Your problem is a leaking injector when the car is shut-off., that is why you need to hold the throttle to the floor to shut off any additional fuel since the engine is flooded. Your problem has nothing to do with a starter.
Starting issue when engine is warm...
My 5.0L 1990 LX starts fine when cold but will only start when warm when I put throttle to the floor. I have replaced O2 sensors, adjusted the TPS to be .98V dead-on, and cleaned the idle air control. Any other ideas from anyone?
Thanks!

The easy way is with a Fuel Pressure gauge. Start the car shut off and watch how fast the gauge drops. The other way is also easier, run the car warm shut off the car hold the throttle down pull the coil wire crank for a couple of turns and now pull the plugs. Look for the wet plug. You probably won't have any codes unless the MAF is bad which is causing the flooding issue.
