QuestionQUESTION: I have a 96 chrys cirrus 2.5L V6 with 157k on it. Bought it from my aunt, it had sat for 3 years. she parked it because it was suspected of needing a distributor. she said sometimes it would run rough, sometimes die. it would do that, run well for quite a week or a couple months, and act up again. so she bought a blazer...well, started up right away, no knocks. ran pretty well. quiet. drove it 2 hours to home. it lurched a little right before it died on the freeway. wont start. We thought there was no spark, removed distributor, tested everything. everything spec'd out. cleaned rotor, contacts. it looked decent...it now appears we do have spark. and we do have fuel at the rail. checked all fuses. intact. still wont start, but it acts like it wants to... we do get some combustion, as some exhaust is created.... Any advice? I am lost...thank you for taking time to help me with this problem!
ANSWER: Any fault codes?

QUESTION: no fault codes. just 12 and 55... i disconnected a battery terminal thinking it might reset something and start... i did this several days ago. would it have erased the code?
ANSWER: Yes,
That erases the codes except the 12 is set. So try to start it a few times and see if anything other than those two shows up. You would also do well to charge the battery if it won't start. The fuel may be stale too, so if the tank is low why not add some fresh gas?

QUESTION: ok so i changed the front 3 plugs to platinum NGKs... would not start that day... but three days later, after cranking for about 15 seconds, it started!! now it is running, but does not like to start. it is running smoothly, however, if you punch the gas, it tries to die, but doesnt. if u ease your foot on the gas, it runs smoothly, i only run it up to 2000 rpms just briefly. still no codes, no check engine light. could it truly be the plugs? as i said, i only changed three of them. i believe the others are copper core autolites. thank you so much. you've been a great help!
AnswerHi Jayson,
Now that you can start it, I would shift my attention to the mixture, especially when idling/accelerating. One of the chief culprits is the exhaust gas recirculation valve. Look for that in pipe that crosses over from the front exhaust manifold to the throttle body. It is below the oil filler cap area and is mounted horizontally. The body of the valve is in the pipe, there is a vacuum operated device on the top of it, and in between a flange which is hiding the valve stem which is a rod with a slot. Put the tip of a screwdriver in the slot and move the stem back and forth to note if the valve closes to a dead stop via internal spring action. If it fails to do so, or seems sticky, then spray some WD-40 on the stem where it enters the body and then work the stem some more.
If that valve is sticking ajar you will have a hard time starting and accelerating.
