Trying to change the plugs for a 1998 GS300 but my owners manual doesn't give me any info regarding the number of plugs needed or their precise locations. Here's my main problem. I can't get the car to turn over. Checked all fuses and it seems this is a spark plug issue. I have replaced two plugs but problem still exists. I'm guessing there are more plugs but I don't have a clue where to look. Any ideas?
