Car won't start.

[z31]

Sup guys I'm new to this site, I need some help I drive an 1987 Nissan 300zx. I just put another engine in after I blew the first one in less than a month. Anyway, I can't get the car to start it just goes ererererer, and no fire, only a backfire occasionally. I talked to Roy, and he told me to go to 300zxforum.com, but I can't seem to get it to work. Anyways I was just wandering if you have any ideas , I'm fresh out, I've tried all kinds of things.

Thanks
Tony Z31

check the timing!!

what he said.. timing is more than likely the issue. Either at the distributor (if no DIS) or the timing belt(s).
