Question about Cars & Trucks
You did not post the year make and model so it is hard to say anything other then go get an OBD reader from an auto store and use it. A flashing check engine light is serious and if you drive that vehicle, you risk engine damage.

Sounds like the fuel pressure regulator is going bad...this will cause the fuel pressure to be high and create a flooding condition. Which in turn will gas wash the motor and contaminate the O2 sensor with excessive fuel. Check fuel pressure with a gauge at the valve you are using to relieve pressure. You can find pressure specs on-line for that particular vechicle. If pressure is high...replace regulator, O2, change oil and reset computer by disconnecting battery for ten minutes...

Hi. the fuel pressure sensor is part of the fuel pump assembly. You will have to remove the fuel pump to replace this. I would go ahead and replace the fuel pump while you are there.You will have to Pull the strainer off the fuel pump and discard it. remove the
retaining clip for the fuel pressure regulator so that you can remove
the fuel pressure regulator. Disconnect the electrical connections for
the fuel pumps and the fuel level sensor. Remove the retaining clip for
the fuel level sensor and remove the fuel level sensor by squeezing the
locking tangs. the sensor is incorporated in this area.
Please rate and god bless.

you might try unhooking the battiey for 20min both + and - posties cuz that will force the computor to have to resest only if you have addressied the fuel pressure problem which taht would most likly be your filter which isn't all that much
