Hello. Welcome to Just Answer. Please allow me to assist you by discussing your concern.
Question: The vehicle was running fine until you encountered a rainstorm. Is this correct?
This is true, but upon starting it the next day it ran fine for about 5 minutes then died while sitting at a stop sign
from then on it would start right up just fine but then die only moments later
Is the vehicle available?
Please go out to the vehicle, and pull the passenger side kick panel. In that area, there will be a relay with 6 pins on it. This is the Circuit Opening Relay. Check to see if the box is corroded, or the wiring connector has corrosion in it. This is the most common culprit. Let me know if there is corrosion/oxidization, etc on or in the box.
sure. give me a moment
the only thing I see behind the passenger side kick panel is the ecu, and it looks fine... drivers side?
It is higher up on the passenger side. Behind the front of the dash panel
sorry, i hope im not missing something here, but i dont see a six pin relay, just the ecu, the wiper control behind the kick panel
No worries, we will back track
DO you happen to have a 12 volt DC testlight, or a DC voltmeter?
Open the hood, and locate the diagnostic connector. Under the lid of the connector there should be a label. Look for the Fp cavity.
Ground your black lead on the voltmeter, and insert the red lead into the Fp terminal, ensure you make good contact.
Crank the engine
Observe the voltmeter.
Advise if the voltage drops to zero when it dies
Or right before it dies.
Another thing...you mentioned the white with a black tracer on the air sensor. Did you have power in that wire or not when you checked it, and, how did you perform the check?
im at a loss as far as the data link connector... i cannot seem to locate it. there is no diagram anywhere either that indicates what terminal would be Fp.. .
That presents a problem.
Let me ask you this
Did you have power in the green wire on the air flow meter?
the white with black tracer read 0.00 . i had the key in the on position , black lead grounded, red on on the terminal in the boot
Please test the green wire for voltage, and see if the voltage there drops out and causes the engine to stall.
Air flow meter = air sensor
12 volts on green
Start the vehicle and see if the voltage drops
voltage climbs when started
does not drop below 12
The diagnostic connector should be on the passenger side, near the fusebox, on the windshield side of the fusebox.
no dice. it is either not where it should be or there is something wrong with me
Let's do this. On the injectors...
You have a blue or a yellow wire going to them, and, a white and a white with a red tracer
See if you have voltage in the yellow and blue wires when the engine is started. If so, see if it drops out when it stalls.
full voltage, doesnt drop... what's weird though, is that it ran much longer with one of the injector plug off
on the air flow meter, the green wire is terminal 1
on the air flow meter
The white with a black is terminal 1
the green is terminal 2
the brown black is terminal 3
the black is terminal 4
the blue with a red trace is terminal 5
the yellow with a blue is terminal 6
the yellow is terminal 7
on the airflow meter, with the wire connector disconnected:
open circuit with the air flow meter door closed
between terminals 1 and 2
with the door open, the resistance should be direct continunity with the door open
Move the door open until the resistance changes, and continue moving the door, see if the resistance drops out
terminals 6 and 3: 20-400 ohms with the door closed
terminals 6 and 3: 20-1000 ohms with the door fully open
terminals 5 and 3: 100-300 ohms
terminals 4 and 3: 200-400 ohms
terminals 7 and 3: 2-3 K ohms at 68 degrees.
all resistances check out within the parameters you supplied
Does the vehicle start right back up when it stalls out?
How long does it run, from start to stall, in minutes?
it has been running for about 3-6 seconds then cuts out fast. it actually just ran for about 5 minutes which hasnt happend since it first died. i was able to put in gear and move it forward and back then it died again.
This vehicle has all the earmarks of a circuit opening relay that is dropping out.
It would be most helpful in our diagnosis to locate this relay.
According to my book, it is on the passenger side of the dash, perhaps above the glove box.
Lets do this:
Remove a plug wire
Start the vehicle, and hold the plug wire close to the engine, to allow spark to jump. See if the sparks stop jumping right before the engine stalls.
Use insulated pliers
just the wire? leave the plug in...
yes. Leave the plug in. Disconnect the wire, hold the boot about 1/2" from the metal of the engine. You should see the spark jump. it should be blue-white, and not orange
it sparks. but now it will barely run at all, just enough to see a spark maybe 2
btw, my truck is down 40 stairs around a corner plus 100 yards away... im about ready to trow in the towel...
Based on your statements, You either have a bad circuit opening relay, or the distributor/igniter has an issue. Without checking Fp on the check connector, we cannot verify if the fuel pump is dropping out or not. The air flow meter appears to be ok. Voltage at the injectors is good. That leaves us with eithe the circuit opening relay, the distributor/igniter, or the computer. More diagnosis is needed to sort that out.
voltage on the green wire indicates that the EFI relay is good.
is it possible the previous owner removed the data connector or that my 85 never had one...?
Sorry, I was not aware of the distance involved. :-( apologies
not your fault no worries
I wish I had better information on this. All I have been able to do is tell you what is not wrong...
well at least i can save the mechanic a little bit of time tomorrow . thanks for your time though. appreciated
You are welcome.
Thanks for choosing Just Answer.
FYI.. i figured it out.. I assumed you knew that an 85 toyota pickup was different from a 95, apparently you didnt because you sent me on a wild goose chase for parts that did not exist on my truck!!! I thought you were an expert....? The relay IS NOT, i repeat IS NOT on the passenger side, it is on the drivers side, just like i suggested but you said No...you insisted it was somewhere on the passenger side. After talking to a REAL mechanic I was not happy at all the time I wasted chasing down things that were not on my truck ie, there is not Data link connector on the passenger side...its 2 plugs and they are on the drivers side.... WTF? Did you do that on purpose? Or are you really that ignorant...? It's not like you didnt know it was an 85...i told you this multiple times....
What a joke.... running up and down stairs looking for things you insisted were there making me feel crazy.... I'd give you negative feedback but i'm not that mean, although you deserve it... hopefully this and the letter to just answer will be enough to prevent so called "experts" from making others feel like they are losing their minds... Have you ever even worked on a toyota truck pre 1990???? didnt think so....
i appreciate that you gave me some of your time...too bad it was a complete waste of mine
Young man, I do not normally reply to false accusations and negative responses like this, but, this time, I am compelled to tell you that I was reading information to you from the official Toyota factory wiring book. Besides....1995 trucks do not have air flow meters, they have mass air flow sensors.
In any case, I am glad to see you got it sorted out.
have a great day.
