Did timing test with strobe light, spark and compression test just now.
Timing test results: strobe light with inductive clip on wire to spark plug on cylinder 1 showed 5 degrees retarded when cranking.
Spark plug test: First, all 4 spark plugs were wet with gasoline. While doing test I could not see a spark, maybe I did not ground the test spark plug properly, but I assume there is current going because otherwise strobe light would not light up?
Compression test: FI fuse and all spark plugs off, distributor unplugged. Results were as follows: 70, 165, 140, 150. Battery was getting kind of low by then due to all the cranking. Still cylinder one seems way out of spec. I did this test twice just to make sure, same results both times.
I hooked up the battery tender overnight. Next step, check timing belt? Also spark plug on cylinder 1 had a little bit of oil.
