The ECM sends a GND signal to the Fuel Pump relay to switch it ON. When 'jumping' relays, there is a risk that you might feed +12V to Gnd switch line, in this case the ECM line. If left too long, this would blow the diodes in the ECM. Try using another ECM. Try following the ignition circuit from the ignition coil back to the ECM. One of the wires connected to coil should have +12v when IGN on. Sparking only happens when ECM sends GND pulses to the coil. If ECM is OK, check camshaft position sensor, which is also usually referred to by the ECM for ignition firing.

No switch just EFI relay to supply power to ECM. If your ECM seems like it's not activating other system like fuel pump relay, ignition coil,etc.etc. check that your immobilizer has been disabled. Some immobilizers will disable the ECU totally. Newer models have RFID type keys that needs programming if damaged. Best to scan your car and get the error codes before replacing anything.

Here is the definition for the code.
Test procedures are a little different depending on the make and model.

P0232 Description The Engine Control Module (ECM) provides ignition positive voltage to the coil side of the fuel pump relay. When the ignition switch is first turned ON, the ECM energizes the fuel pump relay, which applies power to the fuel pump. The ECM enables the fuel pump relay as long as the engine is cranking or running, and crankshaft reference pulses are received. If no crankshaft reference pulses are received, the ECM de-energizes the fuel pump relay after 2 seconds. The ECM monitors the voltage on the fuel pump relay control circuit.

The fuel pump and coil are on two different circuits.
The fuel pump is on the 20amp ECM fuse and the coil, ignition module, and injectors are on a 20amp fuse #10. But the ECM fuse could keep the coil and injectors from working.
You would need to test the fuses in the box in the engine compartment, and the fuel pump relay and coil for voltage and ground. The pump relay is grounded by the computer for 3 seconds when the engine is cranked.

You can buy a coil tested from advanced auto for 10 dollars to identify the spark. Have you checked compression?

Dear Sir,
As you saying you have replaced ignition coil and crank sensor, next is check relay fro ignition system in fuse box replace relay with other one for testing purpose only, if no change then next,if you can check continuity of all wire form Engine Control Unit to Ignition coil, if all wire are ok then replace Engine Control Unit (ECM) if any wire found no contunity please reconnect same wire or repair wire it will solve problem if not then you have to replace ECM. thanks.

you gotta ask the dealer im sure they will tell you over the phone it shouldnt be too complicated

check fuel pressure

fuel mix is too rich,check temperature sender.thermocontact,
