what's your fuel pressure reading at the Schraeder valve?
you got the plug wires routed correctly?

Get a fuel pressure gauge, hook it up to the schrader valve, turn the key to the on poistion and see what pressure it is putting out.

yes, it looks like a bike tire valve. Put a rag under there because you will get a small burst of fuel when you connect the fuel gauge to the valve.
take two readings:
1) key on, engine not running
2) engine running (at idle)
report back
