Just to clarify, the new timing chains that were loose didn't skip and weren't likely to skip for quite a while, I just didn't want to leave it loose. Check yours and let us know what you find when you get the chance.

If you are going to pull the plugs, do the fuel pump test when the plugs are out. Less strain on your starter and battery, and might clear things out if you somehow got a shot of gas in the engine. Remember to disconnect the power wire to the coil unless you also want to check for spark at the same time. If you're going to do that, hook up one spark plug to the coil wire and watch that while cranking (safety first though!). The sparks should be blueish white.
