I adjusted the TPS and the car runs (poorly), but only if you constantly pump the throttle. If you hold it down, steady, or idle, it dies. Anyone have any experience with something similar? Thanks

I checked for voltage at the injectors, and it is present. My thoughts right now are that there is not actually fuel in the fuel rail, or the injectors are not getting the proper signal to control flow of gas. When I was spraying in the gas by hand, the throttle position change made absolutely...

Well I made some progress. By pulling the intercooler tubing on the intake and spraying gas in by hand, it runs. I can hear the fuel pump, but don't know if the injectors are clogged or not getting what they need to operate. Easiest way to verify??

Any ideas out there guys? I was hoping someone has run into something similar. Thanks

So I got a Map Sensor and plugged it in. No more codes being thrown now, but it does what it did before, turns over, pops an couple of times, but no run. I am checking the wire colors, since they are different between the map sensor connectors old and new. Don't think that's going to be the...

I didn't realize that would affect the cam and crank signals.

It appears the connector for the MAP Sensor is on the passenger side of the Soarer 1JZ wire harness. Definitely no sensor in sight, but the vacuum line is in the area. Still no idea why the crank and cam sensors aren't being seen, as the ECU wiring was left intact (other than splicing in about 3...

Thanks for the picture, that helps. The Map sensor is not there, but I will look for the connections.

Wow, those MAP sensors are spendy..... ---------- Post added at 01:42 PM ---------- Previous post was at 01:40 PM ---------- I have not found the plug for it yet.

Found out the NE signal is the crank sensor and the G signal is the cam sensor. Going to scope out if the signal is getting lost on it's way to the ECU. With the thin information out there for soarer 1JZ wiring conversion, anything is possible. I noticed that the ignitor I bought for the 1JZ...

Can't find the map sensor. Is that something I needed to buy with the switch over from the 7M NA engine? Also, exactly where does the "NE" and "G" signal come from, so I can trace it to the ECU?

Have to do some exploring for the map sensor signal. The codes say what I am missing is the RPM signal and the Air Flow meter signal.

Went and checked it out this morning. It is throwing out a 12 and a 31 code. The 12 code makes sense with what we are seeing. The 31 code was a surprise. I looked at the inside of the ECU, and everything looks brand new, no leaking caps or corrosion. Any suggestions on the trouble shooting part?

Thanks, I will check it out tomorrow. I hope it works with the ignition only, as it won't fire up to check while running.

I'm afraid you will have to help me out here. New at the Supra thing. I am very familiar with OBD2 codes on my reader with the newer cars, but not with respect to anything from 91. What do I need to do to check for codes here?

Just finished putting a 1JZ (soarer) in a 91 Supra. Needed to run the thicker wire to the solenoid and now it turns over great (didn't before). It pops and sounds like it wants to start, but will only go for a few revolutions. I keep trying things, but no luck yet. Anybody have any experience...

Yeah, I tried the photobucket thing, but it's not working. I have a picture on my desktop, but its not easy to put it here. I will try the photobucket thing again.

The canister is just to the left of the circled area 1. It is on the other side of the intake. ---------- Post added at 08:53 AM ---------- Previous post was at 08:52 AM ---------- http://s1084.photobucket.com/upload/albums/tmarkco/

On the pictures of other stock 1JZ motors, the blowoff valve has a small cannister and hosing that seems to be for recirculation. It is missing on my engine. Any idea exactly what it does, and can I get by with some work around?

There is just a bolt on the end of the manifold. I will pick up a 3/8 inch nipple and plumb it in. Thanks for the help.
