OK. I was thrown when you wrote "I fried my ecu." It seems like now the ECU may not be the culprit? From experience, loosening the fuel line banjo bolt results in a short but big spray of gas.

Spark/fuel/compression. Pull a plug wire off, stick an old sparkplug into it, lay it on the valve cover, crank the engine. Nice blue/white spark? Pull the hose off of the throttle body and spray starter fluid into the throttle body while a helper is holding the gas pedal halfway down and cranking the engine.

I have spark and the starter fluid didn't do it. When I pull the banjo off the gas just sort of gently flows out. Not huge pressure or anything.

I just pulled the plugs again and tested for spark, all four cylinders are getting spark, also there was fuel on all four plugs. It seems like it wants to start but no luck.

What if the spark is just weak, would that keep it from starting?

Also now the D4 light comes on when turning the key and it didn't before.
