Really need a little more info. Not sure about what it does after it warms up. If it just dies Re check the coil and ignition module. If it boggs but doesn't stall then its starving for something. Fuel probably since you have replaced all that stuff already. Start with the fuel fikter. Best way is to put a fuel pressure gauge on it cold start it and watch if pressure drops when It starts acting up. I'M GOIN TO SAY FUEL FILTER. Final answer.

Looks like bad starter or starter solenoid

There is an oil pressure switch in parallel with fuel pump relay, if that switch is closed, the fuel pump will run all the time. Click on the link. At the fuel injectors, top wire is voltage, bottom wire is ground. If there is no ground, both wires will have voltage. Make sure battery has a full charge.

Dirty fuel filter! replace it with a new one. If that doesn't fix it, it may be the maf sensor.

A lot of the 1990 and newer cars have a fuel pump inside the gas tank. Others have it mounted on the left frame rail about mid car.

good place to start....injector may not be cycling...an injector tester would tell you for sure. If thats too much of an issue, maybe grab a new one from the parts store to eliminate it for the equation...

run the fault codes and check for cam/crank sensors. check operation of immobiliser. check fob key battery
check for ING fuse or fusible link near battery

Heater core on a corsica is tricky. It's under the dash in the middle. First disconnect hoses under the hood. Then remove plastic panel 8mm bolts under dash. Remove bolts holding the clips that hold the heater core in place. To remove the heater core you must peel back the carpet or you will not be able to get it out and a new one in. Once it's out, put new one in the opposite way. The carpet has to be peeled back and heater core manouvered to get it in and out. Good luck

Take off what you need to take off. I take off filters, mounts, and sensor to get some starters out. Some , you just have to wiggle around to get out. Make it easy for your self.

Here's a link to replacing your heater core,it's a job,be sure to replace your seals that the boxes connect to each other or air will go thru,your's is probably dry rotted.Also make sure your outlets are pointing in the same direction on both heater cores,if they are different,then your heater hoses going to them will be too short,happen to me. Use a 2x4 to hold dash up,I did.Repair Guides Heater Air Conditioning Heater Core AutoZone com
