What is your question?

bought this van under the impression the only thing wrong was the water pump and fuel pump. well i put both on and it cranked 3 times and when i put it in gear it cut off. then i was told to put a new neutral safety switch. i did that and it cranked about 6 times and even moved it around my yard.but when i cut it off and it got cool it wouldn't crank any more. please please help me
