Ok 1989 90hp v4. Remove all plugs, got it. Spark tester. Is it necessary? Also. How do you ground the plugs? Attach alligator clips to the end of the plugs and attach to the block? Also do you still connect the timing light over the sp wire? Back to the spark tester. If I do have to use it as I am pretty confident on the spark, I assume you connect one end to the sp and ground the other side to the block. Also how can you tell when your engine warms up as it seems that the water is too cold to allow the thermostats to open. Thanks for your responses!
