i have a 87 crx 1st generation. the car is carbureted with a d15a motor. the motor was running fine before i desided to give it a good tume up and beef up. i just took the motor apart i replaced the head gasket, timing belt intake manifold gasket. the exhaust is different i have bought a hedman header it is not on the car yet. since i bought a header some of the emmisions stuff no longer was needed. the mechanical fuel pump has been replaced with a holley red pump. the car is all togther except for the exhaust. i crank the car over and it will not start i will not even try to start. it sounds like there is no compresion now it just does not sound right. i know everything is at top dead center and the rotor button is pointing at the number 1 posiotion so i am pretty sure that it is all lined up right.please help me i need it to run this is my favorite toy.
