I have a 2003 LS V6 with 174K miles. With the help of this forum, I maintain it myself and have worked through several problems (coils & plugs, PCM, degas bottle, dccv, brakes, etc. ... Thanks, Guys!). Sorry for the long post, but I've learned it's usually best to give plenty of info.
Until 3 days ago, the car was running great; then, without warning, the engine died suddenly apprx 2 seconds after I cranked it from cold. That's the first time I remember it ever doing that. Normally, it cranks immediately and idles without problem. I tried immediately to start it again but it wouldn't; it cranked but wouldn't start ... as though the starter was working but there was no ignition. I tried immediately again and it started and I drove it for the rest of the day without a problem (30 minute trips). Since then, the problem has gotten progressively worse. Tonight it starts so unreliably that I don't trust it for a drive.
Here's what I've noticed since symptoms began 3 days ago.
1. When it will start, it seems to run and drive normally.
2. My OBDII code reader indicates there are no stored DTC's and everything is normal.
3. The odometer display shows SRVC (P).
4. With the headlight switch in the off position (12 o'clock position) and the ignition switch turned to the "on" position (but the engine not started), the headlights flash on and off apparently randomly. I didn't notice any other running lights with this behavior, but definitely the headlights.
5. This car has the electric emergency brake. Since I seldom use it, the light isn't usually on. Now the light sometimes stays on randomly.
6. Turn signal indicators in the cockpit work intermittently ... sometimes work normally but other times seem to blink unreliably. IOW, instead of regular "blink - blink - blink," they just blink once.
7. "Blinking red light" sensor in the center of the dash at the base of the windshield flashes erratically while I'm driving.
I always try to search for existing answers before posting a new question but I couldn't find anything that sounded like an answer to this.
As always, thanks in advance for your help!
