1990 Dodge Caravan • 160,000 miles

My caravan 2.5 none turb. The engine starts normal when I turn the key, then stops. If I pump the gas paddle fast it run a few seconds. I have replaced fuel pump, presser regulater, injector, engine shout down relay, engine computer, fuel filter. I check the electric at the injector, I have no electric with the key just turn on. Should there be electric then. And if so what can I look for, I am lose. And broke. Hope you can help. Thinks
