rough idle hot start problem
 

I have a 86 fc n/a So far I have replaced all 4 injectors,alt,plugs,wires,trailing coil,o2 sensor.Grounded the boost sensor,main engine ground to firewall,secondary injector ground to firewall.,I also replace the transistor for the bac valve in my ecu.My problem is this the car will not start when hot.If I let the car sit for and hour it will start but I have to pump the gas peadle to keep it going? The car also will not idle to well for too long.If I let the car sit and idle it starts to sputter and after like 5 min it dies.I have the variable resistor set to full rich the car will not run at any other setting.The car will start after it has cooled to a certain temp.could my problem be a temp sensor? What abought the thermo wax could it become stuck? maybe a stuck FPR? I am at a loss for the cure

First thing I would do it check compression. That will narrow things down greatly.
