You'll want to make sure your fuel pressure is good and the fuel filter (if equipped) isn't plugged. If flow is restricted, you might be fine around town but the float bowl may drain under freeway conditions

I'm not sure if your truck has a cap and rotor, but checking inside the cap for arcing, corrosion, and carbon tracks is a good idea.

That is where I'd start, hope this helps

This truck has a replaceable cap and rotor on the distributor and its very easy to change
