Bulbs and fuses are good. Jumped brake switch. Lights still will not come on.
3.8 6cyl. Had this problem recently. To the point car stalled on road. Restarted and off I went. Said replace gas cap. Computer said change MAF sensor. That was done. Error code went away. Car does not stall, but has a rough or intermittent hesitation. Mechanic said change coil packs. Changed all. No difference, I am out another $100.00 . OK, still hesitates. Mechanic says change harmonic balancer? Sounds expensive. Only fuel used has been Chevron. Filters are all new. In order of least expensive parts to most expensive procedure what do we do next? No error codes are indicated. Thanks
Also check the fuel pressure harness attached to the fuel pressure regulator. High mileage cars may have a deteriorated line or rubber that will cause the same check gas cap message. GM part # 2450-6640.
The strong gas smell is occasional. This started about two years ago. The dealer could not find a thing when I reported it at the time of a service. At times I park the car and the area in front of engine has a strong smell of gas. Sometimes I can be driving and smell it through the vents. It can be very strong. At one friend's suggestion, I replaced the gas cap which did not make a difference. My fuel gauge's accuracy is unreliable at times. I can live with the fuel gauge inaccuracy, but the gas fumes may kill me. What do I replace next and next again?
Based on what I read on this site I need to buy a fuel pressure regulator to get rid of the occasional strong fuel smell coming through the vents and detectable outside the car near the hood. Do I need a seal kit with that from Delco or is that for something else? I assume this is a very straightforward diconnect and connect procedure, right?
Look at your manual. It is near the firewall and is difficult to see. Get a strong flashlight and and long funnel to do the job. This one is best done by the shop.
Can this be cleaned? Do I need to order an entire new wheel hub assembly or is this an easy component to change? What is the est. cost if the dealership or non dealership mechanic does the job? Thanks
