Hi, So here's my situation. I pulled my oil pump becuase the gasket was leaking. In order for things to work again now i have to get my #1 piston to TDC. But while trying to do this my rotor was not spinning on the distributor cap. I got it TDC and put the Rotor where i thought it belonged and put everything back together. It didn't start but sounded like it wanted to. I don't know what part of the step i did wrong. What do i look for on the distributor to know that it's in the right position in relation to TDC ???

Also, do i have to now take the oil pump back out to start the process all over ??

Any help would be greatly appreciated. Thank you.
