Engine wont start

[JDM_240sx_2nr]

Yes I own a 1990 Nissan 240sx hatch back and i just recently rebuilt the ka24e single overhead cam that was in it. I replaced everything on the motor including new larger cams and a stainless steele header. Now that I have goten it put back together it wont start!!!!!!!!!!!!!!!!!!!!! Ive replaced the distibutor, spark plugs and wires and tried a new computer and it still wont turn over!!!!!!!!!! I was wondering if any 240 owners could help me out with this prob and maybe start in the right direction to getn my car back on the road!!!! Please!!!!!!

Thank YouOrlando

I don't suppose you know much about engines? Sounds like you've done a lot of work to it though. We can't help you because we know nothing of the actual problem, other than "it won't start." With that kind of description, my diagnosis would start with something like "have you tried turning the key?"

All jokes aside, try to fill out the following:

Does it have spark? And, where/how did you check for spark

Does it have fuel pressure present at the rail when the ignition is on?

How sure are you the cams are installed correctly?

Do you have battery power at the starter?

Does it turn over, but not start, or not even turn over?

Any fuses blown/not installed?

Battery cables properly connected, power AND ground side?

More to come later, after you finish those.
