1985 Ford Mustang will not start

Set engine to TDC on the compression stroke on the first cylinder, pull your distributor, set rotor to 1 cyl.

Back of 10*(retard the timing 10 degrees), then try to crank, if it does not start check the spark on the plugs, there are a few ways to do this, just get a spark tester.

If there is spark its a fuel problem.

Check your fuel pressure, if it is a carbed engine, try to use starting fluid, if it does not sputter, or try to turn over, then its most likely the carb itself and/or a spark issue.

If it sputters a little, or trys to start and dies, then you most likely have a fuel pump out, or a clogged fuel filter.

Pray its the fuel filter, fuel pumps are a pain to get too, due to the need to drop the fuel tank.

Check your compression now, if you have a compression tester, anything over 100lbs is more than adequate.
