When warm sometimes it stalls and is hard to restart and when it starts up it is very weak, it has problems getting on step. It,s probably because of the weak spark. It has new plugs, ignition coil and fuel pump.I think it is the coil under flywheel or switchbox. Any idea how to test these parts!!!

Are you certain that the engine is getting fuel? If not, then you will have to verify that there isn't any blockage in the fuel system to prevent the fuel from reaching the engine. If fuel is reaching the engine, try the following
1. Check compression values for each cylinder.
2. Inspect electrical circuitry in the distributor assembly (slack wires, broken wires, dmaged rotor etc)
3. Check to see if the timing belt was not severed. This belt transmits the drive from the crankshaft to the camshaft. If the belt ius severed, the camshaft cannot rotate in order to open the valves

Sounds the EGR valve and EVP sen is bad even if you tested it. The EGR valve cntrols idle and if carbon up will make the car stall or idle high and low (rpms going up and down) This was common on all cars during that time. I would say replace the EGR valve and senosr. This should take care of the problem. One more thing have the fuel pressure check on the car.

Sounds like it has jumped timing, dont know which engine you have so could be chain or belt.
