1991 Ford Probe

I have a 1991 probe with a 3.0 6cyl. eng. The first start of the day it starts within one crank. After it warms up it has to crank and crank before it fires. Changed the following: plugs, wires, cap. rotor, module on distr. No codes in computer, ohmed sensors hot and cold all within book specs. Pump pressure checks within specs. Runs perfect otherwise. Uses only hi or mid range fuel. Has anyone seen this?

How about the MAP sensor or mass air flow if so equipped?

Have they been checked?
