Chrysler Repair Questions? Ask a Mechanic for Answers ASAP
Hello. On your car, the fuel pump connector plugs directly into the fuel pump. the fuel pump doesn't have a wire lead, so you do not have to replace your fuel pump if you have a damaged connector. Was that what you were wondering?
Ok. I dont recall mentioning that to a previous customer, so was maybe another tech, but anyway if you are having problems with stalling and rough idle in humid weather, I would not suspect a faulty fuel pump connector. I would suspect a bad ignition coil or some other ignition component. This is only an issue during high humidity?
Ok. I don't think your problem is the fuel pump. It sounds like a misfire most likely from a cracked or otherwise damaged coil or coil boot. Have you been able to scan the computer for any codes?
yea. check it out good. Use a spray bottle and spray a mist of water at the coils with the engine running, preferably when it's dark so you can see any arcing.
Did you find the problem?
It can't hurt, but if it's only when it's very humid outside, it's usually ignition related. I assume you had the engine running when you were spraying the water at the ignition components?. At any point, did you spray anywhere in particular that caused the engine to run poorly? even if you didn't visually see sparking? This is how we usually diagnose issues like the one your having.
I don't think so. Oxygen sensors are subjected to condensation on a regular basis. What happened to make you suspect the upstream o2?
Oh, alright. I am reasonably sure it's an ignition component. Have you tried to unplug the coil wires and plug them back in one at a time until you get to one that makes no difference in the way the engine is running?
Im sorry. I thought it ran poorly and stalled all the time when it was humid outside. I misread your much earlier statement. I will open this up in case someone who has experienced this before can give you their advice.
There is a recall for the TPMS, I can email all the information in a PDF to you which includes the repair procedure, location of the trouble area and recommend repair as an additional service for 5.00 if you want. that's the lowest amount they allow. Let me know if you are interested. Its basically what the dealer would be using to address the issue.
and, you are correct in that it does come with some drivability symptoms.
I will submit an offer. after you click to accept it you will see an area to enter your personal information. enter in your email and i will email them to you right away.
The system won't allow me to do this for some reason. Never encountered this problem before. Give me just a minute.
Ok. Something is wrong with the system today, so I will post the information right here. Please save it or print it. Thanks and remember to rate me so I can get credit. Thanks again.
this is what you were referring to, right?
