ck fuse sti dont work run new hot wire to it make sure wire is hot wen key is on and no power wen key is off cut old wire so you dont get feed back in your wireing

THE CHECK ENGINE LIGHT COMES ON TO INDICATE THAT A FAULT HAS OCCURRED IN THE ELECTRONIC ENGINE OR EMISSION CONTROL SYSTEM, WHEN THIS LIGHT COMES ON A FAULT CODE IS RECORDED IN THE MEEMORY OF THE COMPUTER, YOU NEED TO HAVE THE COMPUTER SCANNED TO FIND OUT WHAT THIS FAULT CODE IS DO PROPER DIAGNOSIS AND TESTING CAN BE DONE TO CORRECT THE PROBLEM, COMMON FAULTS ARE DEFECTIVE O2 SENSORS ON THIS MODEL.

i have the same car and i had the exact same fault and it was the crank angle sensor,get it checked for resistance i think it should be 1000 ohms and mine was 3000,once replaced it has never happened again.Even my friend who dynos them was surprised but that was 100% it

1. Locate the EFI main relay in the upper left side of the dash. Check the two Red wires for battery voltage with the key on. Check the Light Green wire for battery voltage from the computer key on.

2. At the computer check terminal 79 for battery voltage key on. Terminal 79 is a Yellow wire.

3. Check all power and ground inputs to the computer.

4. If the power and ground inputs are good at the computer check for a shorted 5 volt reference at the throttle position sensor and the boost sensor. A shorted 5 volt reference can cause no start, no spark with no injector pulse. 1. Check for the AC voltage waveform from the Crank sensor making it all the way to the PCM. On this Subaru, if it had a crank sensor signal, no cam sensor signal, you would see injector pulse, no spark. If it had cam sensor signal, no crank sensor signal, you would not see spark or injector pulse. Hope i helped if any more ?'s feel free to ask.....

Hi,
Fault codes as follows
45 Pressure Sensor Duty Solenoid (Turbo Models)
42 Idle Switch or Circuit

Those are the correct codes for a Subaru.

good luck

Dan
