you welcome

is the red security light flashing or steady on while you try to start it .

did you get also the key of the junkyard donor car or you are using same key that came with your car ?

have you inspected the connectors for all these parts for broken pins, flood damage cars ,the corrosion eats away from pins and they break off or make poor contact ?

do you have diagnostic scanner that you can read all the Subaru modules , not a small code reader that want do since they only read engine codes and maybe abs depends which one ?

Please let me know

Thank You

how high did the water get in the car , you can tell by the water ***** *****ne

check fuel pressure ,check throttle body connector , is it moving from 0 to 5 volts when you press on gas pedal ?

FUEL PUMP Shutoff discharge pressure.....370 - 677 kPa (3.77 - 6.9 kg/sq.cm, 53.6 - 98 psi) Discharge rate.......................105 l (27.7 US gal, 23.1 Imp gal)/h or more. ........................................[300 kPa, 12 V (3.06 kg/sq.cm, 43.5 psi)]

if you cant get to the ecu with that obd2 reader , you have to start there really, could be a bad ecu ,you have to able to communicate with it .

with both ecu non of them reading
Subaru Mechanic: Chad Farhat, ASE Certified Technician A6 - Electrical / Electronic systems A7 Heating / Air conditioning systems replied 1 year ago

sorry man , i have dealt with flood cars before , sometime you can get lucky , sometime you will spend weeks and dont get now where, the diagnostic logic doesn't not apply to it for a regular vehicle .like i said , you have to be able to communicate with it , if you think it is not bad then wiring to it has to be .

if this car dont equip immobilizer what kind of sercurity it provide
Subaru Mechanic: Chad Farhat, ASE Certified Technician A6 - Electrical / Electronic systems A7 Heating / Air conditioning systems replied 1 year ago

none if you say it does not have one ,it should be an unchipped key and no immobilizer module in the car , it should start right up, when dealer says turn key 3 4 times , ask him what is he trying to accomplish when he told you to do that.

did you supply him with vin # to check what your car is equipped with , how did he know you dont have one ,something dont add up here .

Ask Your Own Subaru Question
Customer reply replied 1 year ago
i gave them vin # and he said no chip key but maybe sercurity from keyless lock it
Subaru Mechanic: Chad Farhat, ASE Certified Technician A6 - Electrical / Electronic systems A7 Heating / Air conditioning systems replied 1 year ago

if you had everything disconnected , means it lost it throttle memory , if you cant communicate with ecu means the throttle cant send any info to ecu neither so if it cranks up and you press gas pedal and it falls on its face or dies then we go back to why the ecu cant be read that is one possibility and could be several more

Subaru Mechanic: Chad Farhat, ASE Certified Technician A6 - Electrical / Electronic systems A7 Heating / Air conditioning systems replied 1 year ago

i m& not aware of key less lock security only , you obviously are able to start it ,so starter works, usually most security in cars will kill starter, injector pulse & or ground to ignition coils

but since car is starting and running that tells me we have them, so i dont know what dealer talking about , on that issue a key less security !
