98' K1500 with a vortec 305.
Truck runs really great. Except I am running into an issue where it's hard starting after it warms up.
It will eventually turn if i tap the throttle only while it's warm.
It fires right up in one turn when it's cold.
I thought it could have been the fuel pressure regulator but I just did a MPFI spider conversion (delphi) 2 months ago so that's all new. Also tried swapping out the engine temp sensor in the intake with a new delphi unit and it still does it.
The distributor and cap is new and was properly adjusted with a scanner tool.
Sparkplugs and wires have 5000 miles on them.
Could it be an issue with the fuel pump itself?
