hey every one i just got my car tuned o 2 days ago we rased the timeing a little and made it run a bit leaner
and i achived good numbers 370 whp and 315 wtq on the vortech kit.
after we did that we reset the ecu i belive we just diconeced the battery for 2 min. then pluged it back in the then re dynoed the car made the same #S
i left the shop most of my lights wher on the dash but after 1 min of driveing they all went off i figured low batery. the car ran great for a cupple days and now. 2 days later my car wont start
it ran great for the first cupple days then today i went out to start it and my remote wouldnt open the doors.
so i though the batery was dead, so i opend it with my key went to start the car and it fired up, but then died right away tryed it again and same thing happend?
seems like its not geting fuel or something but i know its not the batery cause the radeo and everything worked?
is it just a coincedence that my remote door opener dosnt work either?
any one have any ideas??

 

ps none of the windows work or the door lock from inside either.
seem like a batery but its trying to turn over so i know its not dead.

 

What type of engine management are you using? Does it have a security mode?

 

Also, check the fuel pump fuse. It is in the fuse box against the fire wall. You will have to remove all the plastic over the battery to get to this fuse box. You also have to remove some of the plastic on the cowl. It is the top fuse on the right when you get the box open. This is not the fuse box that you see right next to the battery. Once again, it is up against the fire wall.

 

its the ss box that comes with the vortec kit
split second.

 

Altenator ok? Belt on the pulley? I would think that you would know if a belt came off, but just trying to think of everything. Are you sure the battery is holding charge? Have you tried jumping it or putting a charger on it?

 

ya i looked under the hood it all looks good i think it has something to do with fuel but that wouldnt explain why none of accessories are working
and i did try to boost the car a few times so i dont think its the batery. but i hope it is.

 

if it is the fuse why would it blow
is this common?
could have i blown the ecu or something like that?

 

it was the body controle module (bcm)
but will i need to retune now that a new one is in?
