Question about 2003 Pontiac Sunfire
Hi I have a 2003 pontiac sunfire that won't start whenever it feels like it, it is becoming very annoying, it sometimes will take just 3-4 diffrent times to crank or some times until the battery can't take it any more. I took it to the GM dealership and they don't know what the problem is, there are no codes in the system and the fuel pump pressure is good even when it was acting up. They mentioned something about the security system thinking that it is not recognizing the key or so bur I highly doubt that because the key that my car has there's no chip in it. I would really appreciate if any suggestions can be given to me, thank you in advance.
When this occurs locate the crankshaft position sensor mounted somewhere on the bell housing ,take a small hammer and lightly tap it while someone cranks the car over if it fires right up you got your culprit,sometimes this will work and sometimes not but the only way to test this sensor is with a graphing multimeter a good shop should be able to test this for you( you can also see if the car has spark when this problem is occurring by pulling a spark plug wire and laying it close to a good ground, or plug a test spark plug in the wire and ground it with the supplied lead, if you have no spark this sensor can also be your problem . these problems can be annoying and hard to locate but give this a try i have a good feeling about this one ;) please rate
