my motor is an sohc motor in a 1.3 4cyl. 95' geo metro...it is able to start with the fuel relay pulled with priming into the trottlebody, but what ever controls the fuel released by the injector, has failed...but with so many sensors, where does one start to ck for faults, does the vacuume control the amount of fuel forced through the injector, if so, what would be the most conspicous of them all???I am trying to get this vehicle running for my parents because they are disabled, and like all, they have dr. apps. all the time...that is why this question means so much to me...and I will reward the one answer with a golden opportunity...to my archives of un-soliceted video...of extreme motor sports, and special, very special bonus features....I am for real....and my word is my bond... lordclawson@yahoo.com...for GoodTimes Media...out of Rockwall Texas...lookit up if u have ur doubts, but I'm really just concerned about getting my folks back on the road...tell me what you think...peace.

The fuel pressure is kept constant by the fuel pump and fuel pressure regulator.
This being the case the computer controls the amount of fuel delivered through the injectors by controlling the opening time of the injectors, this is known as the injection phase and varies from about 0.5 millisecs to 10 millisecs.
The only way you can get a flooding condition is if the injectors are held open for too long. The things that can cause this I will list.
Blocked or jammed pressure reg (press too high).
Faulty coolant temp sensor (for the computer not the gauge).
Faulty map sensor or vac line.
Faulty throttle position switch.
The most likely cause is the injector drivers inside the ECU have gone short circuit and are holding the injectors wide open. This is easily checked. If you can get a reading with a volt meter across the two injector plug terminals with the ignition on, your ECU is faulty. The ECU controls the ground of the injectors, so if the injector wiring harness is shorted to ground, this too will hold the injectors wide open.

Maybe someone who works on GEOs will come by. I really don't know the car but I hear that Geo Metros use fuel injection and have a "fuel pressure regulator" that goes bad.
