Hi I jus finished putting the radiator and spark plug wires back in my 79 244DL(B21F) and now it cranks but wont start. I have new sparkplugs and a new distributor cap, the spark plugs were pregapped for my car, and the r gettin no spark nor are my wires, and my rotor is also new. Could it be my coil or could my wires be connected wrong. Or what is the problem. Also I am buildin a new exaust system and i wanted to go for 2.25 or 2.50 which would be better and would i need a new exaust manifold and what kinda catalytic converter should i use.
