My subaru started smoking then cut out now the engine light is flashing continuosly?

Check code first,why you changed radiator?

Could be a faulty O2 sensor. The sensor would not take action until the engine warmed up. Have you checked for trouble codes in the engine computer ?

It could many things, please go for a scanner test

50-60 psi is not enough. you want 130+

This link will help with the security light. Read the whole page carefully. The info is good and depending on your year, there might be a solution for you. http://vatspasslockpasskeysecurityhelp.yolasite.com/

As far as the blue smoke, thats normally burning oil. You might have multiple problems. Id suggest reposting about the smoke. The link should help you with the security.

hi check the exaust for smoke if its smoking a white or a blue smoke it means the motor is worn, but i would try changing the ignitor or ecu 1st as they send the ignition pulse telling the cylinders to spark, if either is stuffed that could cause your problem

you have a severe missfire thats why the light is blinking
the smoke and sound were the cat converter[s] glowing red hot from the missfire
dont drive it untill the missfire is fixed or youll ruin the cats[if not already] plus a good chance of fire exists

could be plugged air filter causing engine to breathe through pcv valve thus making black smoke

could be transmission fault, connect the 2 loose black plugs together under the drivers side dash, turn on ignition, no start, the ecl will flash the code, slow flashes are 10's and fast ones are 1's. codes can be got from bba-reman.com

power light flashing means trans sowas he able to retrieve any codes?check harness connections for trans in engine compartment,also wiggle engine harness in area between tran and engine bad groundf loose connection sounds like cause
