abew330 Posted January 18, 2007 Report Share Posted January 18, 2007 sorry this may not be the place for this topic but i need help i have (i think) the vortec 5.7 and my truck dies.. i turn it on ... it idles fine but when i put it in R or D it dies thats my current problem this all started totday.. first my battery was dead... so i replaced the batt with a new one... everything was fine for 5 mins ( i took it around the block a few times ) then the same problem happened. it dies... i took it in to CSK auto and they tested my charging system and there little thingy device said my battery was unstable how can this be if the batt is new and just bought from CSK auto i told them that i just got the batt (the guy knows i did cuz he saw me) i took it to the dealer and they told me it could maybe be the fuel injectors... ( $130 to fix) but i know i can do the work.. but my question is can you physically take out the fuel injector and clean it with some type of cleaner?? i got some BG products for the tank and the TB cleaner which ima do tomorrow but what else could be killing my truck? somebody help!!!

montanass Posted January 18, 2007 Report Share Posted January 18, 2007 (edited) sounds like you might have some problems with the PCM. Is it throwing any trouble codes besides the battery? If your injectors are messing up, you should have some sort of a code. Edited January 18, 2007 by montanass (see edit history) Quote Link to comment Share on other sites More sharing options...
abew330 Posted January 18, 2007 Author Report Share Posted January 18, 2007 what is the PCM??? no codes at all... wait.. the ONLY thing was the light for my battery.. which was dead.. thats why i replaced.. but after replacing still the same problem.. tomorrow ima try to clean the TB and throw in some bbk fuel thing sounds like you might have some problems with the PCM.

Its a little computer that controlls your engine, transmission, etc. Maybe have your alternator checked. If that is bad your battery will drain quickly and the truck could possibly die. Does it act like there is no power (engine doesn't have any go)? If that is the case you are missing one or more of three important things that your engine needs to run. (fuel, air, spark) I had a situation with a '95 dodge once, it would run fine for a while and then loose almost all power. The local dealership told me it was either the injectors or the fuel pump. I had a service tech test the fuel pressure and it was way low, so that ruled out the injectors and i put a new fuel pump in it. (i had to lift the bed up to remove the stupid pump in the tank) I would start by checking the simple things, alternator, fuel pressure, air filter, etc. Edited January 18, 2007 by montanass (see edit history) Quote Link to comment Share on other sites More sharing options...

montanass Posted January 18, 2007 Report Share Posted January 18, 2007 you'd be better off to take it to a dealership and have them test the fuel pressure. Either that or you can buy a fuel pressure gauge... Quote Link to comment Share on other sites More sharing options...

PladdPezzPunk Posted January 19, 2007 Report Share Posted January 19, 2007 if you take the injectors out, you will see little filter screens in there. you can replace them without replacing the entire injector. standard motor products sells these. check to see if their clogged first though.
