thanks bob. Did all that and hooked up to computer and the relay was telling it to crank but the ecu was not responding. And the only time It wont crank is when the ecu gets warm. After letting it cool down it will crank and start but then randomly shuts down. I bought the ecu witch had been tested at the junk yard. I didnt know if it had to be reprogrammed before i installed it or if it would mess anything up if i didnt

There has to be a pulsing crank sensor...you seem to be on the right track. Take it to a component level rather than stepping back from the automotive masterpiece.

is it...yes it is, a Crank Angle Sensor. Replace yours today!
