I have the engine back in the car and I've connected all the wiring, fuel lines and vacuum hoses. The engine turns over but sputters and won't start. I have spark, fuel, but have not checked the fuel line pressure. One thing I noticed when connecting my wiring harness, the injector plugs and the MPS plug have chamfers for, I assume, one way fit. But mine will just as easily plug in either way. Can someone direct me to a photo, detail, or description of the right orientation?

I don't think you have an issue w/ trigger points or anything else electrical. If it starts and ran after spraying starting fluid I would look at a fuel delivery problem. Crossed return/pressure line; crap in tank or clogged fuel sock or fuel filter; fuel pump -what pressure are you seeing and is the pump running? Do you have the flow chart to check your fuel pump circuit?
