89 legacy starts but dies

[r0gera]

Here is the scoop.. my 90 legacy sedan blew the throw out bearing and tore up the shaft on the front of the tranny. So pulled the engine out of my 89 wagon parts car which is an automatic, put the torque converter on the engine off good engine and bolted it all back in the 89. Both are EFI and appear to be the same.

 

When I went to test fire it, the thing will start but after starting dies. If I dribble fuel down the throttle body I can keep it running so it sounds to me like an electrical/control type issue on the throttle body. Disconnected the fuel line and there is plenty of fuel going to the engine.. and plenty of flow back through the return line. So fuel is making it to the throttle body but appears that it is not letting anything into the engine.

 

All gauges work including oil pressure (which runs through the same plug as the lines that go to the throttle body)

 

 

What are the easiest and most likely suspects? A fuel cut off valve? Some safety sensor switch? TPS?

 

Should I just pull the wiring and throttle body off the engine from the automatic and replace all that or would that be a waste of time. To me it seems like there must be some type of fuel cut off valve not letting fuel into the throttle body. That motor ran fine before it overheated so it should all be in good shape.

 

This engine was running fine when it was in the 90 and I changed nothing on the engine except adding a T into the vacuum line to run down to the tranny and pulling the clutch off to replace it with the torque converter.

 

Any thoughts?? If I can narrow it down before tearing into it that would be great because am doing it in the driveway in 30 degree weather.

 

Thanks for any thoughts or insight.

And by starts but dies.. meaning.. When I crank it.. it will fire up.. but then when the starter circuit is disabled. it dies out.. but if I feed the throttle body with fuel.. starter fluid or gas.. it will run as long as I dump fuel down it.

did you perhaps unplug something? maybe a missing ground?

Aren't the injectors for the EJ22 in the heads, not the throttle body... so they should have a separate harness for them I think.. Not sure though.

 

Also, this is assuming that you are in the US... which didn't get an '89 legacy anyway, so maybe there is a SPFI EJ22 in other markets that we didn't get??

Yes, can you please indicate whether you're in the US or not.

 

The 1990 model year was the first year the Legacy was offered in the states, and it was only offerred with multi-point fuel injection.

 

Overseas models did get single point throttle body fuel injection....and I think even a carb model some places.

ok.. I am a total retard.. and am blaming it on a long cold day doing an engine swap in the driveway.. they are both loyale's. my bad and my apology for posting in the wrong section.
