Removing Water from Fuel System!

[RangerMan64]

I have no idea how to pull codes from an OBD-1 computer system..

Go to the main TRS page, then to Tech Articles and you'll find a good article on pulling KOEO, continuous, and KOER codes with a paperclip (look under EEC-IV).

Mark, even if it is the Map sensor, shouldn't the onboard ECM go into a "limp mode"?

Even in limp mode the engine should run half decent(like a carbed motor)

Would replacing the MAP get it out of limp mode?

Only if the MAP is the reason it is in limp home mode.

Yes, the MAP sensor could clear up most of the problems...if not all, if they are related to that sensor...that's a fast, inexpensive first up solution...

I do not recommend going to a dealer to buy that part simply because they can be quite expensive and are not usually returnable...

But get two if you go to the junkyard just in case the first one is actually bad...

I am surprised that nobody has suggested simply unplugging the MAP sensor while the engine is running. Try doing that before you buy anything. If you notice no difference in how the engine is running, then you may have a bad sensor.

Normally when you unplug this thing you will notice an immediate change, usually it sputters and coughs up a lot of black smoke for a few seconds before stalling.

an easy way to tell if you've got water in your fuel is to syphon some fuel out of the bottom of the tank after it's been sitting for a while, water should be at the bottom of the tank if it's in there. get enough out to fill a clear 1 gallon container, if there's water in there it will seperate from the gas.

Does AutoZone still do the free checking?

O'Reilly's does, I don't have a Autozone locally.

Does AutoZone still do the free checking?

I "THINK" any and all auto stores that pull codes for free ONLY do it on model years 1996 and newer??

Here in Kansas auto zone and advance auto still provide the service, I am not sure about others.

most auto parts stores will only pull '96+ codes period because thats all they can do. OBDII was mandated in '96, meaning a generic scan tool will pull codes out of any make/model. anything pre-'96 is manufacturer spacific and it would cost autoparts stores a small fortune to buy every specialty scanner out there.

but a scan tool is not required to pull codes from a pre-'96 ('95 in the case of the ranger) ford. a paperclip and notepad w/pencil for jotting numbers down works quite well.

Except my wifes 95 T-bird, 4.6. It's OBD-II as well.

 

[Wicked_Sludge]

OBDII was manditory in '96. ford and many manufactures started early to make the deadline, thus many '95 and im sure some even earlier vehicles from different manufacturers are OBDII.

but EVERYTHING after '96 is OBDII, while only SOME pre'96 vehicles are.

Well did you're test, it died, so I am assuming the MAP is OK. I think I still have water in the fuel. I don't have any gas cans or tubes so can't really siphon that way. Do I need to replace the fuel filter after I get the water out of the system?

 

[Wicked_Sludge]

yes. water rarely comes without sediment and other contaminents.
