22re getting to much fuel will not run or start any ideas.

 

Lots of ideas. We need more from you. And CEL codes? I assume you when you said too much fuel you have raw gas on the plugs. Maybe smell it out the exhaust. If plugs. Have you checked all 4 plugs are they all wet? Do you know you have spark? Have you pulled a plug and seen if it will spark with the wire hooked up? Was you truck running perfect and then all of the sudden developed this problem? Or is this something that has been building? I.e. poor acceleration from stop hard to start ect... Just way to many variables. We need more info from you

 

^ Answer this guys questions. Help us help you.

Sounds like the cold start injector may be staying on?

Check your TPS and AFM.

Welcome to the forum from across the lake!

 

it has spark I pulled the plugs and turned the key over and its pouring gas out the cylinders I changed the fuel pressure regulater that did not help the the truck is a 88 just put and 86 motor in it. It ran fine for 4 weeks then would die after running fine had to pull it to get it started again then ran fine for a week then then I was driving it and it died again and will not stay running on its own unless you unhook the injectors and just spray starting fluied in there. not sure what are cel codes.

 

Check engine light is CEL. Use the search feature on here to find the diagnostic port make the connection and look for your codes. It's really simple and requires a pad of paper and a paper clip or small solid wire. Let us know what you find. Just search on here if you don't find it with the site search engine then use google with yotatech as one of your key words.

 

Here are the codes.

 

what is the afm and csi I will try the code in the am thanks every one that's helping.

 

On all equipped vehicles the check connector (near the ignition coil) or diagnostic connector are located under the hood in the engine area on the shock tower (passenger side) or near the junction or relay block (driver's side). A small plastic cap covers the check connector terminals and hinged plastic cap covers the diagnostic connector. Each terminal is mark inside the diagnostic cap cover for proper identification.




Check that the initial conditions are met.


2. Turn the ignition switch ON but do not start the engine.


3. At the diagnostic connector or check connector, use a jumper wire to connect terminals T and E 1 .


4.Observe the CHECK ENGINE warning lamp on the dashboard; read the code(s) based on the number and rate of flashes.


5.If the system is operating normally, with no codes stored, the warning lamp will flash on/off in a constant, unchanging pattern. This is the System Normal signal; the ECU is acknowledging the request for codes but has nothing to report.


6. If malfunction codes are stored, the light will blink every 1 / 2 -second. The first number of blinks will indicate the first digit of a 2-digit code. After a 1 1 / 2 second pause, the second digit will be transmitted. If there is more than one code stored, they will be separated by a 2 1 / 2 -second pause. After all stored codes have been transmitted, the cycle will begin again after a 4 1 / 2 second pause. The codes will continuously transmit until the jumper wire is disconnected. Even when transmission has stopped, the codes remain in memory until the memory is cleared.




If more than one code is stored, the codes will be transmitted in numerical order from lowest to highest. The order of the codes does not indicate the order of fault occurrence.

7.Record the codes as they are received.


8. Disconnect the diagnostic jumper; switch the ignition OFF .

 

Afm mean Air Flow Meter. Located Under hood, driver side, front engine area, rear of headlight housing, mounted in top of air filter housing.

 

Wow use the search feature. It's there for a reason.

 

did the test its flashing code 21 oxygen sensor but on my its not hooked up and the truck ran fine with out it could this still be a problem

 

Yes if it is not hooked up that could be the problem. Hook it up if you still have the sensor and see I that helps.

 

I hooked it up it started ran about 4mins then over fueled again not saying anymore codes I don't no were to start.

 

You should check the fuel pressure. Make sure the Afm flap isnt stuck open.

 

I did check the fuel pressure it was good how do I check the afm flap.

 

This is the afm it sits ontop of the air filter ..



Flap is here .


Push the flap with your finger. I believe it should spring back all the way. If it stays open. It could cause the truck to fload.

 

I pushed the flap and it comes right back. I did clear the codes the 21 code is gone now after hooking up the o2 sensor. now code 52 is showing I think its a knock sensor that would not make it foul out would it

 

put a new temp sensor in it today and stays running now seems to be fine.

 

Awesome sounds like its fixed.

 

well I thought it was fixed it runs until it gets warm I drove it down the road about a mile then it died again let it sit for a hour or so will run again. there is a part on the pass fender that has two yellow plugs it gets realy hot when I unplug them it will run again but rough.
