'93 Blazer was running fine and started hesitating like it was going to stall. Got it to the house and it wouldn't start about 11 hours later. Waited a bit and it started but wouldn't stay running. I have changed the plugs, wires, fuel filter, fuel pressure regulator, and spider. Fuel pump is about 5 months old. It starts fine but will not idle. I get surges when idling and it dies. No service engine light. None of these fixes has changed the issue so I don't think it is the timing. Any help would be appreciated. Going nuts over here. Thanks.

 

Forgot to include distributor and cap and rotor. Changed those out also.
