Sensors malfuntioning??

 

I did replace the 12 volt in the engine compartment ..I'm afraid of draining the hybrid battaries so I'm trying to be specific in my actions .I'm very confused .so to recap.
The motor is factory replacement with 35000 ish miles the rest has 156000
Oil is changed regularly
New Battery
I checked through the valve on fuel rail for fuel it's there
It runs for 5 to 8 seconds or at least appears to .
I have run out of fuel as embarrassing as it is twice and this truck doesn't like that it jerks and rattles then shuts down
But it's been awhile since it's happened
I have the hood open supposedly it keeps the hybrid part turned off ???? Maybe won't run down the rear battery
Nothing obvious you could eat of that motor it looks brand new so nothing burnt twisted or broke off that's obvious to me .


I will add that since day one that i have owned her that the a/c compressor makes a horibble sound sometimes faint sometimes louder by turning it off and on it usually went away .the air still blew very cold but for the info it was not normal by anymeans just not interfering with the running and I don't run the a/c very often so also not important.

Other then that I have had little indication that I can think of as of now of where to start .
I parked it as always and now it won't run .


Thank you very much

 

When the engine stops, can you put it in Drive and will it move?

If not, you are at the point where a scan tool is required.

 

No it doesn't move ..it also doesn't go to auto stop which is what your also getting at... I guess I'll have to tow it.i want to tell them what to look for and not be a Victom of a parts chaser although the codes may tell the story immediately .I hate being at there mercy so bad stories...

 

Well I had it towed to the stealer and they informed me I am in need of a hybrid power train control modual at a cost of $1,237 plus a $135 seal kit and 7 hrs book time.. ouch !!!!!
Codes thrown... PO601 and. P0AC4 ...

 

New terminology for the part being replaced it's now being called a drive motor generator power inverter module part number 12647259 too nice way to explain a $2,037 repair bill new terminology for the part being replaced it's now being called a drive motor generator power inverter module part number +1-2647259to explain a $2,037 repair bill but I must also add it has been a very nice truck.

 

Hopefully it should fix everything! I'm surprised for the premature failure? If yours less is than 100k miles it will be covered by warranty? But you said it has 156k miles already.

 

It does have 156000 .. not knowing allot about this item I can't command but not much mention on the forums.we will know Tuesday how well my $2000 is spent.

 

7 hours is 4 too many. Did they clear codes in this case and see if 601 comes back?

 

601 did come back .gm wouldn't let them order the part without confirmation of code the part I understand is a restricted part u guesse so they had to get "permission to order.could this be related the the winning sound I have had since day one when I turn the a/c on ? I can turn it off and back on it usually goes away or diminishes .also the book says 3 hrs ?
