Default 90' Bonneville SE warm starting issues

Hi, i've been having some starting issues with my Bonne. Just bought the car and was told it was the coolant temp. sensor... To start the car warm i have to use starting fluid. When it sits for a while it will usually kick over. So far i've replaced the coolant temp. sensor, fpr, and the thermostat(unrelated). Ive been searching around the forum to no avail, if anyone can point me in the right direction i would greatly appreciate it. Thanks, Zach Michener

Check the EGR. Also,m look over the ignition system With it running at night, spray a mist of water on the plug wires and coils. Do you see any blue flashing? Also test the coils. they may be going bad.
