Cant get a 95 chevy 350 tbi timed rigjt

The ECM is resetting it,line the marks up on cam and crank or top dead center on firing stroke,and crank on mark,then unplug your distributor harness,and undo battery,turn the crank by hand 360 degree,s and check your marks again,then make sure distributor is on the number one plug,then reconnect the distributor harness then the battery,this should reset the ECM.

there should be a tan wire with a black strip somewhere in the harness that has a one wire connector that is your timing bypass and needs to be disconnected when setting base timing on your k motor, the connector is either on the firewall in the harness on the passenger side under the hood or it maybe behind the glove box by the ecm also check the harness from the ecm that goes down by the carpet
