So with all the cold and short drives flooding can be a real issue. Post up solutions to this problem to prevent constant flooding if someone runs to the store in 10 degree weather.

In other news... I went to the store tonight to pick up a part and only ran the car for about 8 minutes. The thing flooded as can be expected from going for only so long and being turned off pretty much right away. Basically I ran the battery down trying to get it started. Then I had to have someone come help jump it and be my unplug that and plug it back in person to unflood it.

Finally got it started and got home.

 

1). You need to have a battery that is in excellent condition.
2). Run 5w30 motor oil.
3). Make sure the ignition system is in great working condition. Preferably with high output coils.
4). If you suspect it is going to flood, hold your foot all the down to the floor when cranking.

 

Is this carbed or FI? If FI, it may be time to have the injectors serviced. If carbed, it may be time to service/clean it, perhaps even a rebuild.

 

Fuel injected. Issue is when I pull the plug off of the coil to unflood it it will crank and fire up. It will stay running for a second and die due to lack of fuel. When I plug it back in to actually start it it will putter like starting once and then die. As if reintroducing fuel kills it. Now with someone standing by I can remove the plug go to start it and when it starts put the plug back on and it be fine. WTF?

Could this be the cause? I doubt it but maybe...

 

Afm should be mounted flat, not off kilter. Instead of pulling the coil wire, pull one end of the engine fuse in the fuse box under the dash. That way when it starts to catch, you simply push the fuse back in while cranking.

If the engine is up to operating temps when shut off, restarts should not be a problem, unless you have leaky injectors or a tired engine with low compression.

 

First thing I have everyone check that has a Se and flooding problems is the operation of the AFM. When you turn the key to the on posistion do you hear the fuel pump come on?

 

lol err, is that an oil filter cartridge on your air pump hose?

try cranking it with the pedal to the floor and the fuel pump on.

 

I'm just going to install a switch in between the tab off the coil and the line for the fuel rail. That way when it starts to fire with the switch off I can flick it on and away I go.

 

Sounds like leaky/cracked injectors. Clean or replace as needed.

You could just run a wire from the plug, thru a switch, and back to the coil. Wait until it fires up to turn on the switch. That's just a "Band-Aid" method, though.....

 

Yes it is until I can by the proper filter. Works. Done it plenty of times before on other cars. Okay... so I think the issue is that the AFM is tilted. hmm...

 

I'm gonna throw the stock air box back on in the proper mounts and see what that does. I'll need to get an elbow for the AFM adapter plate I have to mount the cone filter sideways to clear the hood

 

If the issue is flooding, you need to cut fuel flow, not spark. I start and shut down my 2nd gen while it's still cold all the time when moving it around the driveway, never have had restart problems. I did have the injectors cleaned, even though it had less than 100k on the clock at the time.

It's best to do it right. Fwiw, if you do have a cracked injector, they have been know to leak externally, leading to an engine bay fire. Not a pretty sight.

 

Still did not answer my ?

And yes it does sound like a bad injector.

 

Yes I can hear the fuel pump.
I think I can rule out the injectors since before I went messing with the air box I could start the car each and every time no problems(aside from the -25 degree day before the tune-up). It's most likely because I F'ed up the air flow by letting the AFM sit loose and at an angle like that.

 

I've never had a problem with my car starting after flooding. Of course Jose rigged the choke to go to 5,500rpm and above..........

I can even get it started with a near dead battery while flooded. It sounded like a blown rotor but it managed to burn off.

When my car would stall out after running a minute it was because of gunk in the fuel lines...... I had to take a aircompressor and carb cleaner and clean out the lines.

Well I doubt this helps but anywase...

Leaking injectors? Bad coolant temp sensor?

You should try to fix the problem rather than find a way to live with it...

 

+1

 

You are agreeing with yourself? I don't get it...

 

Yeah, get your afm level and secured, should help. However, I don't understand why it would cause problems retarting when cold, unless the afm door is binding due to the cold.

 

Well... put the stock air box on and the thing fired up no problem. That was it.

When I meant flooding in the cold I am just referring to the stories people tell of flooding in the cold and the car being impossible to restart. I'm gonna do some research into the injectors today and this weekend I'm gonna dig into that.
