water getting in electrics somewhere lights perhaps or water in the fuel from hole somewhere in tank

If your problem is pressure when you release the gas cap it could be one of several problems. The first two are easy. A fuel pressure sensor on top of the charcoal canister under the computer and air filter on thew drivers side engine compartment. The next is the purge valve located on the front top of the engine under the cover. A hard line runs from the purge valve to the sensor on the charcoal canister.

The third is the most difficult. It is the fuel tank pressure sensor on top of the fuel tank. I believe you will need to drop or at least lower the fuel tank. Not an easy task. I have heard some models have an access plate in the trunk under the mat but mine did not. All are under $50.00 ea. and readily available at your local parts store or online. It is very important you get this fixed asap as it will build enough pressure to find a weak spot in the tank and rupture it. That happened to me.

While it is not ideal, you can temporarily loosen the gas cap to where it is just sitting in the filler tube when driving until you can fix it. Then have your check engine light reset.

loosen gas cap if sucks air vent solenoid or gas cap. take gas line loose at motor cycle key to pump gas in glass jar. check for water

The problem is electrical. Check the dist. and timing chain

You don't need the code you need to read the code and cross reference it to a fault code list.
A code reader plugged in under dash will read the code and provide print out and the option to reset the codes..
The light is often triggered by a fouled air fuel mixture sensor or 02 sensor, also sometimes a loose gas cap or leaky exhaust near the catalytic converter

I had check engine light and TRAC OFF. OBD-II MIL code was P1133 which is Air Fuel Ratio Sensor Response Malfunction and scanned by AutoZone. After disconnecting the battery for 10-15 minutes, the lights went off. I cleaned the gas cap and tightened it firmly. For the last 400 miles, the lights have not come back. When scanning using Snap-on one, no code was detected. I think gas cap was the reason for the lights.

your mass air flow sensor right after the air filter needs to be cleaned i had the same problem
