(Solved) 3rz starts and dies, no CEL

According the ECU guide above. The E8 pin 14 is called FC.
I assume it’s Fuel Control?

 

Yea it is, there's a typo on the diagram I was looking at. It actually should be E8 Pin 24 (Brown) that is the other ground.

 

I had the lead hooked to a positive wire black and red

 

Ok. Now I’m back on track.
I was a bit lost for a second.

 

Do you have a test light that we can load test the powers and grounds with?

 

If it has been swapped they must have swapped the whole harness because i have the dash tore apart and everything under there is connected

 

I was tired and I had a headache last night so I wasn't really all there at that point.

 

I have a regular test light that shows voltage but i can make a load test light if i need too

 

I will start back tomorrow morning checking more things that is mentioned it’s started raining here and i have 2 other clunkers in my shop being worked on right now

 

I’ll swap you a headache for some square walls.
I was hanging gutters “in between” rain shows.

 

I'm just trying to be 100% sure powers and grounds are good because voltage checks alone can be misleading if there's high resistance in a circuit.
Just have a look at the first 2 videos in the post below for examples.

Nope I'm good, I'd rather do diagnostics all day than than start doing carpentry work in the rain.

 

I’ve seen them.
I’m bad to take the OPs word when they say things are “good”.
I don’t alway remember that not everyone knows how to do the checks correctly.
I just take their word, and move on. Which can get you into trouble sometimes.

 

Now you know why I don't hang out in the 1st gen section much

 

Yeah, they tend to be “well modified”.
It is like I belong here anyways .

With the day I’ve had, “making it work”.
I guess I can “make a 1st Gen work”……
One and the same at this point.

My life has been “It’s not right, but we have to make it work” lately.
I need a break.

 

Oh I could figure it out if I knew all the details but by the 2nd or 3rd owner those "details" are long gone.

At this point I'd just be happy if a part I put on worked the first time and I didn't have to go through 3 or more to get one that lasts more than a week.

 

I haven’t got to load test it yet but i grounded the green and yellow to see what would it would do and the truck is running good but no check engine light still

 

If i ground e8 pin 14 at the ecu plug truck will not run just starts and dies. If i ground it at the c.o.r the truck runs good?

 

If your on the correct wire then you have an open in the wire between the PCM and Circuit Opening Relay, there's an intermediate connector (IK2 Pin 5) that you might check.

Still doesn't explain no CEL and no com though.

 

On the top row of the pins notice there is only 3 pins sticking out and on the plug that goes into it there is 4 and the 4th one happens to be the green and yellow
