Guest nevarmore Posted May 25, 2003 Report Share Posted May 25, 2003 Ok ~5:30PM bought new air filter (generic ricer cone) @ autozone. installed in parking lot. ~7:00PM crusing down I-76 noticed the engine running a bit sluggish ~7:15 exited to have a peek, car died at first light after the ramp. Diagnosis at home. There is fuel going to the rail, pretty sure there is spark (didnt have the wrench to check), turns over nice and strong (battery, alt, starter are good), fluids are all in range. When i crank it long (longer than i should be) exhaust smelling smoke comes out of the air filter. I pinged the entire exhaust pipe looking for obstructions and found none. Any ideas as to why a 1987 3.8 L GM motor would die in such a fashion? A friend suggested lack of fuel to the injectors. Could it be the EGR valve? I recently filled up, would "bad gas" cause these symptoms? im trying to get this going so i can do some family stuff tomorrow. any help is appreciated. Eric/Driver: if youre reading this email or call me. Quote Link to comment Share on other sites More sharing options...

Guest nevarmore Posted May 26, 2003 Report Share Posted May 26, 2003 got up to run it to AZ and have them pull codes. it died 20 feet out of my parking space. tried to pull codes by shorting the diag terminal, it flashed once then twice and code 12 = diagnostic mode and thats it. there is spark. i pulled a plug held it on the block and cranked the motor and it sparked. there is fuel up to the rail. any ideas? im abbout to clean the MAF since i just popped on a new cone filter i might have dirtied/damaged it. pleeeeze help Quote Link to comment Share on other sites More sharing options...
Nick Posted May 26, 2003 Report Share Posted May 26, 2003 You may have a crank or cam sensor ready to shit on ya. Quote Link to comment Share on other sites More sharing options...
Guest nevarmore Posted May 26, 2003 Report Share Posted May 26, 2003 Well I've narrowed it down to the fuel system, the EGR, the MAF, clogged catalytic, bad ECM, bad timing, bad cam/crank sensor. All in all at least $300 or $400 worth of shit that I can't easily fix in the apartment parking lot. She goes to a mechanic tomorrow. I fucking hate taking my car to the mechanic, but it ain't gunna go with me working on it anytime soon. Quote Link to comment Share on other sites More sharing options...
Guest nevarmore Posted May 28, 2003 Report Share Posted May 28, 2003 in case anyone cares the timing chain or one of the sprockets went. theres some plastic shit in there that goes around 90,000 miles. for those of you with GM 3.8 L motors I suggest fixing this BEFORE it breaks. $500 outta my pocket into the mechanic.
