You say it won't start... it's turns over, just no combustion?

To make an internal combustion engine start and run, you need 4 things.....

The trick is to remember "FAST".

F - Fuel.. Verify that you are getting fuel injected into the engine. The simplest way to do this is to take a propane torch, open the throttle plate, and feed a bunch of propane into the intake. Then try to start the motor. If it fires and dies, you have a fuel problem. If it doesn't continue down the list. If it does, come back here and tell us. We will help you troubleshoot the fuel injection.

A - Air..... Make sure there are no vacuum leaks on the system. Follow the vacuum diagram for your car (available from the bird board). Fix any misrouted or damaged vacuum lines.

S - Spark. Pull the coil wire from the distributor and lay it on the engine tin. Have your toolwench crank the engine over. If you see a nice blue spark jump from the coil wire to the engine tin, you have spark. If you don't, check the points and condenser. Otherwise check the cap and rotor. Also verify that the spark plugs aren't fouled out. I would suggest replacing the plugs on general principles.

T - Timing. Line up the timing marks on the fan with the mark on the fan housing. Then pull the distributor cap and make sure the rotor points at or very close to the thin little line in the distributor body. If the rotor points away from the mark, rotate the engine over again and realign the fan and housing marks. If it points anywhere else, the timing is off. Check to make sure the firing order is correct. Trace each plug wire back to the plugs, and make sure they are on the correct towers on the distributor cap.

That's the basics of troubleshooting a no start condition.
