Headed under the hood to search for the the mysterious issue of the friggen thing wont start now.......Running out of things to do,,,,

 

BLADE..... Tell how me how to do this load test you spoke of Friday,,,,Please

 

You take a Headlamp and use the battery and Pull a Load over the wires thats in question

now have you checked for continuity yet???

sometime continuity ok but Fails Load test

Do continuity first its easiest for me anyway

Did I give you the pins to test the other day I cant remember????

 

let me find the FICM Pinout

 

---------------------------------SO LIKE THIS---------------------------------

--FICM PLUG END PIN#-------------TO------------PCM PLUG END PIN#--------

PIN#5--------------------------------TO-----------------PIN#19----------------
PIN#9--------------------------------TO-----------------PIN#28-----------------
PIN#10-------------------------------TO-----------------PIN#20-----------------
PIN#30-------------------------------TO-----------------PIN#37-----------------
PIN#31-------------------------------TO-----------------PIN#26-----------------

ALL these circuits should have continuity and carrey a Load Between them doing this will verify the condition of the Wires

The FICM plug you will be probing is the closest one to fron of truck FICM sitting install position

The PCM IDK what one maybe try to trace wires from Ficm to PCM by Driver Battery and locate it that way I have a Pic it wont let me Post it here


Normaly the Pins are Numbered on the Plug END you can see numbers when you unplug it


CLEAR AS MUD RIGHT???????

 

Thanks, Just got back home will get started on it.....

 

Scan for DTC maybe a helpful one my pop up too

Hope you find something

A load test would be using a Light and the battery strip a peice of wire and hook to battery positive and plug into harness and hook the light at other end basicaly want to make these circuits in question to carrey a Load across it the light should be bright and NO Flicker

But test continuity first as thats the easiest

 

Thanks again....got the load test did many times, just never knew what the its name was......

 

Man I was Hopen you said I found the Problem LOL

the Suspense in Killen me LOL

 

Its best to use a BIG Light Bulb for Loasd Test pull as much juice as possible over it

them little test lights dont pull much

I think Cheezit has a HeadLight rigged up for this kinda testing

 

PIN #10 to PIN #20 does not load test or OHM

 

There you go thatsa IT

Maybe you can splice a new wire In would be cheaper than a Harness anyway try it see if it starts then if you want a new harness then so b e it


Thats the Camshaft Circuit from PCM to FICM

 

Id rig a temp wire up or something see if it will start

 

Yup, Working on that now....

 

OK Cool my Fingers are crossed
