Question about 1996 Honda Odyssey

1 Answer

Engine Floods after brief start and run when cold -then shut off

Our 1996 Odyssey flooded out and wouldn't start after backing out of garage on a 40 degree day, turning it off to wash it, then pulling it back in the garage 20 minutes later. Engine was not wet. Garage restarted it by holding foot to floor on gas pedal and cranking 5-10 seconds. Apparently this stops the fuel flow.

Car running fine now. Never happened before. Is there a problem?

Car has 160,000 miles on it. Well maintained. Runs well and gets good mileage 20 city to 27-30 highway.

Local mechanic determined engine was flooded and started it by holding throttle to the floor and cranking 5-7 seconds - then the engine sputtered to life. It has run perfectly before and since and I'm at a bit of loss to understand why this occurred this one time - so far. It's been driven now 5 days with no problems.

Injector sprays too much fuel after starting. Engine floods out


Suspect (potentially) either a stuck injector, or a failed/failing fuel pressure regulator. One sign of a failed fuel pressure regulator can be gas in the oil. (I suffered that side effect, along with bogging, and black smoke rich running, worsening as warmed up, turned out to be fuel pressure regulator). If the injector is loose in the throttle body, or has bad o-rings, can also cause some wonky behavior. Good luck.

Restating 2000 odyssey after warmed up


not sure what that means.
lets start over.
your saying car runs great, cold then hot.
then hard to restart a hot engine, right?
the light thing i dont understand
first off, when you stall and engine or just key ON.
the lamps all self test (read the operators guide there)
this is only a lamp test.
odd, the most important is skipped the CEL, check engine light.
is the engine stalling?
hot restarts, fails are: many.
  1. injector leaking at shut down.
  2. ECT reads to cold when hot. can be below caused
  3. Engine thermostat stuck open and restarts are over rich and floods. that hot engine must be at 180F or more,
  4. never did a 60,000 mile tuneup this decade?
  5. Fuel pressure too high.
i do tune ups first.
then check coolant temperatures, hot. 180F min, and holding or i kick the thermostat to the curb (new stat time)
if it sill dont want to hot start
out comes the scan tool
i scan it, got DTC errors.
is ECT reading 180F ? or above?

that is start on diagnosis.

My car starts fine when engine is warm. I turn it off then try starting it again. then starts up and shuts back off. does it like 3 times in a row. then I wait a few minutes then it starts up when I push...


stalls, are complex
if the engine is good (compression at spec)
it this list.
1: lost electric power to EFI system or spark.
2: bad fuel.
3: bad spark.
4: bad fueling. (too much or too little.
5: EGR stuck open
6: ISC dead. or IAC dead. (idle air valves failing cold)

there are tests for each.
cold start failure only ! all else good, engine tuneup done?
1: ECT fibbing like oh'bummer. (signals water temps of alaska in Panama? "floods, and your right foot helps./..........
2: IAC (cold start fast idle air valve bad) same for right foot....
3: check engine light on running? is it?

ECT can cause gross over fueling.
the IAC dead will cause gross under AIR which in fact causes flooding (less air plus same fuel = flood)
bad fuel.

Floods when cold


Define flooding.

  1. Black smoke out of the tail pipe?

If the fuel return line is plugged,it will flood.If the fuel pressure regulator has lost its vacuum signal ,it will flood.

If there is a large vacuum leak,the O2 will see a lean condition and cause the rich condition.gas mileage will suck,big time.

This "flooding" happens when the engine is cold? ONLY?
Be sure the air filter is not clogged and the PCV is not plugged up solid.
Also,there are a few tubes from the valve cover that vents oil vapors into the air filter housing.

During this flood mode,hold the pedal to the floor and shut the engine OFF-it should NOT keep running.(Leaky injectors)...

Do this when engine is hot and cold.

1989 mpv mazda does not start on cold mornings and days


I'm assuming the engine cranks with the starter but does not start and run.

check the operation of the cold start injector. This is a separate fuel injector that injects fuel into the intake manifold to help richen up the mixture for cold starts. It operates on a timer that is linked to a sensor that measures engine coolant temperature. Once warm or the timer runs out, the cold start injector is turned off. Other things to check:

Fuel pressure too high (floods engine through cold start injector), engine coolant temp sensor or intake air temp sensor is stuck at full hot (doesn't allow enough fuel for cold starts), fuel injectors are leaking (floods engine with fuel).

Starts good on a cold start. As it warms up, it


Sounds like the automatic choke is sticking.

Engine floods after shut off...replaced fuel pressure regulator, no change...


One or more of the fuel injectors are leaking when 'off'. Start the engine after being off for a while, let run for a moment or two, then shut off. Remove and check each spark plug for being black from excess fuel. Any that check black insulator, replace that injector. Hope this helps!
