Car has power, wont start?
Ok 07 chevy tahoe 113k miles. Never
any problems so far. Raining all day
yesterday and night before...go to
leave and it wont crank. No sounds on
turn over just pure silence, turn the key
back to off and try again and it cranks
right up..every check light came
on...engine, airbags, stabilitrack off
and some more. So I turn it off and try
to get it to crank again and nothing..no
click or clicking. It does have power.
All of my interior lights, radio, and
headlights come on but my doors wont
lock/unlock, windows wont roll up or
down when I push the buttons on the
door panel and also my key fab wont
lock/unlock my doors now that this
happen. I just replaced the battery in
my car less than a year ago so battery
is still good. And the key fab has been
working until after I turned the car off
after getting it to crank then trying to
recrank. Ive read a lot and ive been
pointed in the direction that this may
have something to do with my
electrical board I do believe its called
the epc or epu?? Does that sound right
because some places I read said if its
electrical board you have no power
Could be the BCM (Body Control Module). Everything you have mentioned is controlled by it. HTH. -Jim
Did you ever find out what was wrong? My 06 Tahoe is doing the same thing. Doors usually unlock when I put it in park but it has been flaky lately and will unlock if I give it a little gas. Now it wont start at all.
it ended up being my alternator that went out. i finally got it to crank 2 days later and drove it to the nearest shop i could get it to.
Whack the side terminals and cables with a hammer, then tighten them again. If it still doesn't crank remove the one with the starter cable on it and rough up the two cable ends there with a rasp. You might have to file them a little thinner as that bolt is too short.
If you have all your lights, and other stuff it wasn't the alternator. If the alternator quit you would have no power. Watch your lights when you turn the key. They don't dim at all do they. If batt power was going to the starter the lights would dim. It's your starter cable.
Mine is doing this right now, After a whole day of the car in the dealership and them not being able to find anything, I was able to get the car to a parts store and then get it to not start up. Mine gave me the the PO573 error which is Cruise Control /Brake Switch code. I was able to pump the brakes twice to try to reset the switch and got it to start right up. Now we know what the problem is!
I think i have the same problem.. i have a 2002 Tahoe 169k miles and it never used to do this. i turn the key and nothing.. no clicks or sounds. i changed the transmission and fuel pump at around 140k. I charged the battery with a mobile battery charger (with jumper cables) and it turned on no problem. i wake up the next morning and it did the same. i have no idea what it is and i dont want to pay 250 to check what is it... Help anyone?
Check your ing A fuse under the hood
I have a 2008 tahoe. I would loose power to my cluster while driving once I turned off the truck I would not have any power at all. I ended up changing the negative terminal cable and it's running like a champ
2002 Chevy Tahoe some times it starts other times no I would wait 30 to 45 mins then try to turn it on and it would wrk I have a good battery good alternator and now a new starter cuz I thought that was it wen I would hear clicking sounds .and now. Same thing idk wht it is
Ok by mistake I put water on my gas tank and my fuel pump went out I replaced it and now it cranks but doesnt stay on at all is it the crank sensor or the spark plugs??
hi my name is Steven I got a 2003 chevy tahoe and my fulpump really was bad and I put a new on and it steal would start the light come on when I tern it on so I no it's not the battery I hope u can help me thinks
Hi Steven. You'll be better off starting a new thread so everyone can see your question. But, to me it sounds like your fuel pump. Take a hammer and hit the center bottom of the gas tank. Two or three times will be good. If that gets you going, it's definitely the fuel pump. HTH -Jim
My truck radio turn on but it don’t start up
