The bolt was blue and chipped at the contact surface, where it was arcing like crazy, as I was trying to start it. Understand, the bolt was still there, just loose.
Agree 100%

If any main ground is off or loose, the engine will find smaller grounds through other systems. Like the ground on the back of the cylinder head...and use it to crank the car. It would be very slow to crank, and these little ground wires would become hot and likely melt.

Cam timing, ign timing, whatever the case, you said the car does not crank properly.

Thats where you start.

Connect the jumper cable red to the positive side of the battery.

Connect the black directly to the engine. This will bypass any poor ground between the neg batt terminal and the starter motor.

The car did run after the rebuilt.. the timming could of just jumped and stoped running. If timming is a tooth of it can still crank but just not turn on.. I will do that and put the red cable on the positive terminal and the black cable on the engine itself and see what happens... thanks for your help!!!

The chances of an s2k jumping time, esp with the chain setup it has, is near impossible.

ok so i tried bypassing the grounds.. i first connected the ground by the vtec selenoid and nothing, then from the block by a pulley and nothing, and then by the motor mount and nothing... same thing keeps happening.. it cranks twice then like the gauges lights kind of turn of and then back on and keeps cranking... it does exactly the same thing it would do if a battery would be dead but just keeps cranking...

I would pull the spark plugs out, and see if the engine turns over easily by hand. Just use a 3/4 or 19mm socket on the crank pulley bolt. A regualr 3/8 ratchet will be more than enough to turn it easily.

Find someone who is a good mechanic, get the repair manual and start troubleshooting the car. Don't know if you can reach the cable going to the starter, but if you can, use a multimeter, and read the voltage at the starter before you start the car, and while the starter is cranking over. Tip: voltage at starter should be the same as at the battery when not engaging the starter.. If it is lower, you probably have a bad ground/loose wire as others have mentioned..

Not to be harsh, but it sounds like you're clueless mechanically, and having bought a non-running car opens you up to alot of potential issues, certainly more than we can help you solve at this time. Hope you didn't get screwed, but time will tell.

Here's what I'd do right now:
#1. Check all fluid levels for level and contamination (coolant in oil, oil in coolant for ex.)
#2. Get car to crank normally. (see above).
#3. If the car starts, CHANGE oil and filter to good quality items.
#4. If car runs ok, go to church because you got lucky!!
#5. If car runs badly OR throws a CEL, stop the car and figure out what the code means and start working from there.

Didn't see Billman's comments before I wrote mine. He is THE MAN to listen on all this.

thanks for all your help guys.... so i decided to start really taking a look at it. I just wanted for it to be something simple but had to really look into it since i never found anything. So i checked the starter it was good, checked all the ground wires and they where pretty good, did a compression test and was great better than what i thought. I then did what Billman asked me to do and well i took of the spark plugs and started turning the engine over and saw that it wasnt turning freely... so to make it short i saw that they had redone the crackshaft and that the metals where standard size.. so hopefully ill have this thing running soon!!
