Fuel pump problem in caprice LS 1990

(1990 Chevrolet Caprice)
in Clinton, IA on May 27, 2014
I have a caprice LS 1990. It takes 3 times start to run the engine. I check when I put the key in acc mode no gas comes to it's injectors but when I turn the key to start the car after 2 or 3 times of starting it run. I also check the pump connectors behind the rear bumper. When the key is in acc mode no voltage comes but when I start it come 12 volt. Please show me how can I fix it.

Pump is NOT supposed to run with key in the acc position!! ..... Even in the on position it only runs 2 seconds and then cuts off until enging is cranking or key is cycled off... on again!.... Have a mechanic test the fuel system pressure and run a scan test .... or cycle key 3 times, start it up and drive on...

Tanx, but when I put the key in on position the pump doesn't work even for 1 sec. And the pump wires doesn't show any voltage. After I start for 3 times and more gas comes to the back of injectors and before that there is no gas in fuel line from pump to injectors. I also test to put the key in on position 2 or 3 times before start the car but it doesn't help , as I notice no voltage comes to pump in on position.

I didn't get you, what do you mean? My English isn't very good and I don't understand what you mean. Please explain how can I fix it or which part should I change with new one.
