We replace our engine due of ccrankshaft damage so we get from of standby engine to install but sad to say say that we cannnot start the engine is only crank but fail to start up

Based on the information you have provided, there are a few possible reasons why there is no power on the crankshaft sensor plug and injectors:
Wiring issue: There could be a problem with the wiring between the crankshaft sensor and injectors and the ECU. Check for any loose connections, damaged or corroded wires, and make sure all connectors are properly seated.
Failed crankshaft sensor: A faulty crankshaft sensor can cause the engine to not start or run poorly. Check the sensor for any damage or wear, and replace it if necessary.
Failed injectors: If there is no power to the injectors, it could be due to a problem with the injectors themselves. Check the injectors for any clogs or damage, and replace them if necessary.
Failed fuel pump: A failed fuel pump can also cause a lack of power to the injectors. Check the fuel pump for any signs of wear or damage, and replace it if necessary.
Failed ECU: Although you have tested the ECU and found it to be in good working condition, there is still a possibility that it may be faulty. Consider having it retested or replaced if necessary.
It is also possible that there may be multiple issues at play here, so it's important to carefully diagnose and troubleshoot each potential cause until you can identify the root problem.
What engine size 2.0 / 2.4 /2.5L is installed? It may make a difference. All three use timing belts. These can break if not serviced at their correct periodicity. The 4-clyinder engines should be changed at no more than 90,000 miles and the 6-cylinder engine at 60,000 miles. All three engines are interference engines, which means that if the engine failed due to a timing break breakage, there will be internal damage to the engine since the pistons will hit the valves. This is why the belt must be replaced before failure. Of course, there are many other reasons why the engine could just shut down and not start, but depending on maintenance history, vehicle age, and mileage, this is what I usually check first.
You didn't mention the cap and rotor.
Are you getting battery voltage to the coil in the on and crank position? Are you getting a tach signal to the tachometer ?
Could be a problem with the engine computer among other things.
If your original blower burned up, or if the original resistor failed, it is likely that some of the wires leading to the resistor and blower BURNED slightly in the process, and will need to be replaced all the way back to where they connect to the fuse block. (The wires may have been pinched or otherwise damaged somewhere, so they no longer carry the amount of current required, causing the resistor to fail due to a low-voltage over-current condition.) Sadly a failed resistor can also burn the motor out. Check the windings of the motor (via the connector) using an ohmmeter to see if it is still good.
Hi Michael, Sorry to be the bearer of sad tidings but you have caused very serious problems to your vehicle. Every circuit which uses diodes and which were operational during your failed attempts at starting have probably been damaged. A diode is an electronic component something like a one way valve and can be compared with a water reticulation system. By connecting the battery the wrong way around the diode packs which convert AC current to DC in the alternator have been damaged. Likewise those in the computer, and any other electronic equipment which was turned on at the time of the failed attempts at starting will have been blown. The damaged components are not very expensive but to replace them will need a knowledge of electrical circuitry. If you have a friend you can call on to help you repair the damage, he or she will need to remove the alternator, computer, music system, climate control and any other systems which have failed and replace the electronic components damaged in those units. If you do not have a friend with that ability replacement of the affected units will be required. Sorry Michael Best of luck, John
Sadly the Kia Rio is an interference engine, this means probably at the very least you have suffered some valve damage. You may have also damaged the camsaft, pistons, and head. You won't really know until its taken apart.
The pneumatic suspension is very problematic and complicated on these model subaru's. One component fails ie; air shock, and damages another component ie; the pump. The pump is usually damaged by an air shock failure. The cost is more than the car is worth due to it's age and probably milage. when it comes to air suspension components (lots of rubber boots, seals, etc.) time is as important or more important than milage.. I hope this helps you in your decision. good luck!
