3.198lumina Posted December 13, 2013 Report Share Posted December 13, 2013 hey guys last nite my lumina broke down, no indication of it happening no problems , no rough running etc. the car just stalled out and when you crank to start it would sound like it would start and almost start , but it would also backfire and make gasping sounds. I had it towed to a station cause it was dark out and had no way of working on it then or getting it to start. just wondering what it could be. they haven't started to work on it yet and said it could be a few days. thanks eddie Quote Link to comment Share on other sites More sharing options...
rich17 Posted December 18, 2013 Report Share Posted December 18, 2013 It could be so many things. Probally a fuel pump tho Quote Link to comment Share on other sites More sharing options...
pshojo Posted December 18, 2013 Report Share Posted December 18, 2013 I have had this a couple times, ended up being coil pack both times. Quote Link to comment Share on other sites More sharing options...
skitchin Posted December 18, 2013 Report Share Posted December 18, 2013 Fuel pressure regulator and EGR solenoid were replaced in my case - could be anything in the fuel/spark department though. Quote Link to comment Share on other sites More sharing options...
3.198lumina Posted December 19, 2013 Author Report Share Posted December 19, 2013 yup its the coil pack/s. well they had 207,000 miles on them so I guess that wasn't too bad Quote Link to comment Share on other sites More sharing options...
3.198lumina Posted December 21, 2013 Author Report Share Posted December 21, 2013 well it isn't the coil packs. that's what they thought , before looking at the car. it does have spark across all coil packs. I am now being told it is most likely a broken timing chain. well that's all I know for now, as the place will be closed for Christmas. what is involved in doing a timing chain? from my searching on it, it could also be a broken cam shaft???? car ran fine , then it stalled and wouldn't start.... cranks and sometimes backfires.... I don't think this is going to be good:roll: was told when they try to crank it , they can hear a little slapping ... car does have 206,000 miles. thanks for any advice Quote Link to comment Share on other sites More sharing options...
rich17 Posted December 24, 2013 Report Share Posted December 24, 2013 Could be a broken cam but the they usually run on 4 cylinders. Could be the timing chain but seems unlikely. I'd hook up a computer and see if its getting a cam and crank signal first Quote Link to comment Share on other sites More sharing options...
3.198lumina Posted December 26, 2013 Author Report Share Posted December 26, 2013 well im going took the car back. they didn't want to be bothered.i don't get it. .. well im going try to do it on my own with help from the w body:biggrin: if I pull the valve cover I should be able to see if the cam broke , because some of the valves wont be moving right? rich when you said a computer did you mean like a code reader. funny thing is that nite when it broke down, I had just went to my friends house to borrow the code chip reader. I plugged it in under the dash. so after this happened , he read the code reader and there were no codes. Quote Link to comment Share on other sites More sharing options...
rich17 Posted December 27, 2013 Report Share Posted December 27, 2013 You're not looking for a code. You're looking for the proper voltage signal from the cam and crank sensors. Quote Link to comment Share on other sites More sharing options...
3.198lumina Posted January 2, 2014 Author Report Share Posted January 2, 2014 well it is a broken cam. pulled the valve cover off and only one of the lifters moves the others don't . didn't pull the back valve cover just the front . I would assume that's the same for the backside. is there a magic fix in a bottle for this one:lol: Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted January 2, 2014 Report Share Posted January 2, 2014 pull motor, replace with better cam from WOT-Tech. Quote Link to comment Share on other sites More sharing options...
rich_e777 Posted January 2, 2014 Report Share Posted January 2, 2014 Might have a broken/worn timing chain as well. You will need a pulley tool to remove the timing cover to check. Quote Link to comment Share on other sites More sharing options...
l67ss Posted January 2, 2014 Report Share Posted January 2, 2014 Mite b better off jus dropping in a good used motor. Those broke cams can b a bear to remove. Plus you dont kno what caused it to break. Quote Link to comment Share on other sites More sharing options...
mfewtrail Posted January 3, 2014 Report Share Posted January 3, 2014 A good used junkyard engine is your best bet. Completely re-gasket it before installation. Most 3X00's that have went through a broken cam do not look too nice inside and nothing short of a full rebuild would ensure that they would run reliably again.
