I've cycled the key several times to no avail. That was done to eliminate the fuel accumilator. I have not pulled the cold start injector partially out to see if it spraying only because the engine is fine if at cold start I manipulate the accelerator pedal slightly. The engine readily goes into cold idle after this.

Have a look through the secondary side of the ignition system; condition of the distributor cap & rotor, wire connections, wire condition, and spark plugs clean & gapped. Faults in the ignition can be mistaken for injection faults, particularly during starting.
By opening the throttle slightly, the sensor plate is deflected a bit further, thereby providing a little more fuel.
