Hi there - first task is to check for any problem codes. Your truck has OBD I diagnostics which, although not as precise as OBD II, can still be pretty helpful. Your poor cold start running may be due to a coolant temperature sensor problem, air leak in the intake, or idle air control malfunction. The catalytic converter will affect running after the engine starts to spin up more so than at an idle. Your other various fluid leaks need attention, but don’t necessarily affect the poor starting behavior your describe. I recommend a engine stalling inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.
