1986 spider died while driving about 6 years ago. I tried starting it a few times but hadn't solved the problem. Now I have determined that the rev sensor was open and have replaced that. And freed up the stuck brake on the right rear wheel. Took the spark plugs out and I want to turn the engine over by hand a few times before I put in new plugs and battery and try to start it. Put a rubber strap wrench on the water pump end but it finally just slipped. I put the car on the ground, put it in fourth gear and tried to push it forward but no luck. I've put oil but not Marvell Mystery oil in the cylinders and changed the oil, which looked fine. Hoping I don't have to take the fan and radiator out, the only way to reach the nut on the crank pulley. Other ideas? I was thinking of getting a leak-down test adapter to use compressed air to pressurize the appropriate cylinder.
