[COLOR="Blue"]I installed the new start relay and still no start. I did a resistance check on the timer. I read online I should get a resistance reading of 2K-3K Ohms at the main terminals with the timer in the run/normal position. I had 0 resistance. So I guess the timer is shot?[/COLOR]
If by the "main terminals" you are referring to the motor winding then you may have just measured it wrong. Since the timer motor runs and advances the timer motor is OK.
On how to measure:
Disconnect one wire going to the motor and measure across it.
Use the meter scale just higher than what you expect to see, in this case the 20K scale (20,000 ohms).
If the scale is too high it would show 0 ohms.
If the scale is too low it would show infinite ohms.
[COLOR="Blue"]If I plug the dryer in and reconnect the wires I hear the timer running and the timer advances but I guess this doesn't mean much. Correct?[/COLOR]
No it does mean that the motor is OK.
In any case a bad motor is not relevant to your problem.
It is the timer contacts that are important.
Even with a blown timer motor if you manually set the timer to a run mode the machine should start up. It just would not advance the timer.
I did some searching and was able to find the following, it at least gives the wiring for the motor.

Has this been checked ???[/COLOR]
Using the wiring diagram as a guide.
Unplug the machine.
Set the timer at mid point of a timed dry cycle.
Unplug the wire at BK then measure the BK/BU timer contacts.
Use a low scale (200 ohms).
It should be 0 ohms.
If OK replace the wire.
Unplug the wire to either T or W (timer switch 4) and measure the T/W timer contacts.
They also should be 0 ohms.
If OK reconnect the wire.
If both the above measure OK then the timer contacts are probably OK.
The following gets a little more complicated as we have to remove the start relay's coil from the circuit to get accurate readings.
It must be taken out of circuit because it is wired in parallel with the motor so if left in you will read the relay coil resistance.
Disconnect the pink/black wire from the start switch.
Then one meter lead is attached to this wire the other meter lead goes on a blue wire at the start switch.
And measure this at your most sensitive meter scale,
Should be 1 or 2 ohms, theses are the motor windings.
Note: That you may have 2 blue wires at the start relay one will read all the time, the other just when the start is pushed.
Basically here is the circuit path you are checking.
PINK/Black wire : Tan wire : TIMER SWITCH 4, T/W timer contacts : WHITE wire : motor's START and RUN windings : thermal fuse : BLUE wire
Hope I explained this clearly and that it helps.
