New issue

I was wondering if someone would be able to chime in. So, sometimes after shutting the car off, the car refuses to start. It cranks away just fine, just will not fire. During those times, I have noticed, if the parking brake is on, the brake light would be very dim. If I leave the car alone for 2-3 minutes, then it will fire right up. No driveability problems, except when it happened today, the DSC+Yellow brake light stayed on but went away once I restarted the car (This time, it fired right up).

No codes thrown. I am at my wits end. Thank for any assistance!

Also, how old is your battery? They typically have a 5 year life span (+/- 5 years), and have been known to cause weird electrical problems when they start to die.

My plugs are fine and new. The fuel filter is probably on its way out, but that would not explain the dash lights acting the way they are when the car would not start. I will take a look at the battery tomorrow since it appears to be an electrical issue. Thanks you both! If anyone has ever had anything like that happen, please chime in.

The battery was at least 5 years old. I switched it out with a new 49DL from Autozone. When I first started the car, it started immediately, but the red battery light was on. It went away after I revved the engine once. I took it for a 50 mile drive. And when I came back, I turned the car off and restarted it. It turned on without the red battery light. I guess I shall find out tomorrow if the problem is gone. I have never heard of a car react like that to a dying battery!!

Fuel pump can give erratic symptoms.

Check pressure at fuel rail.

How old are your pump and filter?

I bet it was your battery. Weird stuff happens with dying ones.

I really hope that was it. When I had it tested yesterday at Autozone, predictably they said it was perfectly fine.

And that is a scenario I read time and time again on this forum.
Then they replace the battery and all is well.

Just sayin'

I had them test my battery, too. It was 7 years old and had couldn't start a car anymore. I charged it for a while and brought it in. They said it was perfectly fine. I came home and put it back on a 2 amp charger for a few hours, then realized that it was HOT. Got the 49-DL and my car was happy again.

Yeah, wish they still made the loveable 49DL again.

We're going to miss the old standard.

Good for you!
Must have been old stock because guys from all over the country are reporting that they have been told it's discontinued. Most say no stock when they go to buy.

That really sucks! Hope I don't need one more for the next 5 years after which I am sure it will be time for a new BMW/Porsche.

Ok so that was not it. Today morning, I try to turn the car on and the dash lights did not come on. The only things that were on were the LCD and the airbag light on the dash. My stereo turned on fine. So did the cabin lights and the side marker lights when I turned the headlight switch on. The funny thing is that the car still cranks and very strongly. But of course, it does not turn on. What else could it be? If it is not the ignition switch, I am out of ideas.

It seems to me like it would be fuel related...is it every time you turn off the car?

No, only sometimes, although it has gotten more frequent lately. I doubt it is fuel related. Lack of fuel will not make the dash indicators stay off.

Well, I guess indirectly it could be fuel related. I guess the system is unable to send power to the dash lights as well as the fuel pump, which normally is powered with the key in position 2. Could the ignition switch be the culprit here?
