Hi I was reading an older post for high compression issue with your comments, but my car have some differences.

I have 1 Impreza 2008 automatic, without turbo 2.5, this is the car of my daughter.

Before the fail 1 fan#1 start to keep on, all the time

Fan #2 never turn on, inclusive when the a/c is turned on

The boyfriend of my daughter had the idea of connect directly the fan#2, using 1 cable from sub fan relay #2 fan to failing fan #2

1 day after this, the engine don't start.

Then my simple OBDII send me errors P0038,P0301 & P0303, and the unique way to keep on the engine was accelerating the machine with the pedal

I've verified the belt time was old and the belt time jump some dents.

I've replaced the bearings and the time belt.

Ive replaced the sub fan relay #2 

Verified the voltages from ECM to injectors and are ok according manuals

Changed crankshaft and camshaft sensors, and the issue still

Changed the 2 oxygen sensors frontal central and left bottom sensor, issue still

After change the time belt ,and adjust the marks of time ,the engine turn on without accelerate the pedal, normal turn on, but shaking and rough idling

The actual symptoms are:

1)Injector 1 & 3 are not receiving pulse was verified using a simple bulb light (auto zone is selling this bulb),injector 2&4 are working ok with the bulb

2)Turning the key to on position the fan #1 keep all the time on

3)I've verified the compression with the engine warmed to normal temperature: 240,235,230,230

4)Rough idle and shaking when the machine is turned on, is worst when the machine reaches normal temperature

5)Removing injector connector 1 & 3 not affect the shaking condition

6)Removing injector connector 2 & 4 the machine fail and turned off

Please give me some recommendation, this error is rare for me.

Regards
