no start after heads/cam/intake install help!!

finished installing etp heads, streetsweeper cam and ported fast intake and a coil pack relocation kit. i went to start it up today and it just cranks no start.
i have fuel, spark, and i checked all my fuses and sensors, they are all good. checked my ground straps behind the head, they are all good. still no start i'm stumped. when it cranks it backfires every so often and won't start. any ideas???

haven't checked the map sensor yet, but i don't think its bad. What are some of the characteristics of a bad map sensor?

ok, if you have fuel and spark, and you degreed the cam, it's safe to assume that the probelm is pobably with coil relocation. Whose kit did you use, how did you do the wiring?

i used cc performance kit and followed their directions, marked all the coils, put them back where they belong and to their corresponding cylinders. i checked them over and had a friend check them they seem to be ok

I think it might be the cam if it backfires every so often.

wont start after cam swap

Just got done with installing a thunder racing TR 230/224 .575/.563 111lsa cam started right up and after about 30 seconds began to hear valvetrain noise so i shut it down and found a messed up rocker. After replacing the rocker it wouldnt start so i pulled the plugs and they were drenched in fuel, i thought no fire, tested that its got fire, changed the plugs still same thing, checked the crank sensor and it was bad replaced it still wont start. If anyone has any idea what is wrong or it just needs a tune that bad please let me know
