Hi!

My car gives me that code. Is problem in electic systems or in fuel system? If its in fuel systems, what could be broken? I changed new relay and walbro 255lph pump recantly. Code occured before relay change, but it didnt disappear after change.

Could it be crank sensor or cam sensor?

Did you happen to unplug the battery during your work?

If not, disconnect the battery for about 15 minutes, then reconnect, start the car up and go for a bit of a drive. Now check to see if the code still exists.

Problem is that car doesnt start. Starter engine works fine, but it wont start. Car used to bog little with WOT. It got worse and start to bog every time when it goes boost. So far Ive changed spark plugs and wires, fuel pump and relay, fuel filter and that o2 sensor.
