Good afternoon all,

I had a broken timing belt on my 1995 MX-6 V6 which I repaired as well as replaced the water pump. After putting everything back together, I filled with new fluids and new spark plugs and the car started and sounded normal. (I ran it for 2-3 mins a few times)

My next step was to remove each spark plug one at a time and check the compression which was decent at ~175. The engine started with the remaining 5 sparkplugs for each test except the last two cylinders, and only let the engine run for a couple seconds to get an accurate compression reading.

After testing and replacing the final spark plug the engine would crank, but not start. I was getting gas, but no spark when I tested the plugs. Any ideas where I should start to diagnosis?

 

How about the battery? Could have died from the cranking with no charging.

 

I'm sorry I worded my earlier message poorly.
The engine does crank and I charged the battery to 100%, but it doesn't start. I also had a friend try to start the car while I held a screwdriver to a plug but didn't see a spark.
The crank angle sensor wire connector was a little loose but like I said the car started 5-6 times without hesitation then didn't start at all so don't think it went bad all of a sudden. Also would a bad crank angle sensor cause no spark? I bought a cheap odb2 diagnostic tool with an adapter for an old 95 Mazda but it will not power up and was hoping someone here might have an idea how I might troubleshoot this problem.
