Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

In order for the engine to start and run you need proper fuel pressure, injector pulse , good spark to the spark plugs and good compression. If you can check each one of these thing and see which one you are lacking we can work from there to try and determine the cause . Post back with the results and we can work from there.

the car never had a problem until I put the wrong intake camshaft position sensor. I clean the idle control valve, all it does now is buzz when the car is in on position. the radiator fluid starts to automatically flowing as well

Have you gone back and rechecked all connections as well as grounds. Are you setting any fault codes now?

activation map cooling

Well at this point I am not sure how to advise you. I will open the post back up and see if someone else has something else to offer. If someone can help they will post back.

if the sensor sent the wrong signal to the ecu can the hardness wire be bad?
Expert:  gomi_otaku replied 1 year ago.

If the P1622 fault keeps coming up, even though the car is not running, I would suspect the engine coolant temp sensor in the thermostat housing. This could also be causing your issue with starting (it is cranking over without starting correct, not failing to even crank over?) as the default failure for most ECTs will set your coolant temp very cold, effectively causing your ECM to flood the intake with fuel. Try holding the gas pedal to the floor to open the throttle, and crank for a while to see if it stumbles and starts.
