When I was pulling up to my friends house my car started running really loud, (almost like when your turbo is out, and i think mine is on the way)
I pulled it over and stopped after a few seconds and turned off the ignition. The motor began to diesel, and was shaking and trying to run at a very low rpm, the car took a while to finally turn off and when it did it would not crank, and the battery died all the way soon after. Any ideas on what could cause grinding sound, dieseling, and electrical failure?

 

wow...


man was the CEL blinking?
part of it might be bad coilpack - get codes ASAP & dont drive..

 

Dead alternator. Almost positive. The "dieseling" was probably the fuel system struggling to get enough power to work and then it finally quit. The lack of fuel /lean condition probably caused a knocking sound and sputtering. I'd look into the charging system and if it'sfaulty,get a new battery and alternator. I say battery too because if it is weak it will put extra strain on the charging system and cause it to fail again sooner than normal.


I read your post again and the loud noise you heard initially could have been the alternator bearingsgoing bad and/or the belt slipping on it causing it to break. Have you looked to see if the serp. belt is still intact?

 

thanks for the info guys, i pulled my battery and im charging it right now, i think it could be alternator too... if i can ill scan and get codes after the battery is charged, if not ill keep postin

 

Charged battery up and i got everything working again, lights, radio, locks, etc, the car just wont crank at all and voltage drops just the tiniest bit when i do that. still thinkin dead alternator? cuz i think thats what it is too now ill keep posted and if you guys have more ideas let me know
