1994 ford ranger 2.3 won't start in real cold ,good fire,gas,won't start even when using starting fluid,got any thing for me?

Water in fuel frozen in fuel lines? That's the most common reason.

Does it crank? If so, does it crank slowly?

There are many things that could cause this.

Ok.. good point... the OTHER most common problem is a worn out battery... since battery oputput goes down with the temprature.. you notice it more on a cold day.

Thoughts:

. Replace the Engine Coolant Temperature (ECT) Sensor, which affects fuel injector pulse width. The ECT Sensor is a temperature dependent resistor (thermistor), whose resistance decreases as the engine coolant temperature increases. It provides a richer mixture when cold, leaner mixture when hot. They become corroded, due to not changing the coolant frequently enough, flood the engine, and waste a tremendous amount of fuel.

. Replace the Ignition Control Module (ICM) and coil.

. Remove and fully charge the battery. Afterwards, check the condition of each cell (E-Z Red S101 Battery Hydrometer). Clean the battery terminals and cable connections; check the condition of the cables for hidden corrosion and breaks.

. Use SAE 5W-30 full synthetic engine oil.

Will it start with a jump start? If it does, replace battery AND replace negative and positive battery cables. A internally corroded battery cable will give all of your symptoms. If the battery is more than 4 years old. Replace it.
