I will try that, 2 connectors look new the middle and left one. Thank you sir!

 

Is this truck new to you

 

yes I've had it since june

 

Any help would be appreciated Bump

 

So is it still starting and running

Have you checked battery cables and grounds clean terminals follow ground wires to frame and engine clean and ohm cables

It sounds like it's going to need extensive electrical trouble shoot

You can use the SGII when it won't start to see what it's missing you can also use it while running but you may it see a problem



Do you have the SGII programmed with all the gauges or is SGII still basicly stock

With a problem like this it would be better if it didn't start it's easier to see what's missing/problem this way

Maybe it's loosing cam/crank or FICM sync so make sure to check those when the no start condition is present plus you have a DTC for it could be from extended crank or it's just flakey/bad sensor

 

I cleaned grounds terminals and checked ohm cables are good sg2 is programmed I did my self I do not get com with the ficm icp ipr no codes other then the cam and crank it ran today fine started ok had trouble the fist time but this afternoon I went to start and nothing all lights and no crank but magically after dinner it starts up
check engine light was blinking I can hear the fuel pump turn on and off in sync with the check engine light it would blink on and off about 10-20 times before it some how holds connection and stays on wait to start goes off I get crank and fires right up...fml

 

Might be worth throwing a new PCM power relay in it

Sound like it looses everything so be worth making sure PCM is getting good solid power

 

I found this online make sense to me it's gotta be a bad wire between the dist block to the pcm. I swapped out relays already 😡 I'll check the ebp sensor
-Check batteries and connections, voltage should stay above 10 volts during cranking
-The PCM controls the starter, so if PCM voltage drops below 9.5v the PCM shuts off and won’t control the starter.
-If the fan clutch shorts out it will draw the PCM voltage to zero, and thus you will have a no crank situation.
-EBP sensor shorted out will shutdown PCM

 

Yes that stuff crossed my mind
It could even be a bad ignition switch

You going to need wire diagrams I can't post them now there at home

Also as you ohm wires out make sure they are open to ground unless it's a ground circuit

In this case I would probably start the testing of circuits at the ignition key go from there

If it is a bad sensor or something you should be able unplug the culprit and get dash lights to settle down

 

What does SGII show for V-ref

 

Guess v-ref won't matter since we need to see it when it's acting up but the problem is there won't be any communication with SGII at that time

And it might be worth trying a PCM off another truck cause it could be bad PCM

 

So it's acting up again... No cvi reading no reading on anything except voltage not even eot the ignition switch was replaced when I bought it along with that white box

 

Just for saying,check to see if the guy made a full connection on the starter switch. Can't hurt to look.

 

Been a few since I opened this link

may need some better diagrams but its a start

 

Thank you so much!!! I'll let you know what I come up with
