97 5.7L Wont Start

I have a 97 chevy Silverado 350 5.7L and it started to stall everytime you excelerated hard about a year ago so we replaced the fuel pump and filter. And it ran fine for a while. But just a month ago the truck stalled when we went across some train tracks, and wouldnt start, So we replaced the filter and pump again... still wouldnt start. We repaced the camshaft sensor and still wont start but we have good pressure coming from the pump. We tested it. The engine will start if we put starter fluid or a little gas in the intake, but shuts off. We tried to start it for a while and it did not flood meaning theres no fuel getting to the engine and the spark is good.....What should i do?

Needs a distribitor cap,water will get inside and corrode the inside and it will cause that

the distributar cap was replaced this past summer and we have good spark
