iv'e got a 1990 mazda miata that won't start. I painted the valve cover not to long ago and ever since I put I back on my car won't start, also ever since then when I put the key in the ingnition it sounds like theirs air coming somewhere out of my motor or somewhere else.

Check vacuum hoses for leaks.
