Default 1990 g series floods out

I have a 1990 g series van. I have replaced the plugs and plug wires. THe van will start up without even turning over one time. Purs like a kitten for about 5 minutes then it will rev up real high. If you touch the throttle it floods outs and will not crank. It has to be sensor of some sort mass air flow sensor or throttle position sensor. Any ideas? thanks Jeremy
