20v starts-goed 10feet-dies

I'm sure glad I found you guys. I am at my wits end and no one over at that other site has helped. I've just completed a silvertop into my '85 MR2 using (altering)the harness and ecu that came with the motor. It started right up and ran well. It idled, I could rev it up, I couldn't wait to drive it. It had taken me three weeks on one of the hardest projects I've ever attempted.
I went inside, cleaned up, changed and went out to drive it. Started up, let the clutch out, engine dies and won't restart. I still hear the fuel pump, still have spark,no injector clicking. It did start one more time but would not rev. I felt the injectors clicking, about a minute during which time it would not let me rev it at all. Injectors stopped clicking, engine died about 5-6 secs later. What do I check next? Bob('85 since new)

Theres a couple of things that this may be. I have a similar problem, ecxept mine just runs extremely rich when it finally goes. Try the AFM, the Temp sensor (The three wire one on top of piping, before the thermostat), or the flow relay (the yellow bit under the throttle bodies on the air intake side). I have yet to try this on my own, but i definately have a click coming from one of the three that is causing the same problem you are experiencing, only mine is only apparent at startup.

Check for lose wire. You might have missed some ground wire. Once I put the bolt on and didn't tighten it. Once the engine start the wire bounce on and off. Took me long enough to figure that out.

I think checking the grounds suggestion is good because when cars do weird things it has to do with electrical connections and grounds. Also is there a difference in the cylinder positioning sensors. CKP? CYP? TDC? i am not familiar.
