360 will not start, any suggestions?

Go back to the beginning, start with basics: pull drivers side valve cover, rotate engine around to #1TDC, pull distributer to make sure oil pump drive is correctly positioned; slot should point towards front bolt intake manifold, drivers side; if not, use large flat bladed screw driver to rotate drive around till it does, move it only one tooth at a time. Stab the distributer in, lightly snug clamp, use a multi-meter set on continiuty, move distributer till just changes, snug clamp a little more, plug dist. back into harness. Put the cap on (don't forget rotor), #1 lines up with rotor, firing order is 1,8,4,3,6,5,7,2, clock wise. Odd numbers drivers side, 1,3,5,7; even, passenger side 2,4,6,8

Things to think about: is the damper any good, has the outer ring slipped; rock the crank back and forth, watch the rotor, how much does the crank move before the rotor, timing chain shot?

I know this is like remedial, DUH stuff. I've had similar problems, and they seem to straighten themselve's out if you start from the beginning ...........

Good luck!
