When my 88 is cold it starts right up with no problem.. When it is warmed up, it cranks and cranks and I have to pump the gas to get it to start. Usually takes about 5 sec. This is not right.. Any help appreciated.. Thank you

Leaky injectors can cause a hard start when warm. Don't pump the pedal. Holding it down starts a "clear flood" in the ECM.

When mine did this, I ended up replacing the injectors. Put a fule pressure gauge on and see if the pressure bleeds down right after shutting the car off. If the pressure starts dropping right away fuel is probably leaking through one of more faulty injectors resulting in flooded engine condition.
