Today I experienced the non-start problem for the 1st time of my 8 years ownership (except when battery was drained).
Every day I put about 70 miles commuting to work. This morning, when tried to start the car, it started as usual but died in 30 seconds. I then tried to restart the car. No use. I saw the battery light and the oil light on. The anti-theft led on the dash was flinking like crazy.
I checked the oil level. It's right at the mid between high and low. It's not even 3000 miles since last oil change. The battery is fairly new for only 3 months. The lights, audio and everything seems to work fine.
I know I have an O2 sensor almost gone, because recently I frequently got P0153/P1151 codes up. I had bought the right sensor but yet to put that in. So I took out my
Actron CP9135 OBDII AutoScanner. As usual, P0153/P1151 showed up. After erasing them, with the scanner still attached, the car started at one try. I then detached the scanner, tried to start again. No luck. Re-attaching the scanner, the car started like normal, fast and strong.
I tried several times with and without the scanner. With the scanner the car works great. Without the scanner the car won't even start. If the car started with the scanner and then remove the scanner whiling running, the engine dies immediately.
This is really strange. After I read some posts here, I was wondering if PATS is getting in the way since the alarm LED blinks so quickly when the key is inserted.
Since I needed to catch the last bus, I left home with another car. I will try to disconnect the battery after I got home to clear the computer.
Thanks for any help!
