Fuel leaking at tank when motor is running, stops when engine is off 1992 Honda Accord

P1457 HONDA - Evaporative Emissions Control System Leakage EVAP Canister Systemhttp://engine-codes.com/p1457_honda.htmlForum CodePossible causes- Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap There is a Honda factory service bulletin with information on how to diagnose the P1456 on the following Honda models:
1998 Honda Accord
1999 Honda Accord
2000 Honda Accord
1998-2000 Honda Accord
symptoms- Engine Light ON (or Service Engine Soon Warning Light)
- Possible a noticeable fuel odor caused by the release of fuel vaporsP1457 HONDA Description The evaporative emission (EVAP) control system stores fuel vapor from the fuel tank in the EVAP canister temporarily to prevent it from escaping to the atmosphere and to enable it to be drawn into the engine by intake manifold vacuum and burned. In addition, the onboard refueling vapor recovery system (ORVR) stores fuel vapor generated when refueling in the EVAP canister.

The EVAP control system leak detection method improves the accuracy and frequency of the detection by determining faulty components and vapor leakage for each part. The EVAP control system (from the purge valve to the fuel tank) is divided into two parts. One is the "EVAP Canister Side" (from the EVAP two way valve to the purge valve) and the other is the "Tank Side" (from the EVAP two way valve to the fuel tank). There is 0.04 inch leak detection and 0.02 inch leak detection. If the 0.04 inch leak detection results are OK, the 0.02 inch leak detection runs. The P1457 code is detected when the EVAP system has a very small leak.

P0107 HONDA - Manifold Absolute Pressure Sensor Circuit Low Voltagehttp://engine-codes.com/p0107_honda.htmlForum CodePossible causes- Manifold Absolute Pressure harness is open or shorted
- Manifold Absolute Pressure sensor poor electrical circuit connector
- Faulty Manifold Absolute Pressure sensor
- Faulty Engine Control Module (ECM) When is the code detected?An excessively low voltage from the sensor is sent to ECMSymptoms- Engine Light ON (or Service Engine Soon Warning Light)
- Engine rough idle
- Engine hesitation
P0107 HONDA Description The Manifold Absolute Pressure sensor provides instantaneous manifold pressure information to the engine's Engine Control Module. The data is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel metering for optimum combustion. A fuel-injected engine may alternately use a Mass Air Flow sensor to detect the intake airflow. A typical configuration employs one or the other, but seldom both.


In some vehicles the absolute pressure sensor is built into ECM.

There are many areas of concern for a fuel leak. The fuel tank is constructed of a rigid plastic and is fairly unlikely to leak. The fuel pump is housed inside the tank and transfer gasoline through a combination of metal and rubber lines to a filter in the engine compartment. From the filter it enters the fuel rail on the engine. Any unused fuel then navigates through metal and rubber hose back to the tank. There is also an opening in the tank for the fuel filler.

The first thing to do is establish a general area of the leak. Is it at the rear of the car? Front? Middle?

Secondly, does it leak at all times or only when running? A leak that worses when the vehicle is running would indicate the pressure or return lines from the fuel pump are at fault.

Begin by determining the general area and depending on your ambition and tool resources, raise the car and inspect closer. Be sure to be safe and use a jack stand. On older hondas the leak is typically a corroded metal fuel line or brittle rubber line.

Fuel starvation. How well do you trust your fuel gauge?
Also check you gas tank for damage, dent or otherwise.
Possible at speed fuel shifts towards fuel pump and away
when stopped.

Could be a weak fuel pump with the strainer being dirty, the fuel filter could need changed or possibly a leak in the seam of the gas tank. Pay attention to see if it also happens when you make a hard accelerated left turn, or if it is less noticeable when your fuel tank is full. When your tank is full, look for leaks under the car. You should also check for leaks in the fuel line leading from the tank all the way up to the fuel filter. You might get a CHECK ENGINE LIGHT that refers you to the injectors. This most likely means they are thirsty for fuel and are not getting it in the regular amount. Good luck.

You'll need to remove the fuel tank and unbolt the pump from the fuel tank.

When you turn the key to start, the engine cranks over? You must check for spark and fuel, if one is missing, the car won't run. Pull a spark plug, with plug wire connected and plug on a metal surface of the engine, have someone turn the key to start, while you watch for spark at the plug. It is easiest to see spark with car out of direct or bright light. If you have spark, attempt to start several times, pull a spark plug and check for evidence of fuel (wet) on plug. Let me know what you find, we can then continue.

Dont replace just one O ring on the injectors. You need to replace all when you replace them. It sounds like you still have O ring leaks.

Remove tank and use EXPOXY glue its available from Auto-Zone or almost any auto parts place and use to fix leak. It can withstand high temperature and cold temperature will work well. Good Luck and thanks for using FIX YA

relay is under dash on driver side behind cruise control box. You tube has a demonstration on there for 92 accord.
