    Changed out the timing chain bc I thought that was the problem, also changed the cam position sensor and crank position sensor, when turning over it spits & backfires through the throttle body, no check engine lights on and isnt showing any codes on my scanner, it's getting fire and fuel, won't even start with starting fluid... Any help would be much appreciated, thanks guys!

    Check the distributor and gear. In some cases it can grind down/break/crack etc... and skip a tooth. Had similar issue

    I wished it were that simple, it doesn't have a distributor, all coil packs on each plug... Just replaced the crank position sensor with another new one just in case it was faulty, still nothing
