is the best answer I've found for a no injector ground pulse.

Input Signals Required to Pulse Injectors
There are three signals which are necessary to operate the fuel injectors. These are the Ne, G, and IGf signals. Inside the ECU, the Ne Signal is used to produce an injection chive signal. The G signal is used to determine the timing of the injection signals. The IGf signal is monitored for fuel delivery fail-safe. (With Conventional EFI, the IG signal is used to produce the injection drive signal.)
The ECU cannot pulse the injector without an Ne signal and will not start or run if this signal is not present. If the G signal is not present while cranking the engine, the ECU will not be able to identify when to produce the injection signal. The result will be the same, no injection pulse. If the IGf signal is not present, the ECU will go into fuel fail-safe by stopping injection pulses.
If, however, the ECU loses the G signal with the engine running, the engine will continue to run because the timing of injection signals is locked in once the engine starts.

You said way early in the thread that you extended the injector plugs.... I don't think that's a coincidence.

That was on the original harness, not on this one, plus there is no pulse from the ecu, please explain how a small extension with zero measured resistance would prevent a simple 12 volt circuit from being completed?
Voltage at the injectors is fine, also is the injector resistance. The point here is that the IGF signal is likely culprit here, when the signal is lost there is a full cut, it's the only condition I can find where spark remains and pulse is lost.

i thought igf was to determine if the cylinder spark was fired or not! i guess igf also determines tacho output as well!. i would say double check continuity from injectors to ecu plugs. injectors are fired by the exu grounding them. other wire on injectors are ran by 12v, but because of the injector resistor pack, that voltage varies? do you have a resistor pack in ur harness?
