im getting spark from tha distributer and thru tha wires but #3 not firing. cant be tha injector cuz im gettin power only on one side of tha injector plug. wiring prob? has any one had this prob,i was also told that it could be tha ecu but very rare just put new plugs in and switched wires around hoping that was it but not my luck. no compression ruled out also cuz im not gettin power on both sides of injector plug some body tell me somethin good
