GTS swap will crank, start for a second, then die

I have an 86 sr5 that I've swapped in a bluetop out of an MR2, and replaced the wiring with zenki engine bay (chassis) harness, and kouki engine, underdash, and rear car harnesses. When I try to start it, it cranks, fires up for a second, then dies. Does anyone have any idea what could be wrong?
Here's a video of it happening. http://youtu.be/vo5XCVMksjY

The engine is running off the cold start injector. Check and make sure
you have 12V at the injectors when the key is in the ON position.

There is a common ground for the 4 injectors. Look for 4 wires "brown" connected to a single eyelet, make should you a good connection. You may be able to feel the injectors pulse thru your hand, while someone cranks the engine to see if they are getting a signal to the injectors. 2nd option is to get a noid light from an autoparts to verify the signal. Most VOMs will not read such a short voltage signal. Dave W7

I was indeed getting 12V, and pulse, as verified by Noid light. Turns out my injectors were clogged.

That was all hooked up. It turns out my injectors were plugged.

Thanks for the replies, guys! Now to figure out the trans. :roll:
