[DisEpyon]

i have another sr starting up swap question for someone that knows, and searching didnt do jack sheeit for me. yesterday i tryed starting up my car for the first time, i primed the oil first, then after that when i tryed starting it up it would crank and try and fire up. so then i looked and i had no fuel pressure reading from my guage.. well my fuel hoses were backwards, so i switched it, then the next morning start it up and it did but only stay on for about 5to8 sec. so then i thought i should pull the valve cover off and retime all the tick marks for the crank pulley and the chain to the cams and the cas. just incase, so i did, then i tryed starting it up and this time all it does is crank over and not even try to fire. thats were im at now. i thought it was spark plugs not gettting any spark, so i bought new ones, and same thing, so i check for spark and i do have spark. ive heard that after timing it the way i did the ecu is set to a different mode. so then i might have to change it. but i dont know how to tell when twisting the nob and what the red light blinks for on a mode. i checked all my wires and everything is good, ill double check it just incase again. please help me , im freaking desperate to drive this dame thing.
thanks, brent
