well,im still getn nowhere.pulled all plugs and getting bright spark,plugs are wet from gas,this is the second set of plugs its gased up so its not a fuel starvation problem,or a spark problem.the timing is dead nuts #1 tdc on compression stroke,with the rotor sitn on the #6 stamp on distributer,crank timing marks dead on(both marks),and even pulled crank sensor and pickup tooth was right there where it should be.checked compression and they all 160-165.
seems to me like its a security lockout or something telling it not to run.i pulled the dash and the security light bulb spot didnt have a bulb in it,looked like it never has had one in it.the only other thing i saw in there was a small red light coming out of dash by light switch,folowed the wires back to a black box and a baterry.the 2 wires to bulb were cut.anyone figure this mess out before,??
