QuestionQUESTION: I have a 2001 blazer that starts wen it wants to start. sometimes it will die on me while driving down the road then not start back up. Ill let it sit for several hours and it will fire right up. The other day it wouldnt start so i had to get it towed, then wen i got it home it started rite up like nothin happened. I think i might have to change the crank sensor. Some advice on this subject would be greatly appreciated.
ANSWER: HI MIKE, WHEN THIS ENGINE DIES HAVE YOU CHECKED TO SEE IF THERE IS ANY SPARK OR FUEL ??? I CAN TELL YOU A HAVE HAD MANY BAD IGNITION COILS ON THIS ENG. SITS ON PASS SIDE OF INTAKE MANIFOLD, THEY HEAT UP AND ENG DIES..YOU MAY ALSO BE CORRECT ON A CRANK SENSOR,BUT ON THIS ENG IT IS RARE..WHEN THIS HAPPENS, IF YOU HAVE A SCAN TOOL YOU COULD GO INTO THE LIVE DATA AND CRANK THE ENG OVER TO SEE IF YOU ARE GETTING A CRANK SIGNAL,IF SO, THEN WE KNOW THE CRANK SENSOR IS GOOD. ALSO I HAVE SEEN FUEL PUMPS DO THE SAME THING AS WHAT YOURS IS DOING....SO SAVE YOURSELF SOME CASH AND CK TO SEE IF IT HAS FUEL OR IGN WHEN IT DIES..GET BACK TO ME FOR MORE INFO IF YOU WANT..OR HOW TO CK THINGS FURTHER.

QUESTION: it does seem to die when it gets hot, but i let it cool down all the way and it still wont start. also is the ignition coil very dificult to change? thank you
AnswerHI MIKE, SOMETIMES COILS WILL ACT LIKE THIS,NOT UNCOMMON. [[[STILL WOULD LIKE YOU TO CK TO SEE IF THERE IS SPARK OR FUEL BEFORE WE BLAME THE COIL.]]] THE COIL IS NOT HARD TO REPLACE,IT IS ON THE PASS SIDE OF THE INTAKE MANIFOLD,HELD ON BY A BRACKET. THE COIL HAS RIVOTS THAT HOLD IT TO THE BRACKET. JUST FOLLOW THE COIL WIRE FROM THE CENTER POSTION OF THE DIST CAP AND IT WILL TAKE YOU TO THE COIL..YOU COULD GET A COIL AND HOOK IT UP TO THE WIRE HARNESS WITHOUT REMOVING THE OLD COIL AND SEE IF IT STARTS..[[[[BUT THIS IS JUST GUESSING..]]]]DO YOU FEEL LUCKY !!!LET ME KNOW,,, I AM HERE.
