Did you check the spark plugs???

You really should get yourself a Haynes repair manual (if you don't already have one). You might find it available at your local library. Here's a link to one from Amazon.com (they are also sold in most automotive stores). They are extremely helpful for any repairs.

+1, if you don't have spark the first place you should check is the plugs themselves.

what happens if the TDC sensor fails ?
