How much fuel pressure did you get when testing?

Customer: replied 1 year ago.
I get a solid 60 psi when cranking, just put a new pump in the tank Friday. It started after putting it all back together. Let it set until today now wont start
Customer: replied 1 year ago.
This truck has had some issues while driving, sometimes runs fine, other times will stumble until warm then it is okay. New wires, rotor, distributor cap, plugs, radiator, thermostat, alternator. Now fuel pump and filter.
Expert:  Dave Nova replied 1 year ago.

How long has it been since the cap and rotor have been replaced?

Customer: replied 1 year ago.
About 4 mos.
Expert:  Dave Nova replied 1 year ago.

These engines have a bad habit of building up moisture inside the distributor cap. Remove the cap and look for moisture or corrosion buildup. If you see any, go ahead and replace the cap and remove the screen in the base of the distributor housing. This will prevent future issues.

Okay I will try that. Was thinking it wasn't the fuel spider since it won't start at all.
Expert:  Dave Nova replied 1 year ago.

Let me know how it does. If you still get a no start but the engine will start on starting fluid, then I would suspect the fuel spider. Distributor cap is much easier problem to address first.
