SR will not start

[sil_8t]

Well i had it running for about a week or so, but when i would get on it there was a loud noise under the valve cover(timing chain). After replacing the chain and guides and my tensioner, i havent been able to start it. I got fuel i got spark, still a no go. when i put on my chain it was all accurate with the marks on the cam gears and that lower gear. and i made sure it was at TDC. i also stabbed the CAS right, being that it was my 4th time doing it, and it worked before the chain replacement. heres the list of whats it doing.
-backfiring through the intake
-oozing a thick black smoke from the fart can
-backfiring a little (exhaust)
-wetting the hell outta my plugs(new plugs)
-turning over then itll stop then turnover again (never letting off of the key
-if you hook up a timing gun it didnt flash(but it does spark,might be the gun)
-if you give it some gas while trying to start it will back fire a little out the can.
please help
