Hi all. I have a 1993 Maxima and after I had changed the head (closest to the firewall) and aligned all the sprockets for the timing at TDC, the car will not fire up. I changed the dirtributor location to the number one terminal with cylinder #1 at TDC (per Haynes Manual) and still nothing. Everything is connected correctly, vaccuumm hoses, fuel and electrical hoses. I know there is a spark and fuel delivery. Please help!!!
