have you got the timing set correct ,and did you fit the timing belt with all the timing marks lined up ,etc , if there correct ,check for spark ,by pulling off a spark plug lead and fitting an old plug into the lead ,then crank the motor ,dont hold the plug with your hand ,use insulted pliers ,if you have spark, ,if no spark check coil wiring ,coil, crank angle sensor,
have a tech pull the codes from the computer, misfire code can be system or component generated ,however if the misfire is only a specify cylinder i t may be narrow down to sticking,clog,fautly injector or circuit,spark plug or wire shorted coil and or ciruit also fuel and compression ,further information needed code are codes perform power balance and relative compression test
firing order is 1 8 4 3 6 5 7 2 remove number one spark plug its always the right drivers side head..closest to the radiator turn engine crankshaft till the top of number one piston is all the way to the top or if you have help put your thumb over the plug hole sand have someone bump the engine over till the pressure in the cylinder pops your thumb free,,,check front of crank harmonic balancer for timing mark if you need to move crank by hand till the mark lines up to the 0...or top dead center....then make sure distributer cap is pointing to number one plug wire if not remove dist and turn to the right position and install...if it dosnt go in all the way dont worry hold light down pressure on it and just bump the engine over and it will drop right in place then recheck your settings and install spark plug start engine and adjust with timing light check your specs
