06 cad escalade intermitently when started batt. light stays on, all guages shut off stabilizer lite on, still runs fine, 6 processers have history code U1016; one other code is on hvac hiltory # U1301 & BO424. any help is appreciated.

then starter motor is dead, and is silent, and will not crank the engine at all(I GUESS)
correct?
starter dead is just 6 causes posted her 1000 times and 1million times if you googled why is my starter dead
again just for your causes.
yous said jump starts fail but no words at all is the starter motor dead silent.
I can push start my car but it has a manual transmission.
all IP cluster freeze when engine dies and goes to self test mode , glows lamps.
scan the PCM now and it tells you what failed with DTC error as you crank any dead engine.

causes
battery cables lugs loose or rusty cleanm em.
1:battery is bad, charger it up first or replace it if charging fails or load test fails (those are TOOLS)
2: fuse blown. to IGN switch (check all fuses if savvy)
3: IMMO lamp not unhappy, bad key, lost 2nd spare key? oops. but cuts spark and confuses many.
4: keyswitch bad ST pin failing and BAD.
5: PRNDL switch bad (a/t box) shift tO N=neutral and turn key to ST crank position, cured?
6: starter relay bad.
7: starter motor dead and bad.
8: all wires connecting all this up above bad (we use a volt meter) to find all these.

THE STARTER MOTOR CAN BE HOT-WIRED TESTED IN-SITU, AND TESTED KEYS IN POCKET SAFE.
POSTED VAST TIMES THIS) OR ASK HOW. OR GET THE CAR SERVICED, BY FOLKS THAT KNOW HOW.
SKILLS AND TOOLS BOTH. YOU DO NOT HAVE.

TURNS OVER(EEKS)
50% OF POSTERS MEANS STARTER IS DEAD."NOT TURN OVER"
50% OF POSTERS USE THE WORD FOR ENGINE RUNS OR NOT. (CRAZY NO?) THIS USELESS PHRASE?
BEST IS SAY CRANK AND AVOID THE SILLY WORDS TURNS OVER.

CRANKS AND WILL NOT START (50 CAUSES)
OR WILL NOT CRANK (SURE IT CANT START)AND 6 CAUSES, BUT MINE PUSH STARTS ANY DAY.

IF THE STARTER MOTOR IS SILENT SAY SO
OR SAY IT CLICKS ONLY OR CHATTERS ONLY.
THE DEAF HELPERS CAN NOT HEAR YOUR STARTER , EVER. UNLESS VIDEO OF IT POSTED WOW..

I have an '03 EXT and when my service stability thing was happening I took it to several shops who said it was fine. It wasn't. It cost me $2,700.00 to have my rear bearings done. Now my engine light is on and I just replaced my bloody alternator. This truck I bought new off the lot and it's been a hassle the whole time I've had it.

Could be the auto shutdown relay is getting weak. Try swapping it with the horn relay.

unhook hot wire to alt at night if batt is up the next morning it is the alt

It's not the coils . It's the PCM , transistors (driver) inside the PCM are fried .

BFC that body function controller. BFC batt fuse controls .the body function controller .its part of the PCM.the BFC controls anti theft system. your interior lights -drl lights- radio -door locks.if your check engine light is on take it to dealership.because your BFC and PCM works together. your car could shut off. that unsafe.when you on a busy highway.you have electrical problem.not a home fix.

check fuel pump resister. its conector is by the batt. pump runs through it in run, not for 3 sec. when key is turned on. thats why it will start and then quit this happend to my 99 gtp

i had the same prob. w my 97 grand am. i bought a new ignition switch and installed it...after installing you have to reset the theft system. all you have to do to reset is turn the key far enough for it to bump the motor over then leave the key in the run position for about ten to twenty minutes...might hook bat. to charger cause if it dies in process you have to start all over...the theft light will either blink then stay on or go out completly....
