97 Dakota, 3.9 L. Starts fine from cold. After heating to normal temp, and turning off. Truck will not restart until it cools a while. Replaced plugs, wires, dist. cap, rotor, coil. No help. Fuel appears to be getting to injectors. Check engine light on, but had chance to check code yet. Anyone with similar issue?

 

Go out with a pen and paper and:
flip the key on-off-on-off-on (thats 3 cycles, it may take 4 or 5 cycles, i don't know. NOTE: ON does not mean START) and than look at the odometer. it should give you the codes.
Post them back.
