[T3] New pump different hic-ups

I've had problems with sticking injectors several times over the 
years. Sometimes it clears itself and sometimes not. Usually I can 
get everything working so I can drive by doing the following:

Start the engine. Note that it's just running on 3 cylinders because 
one cylinder is flooded. To get around this, with the engine running, 
reach under the dash and carefully wiggle the white plastic plug 
slowly off the back of the fuel pump relay. Do this slowly, until you 
hear the "click" from the relay indicating that it's not running the 
pump any more. Hold the plug still while the fuel system pressure 
slowly decreases as the engine continues to idle.

At some point, the pressure will drop to the point where the flooded 
cylinder will clear itself. This is usually accompanied by the idle 
speed rising slightly, just before the engine dies from lack of fuel.

If you still have the plug in the right position, push it back on the 
relay. If you time it right, the engine will begin to idle on all 4 
cylinders and you can drive normally. This all takes some 
coordination and practice, but I've been doing it off and on since 
1968 and quickly learned how to do it while still sitting in the 
driver's seat.

Try it.
