There is no re seting for the ecu.

What issue do you have that you had to reset the timing?

Even if it is in wrong, you should have spark.

Make sure your connections are good.

Check for voltage of 12 on the positive side of the coil. The negative side should pulse while the engine is cranking.

If a battery is low will that stop you from getting spark?

Yes it will. The voltage has to be lower than 11.2 volts.
