Crank no start

Replaced fuel pump, cps and coolant temperature sensor. The fuel filter was replaced few months before the fuel pump. Replaced direct ignition cassette with another one, still no start. I replaced the map sensor with a used one from scrap yard still no start. I have not checked the fuel pump relay yet or the computer or ecm. The red triangle with exclamation point is lit on dash. Check engine light is on, but it did not reveal any codes when checked. The fuel injection idle air control valve has blew 4/hoses already. Can that be the problem? Please help car has been sitting as a result.
