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

update: checked the cam today and it was installed correctly, cam and crank sensors are good, also i made sure the coil pak relocation kit was installed correctly-it was. valves are not too tight cuz i checked it with a compression tester today.....so i believe its the old tune that is causing a no start... unless anybody has any other ideas????

at first it sounded like you messed up the coil relo, but if you marked them and hooked the connector to the right set, then my next thoughts would be your timing internally......did you set it perfect and roatate the engine a couple revo's and see if it was on....? I would think it would fire if it was a heads and cam swap and everything was done right......without a tune.. if it diddnt just start then it seems like no fuel or spark....
But backfiring sounds like incorrect timing imo.

my problem was i put the #7 coil on the #1 cylinder, and it would backfire like hell cuz the firing order was wrong..try flipping the coils vise versa..

today i noticed that the coils on the passenger side are reversed as in the one that was on the #8 cylinder is now on #2 and so on but i don't think that is the problem cuz its just the coils themselves. After they have the plug on they still go to the right cylinder ex:first coil goes to the first cylinder and so on???? or am i wrong.....

i read about this all the time, thats what i said . coil relocations then cars dont start...make sure you got them right...a coil is a coil and interchangable but the plugs and the firing order is what you need right...

most likley it is..you want to hurry and drive/hear your new cam..and you start it and it dosen't idle, backfires..you think you fucked something up..then you look at the numbers on the coil..and realize its on backwards..

do things right and you most likely can hear drive your new cam quicker....now the poeple that F'd up are doing rework to drive/hear their cam and they have no idea what is wrong with it!!! 
i hope they can drive/hear it soon but most likely it is caused by themselves...maitenance induce maitenance..imo

ya i hear that, nothing worse than a unexpected hiccup during a swap or install of something....seems like whenever I do anything I always end up still going to autozone in the middle of it for something lol

well it wasn't the coils the question that i had was i know the coils are not side specific but are they cylinder specific when they are mounted on the stock rail?

hope this works cuz i'm pulling my hair out on what this problem could be
i spent about 5 months on this install making sure everything is ok, i was so meticulous with everything i installed. This was the first time i have done an install slowly, and the first time i ever had a problem starting a car.....go figure
