Long time no see everyone! Been a long while since I had to post a problem, but did I have a weird one the other day.

Coming back from the store and I turned onto the service road, well I gave it some gas, maybe half pedel and the traction control instantly came on and the motor did not power up. Almost seemed like the motor went down in power (like it does for a split second before it kicks in) and never came up until I lifted all the way, and gave it 1/4 pedel and it took off. Got home, was there for about 2 hours, went back to the car to go to a friends and the car would not start. Had all electronics and heard the fuel pump when I turned the key, but nothing else. Checked the codes and nothing! So, I decided to check the fuses. All fuses were good under the hood. Jumped into the footwell and as I took out either fuse 23 or 25 (I think it was 25), it was fine, put it back in and heard a bunch of clicking. Tried to start the car and it fired right up. I had been trying the car after pulling and replacing any fuse that had to do with the ignition, bcm, pcm, anything engine wise. For instance, a seat fuse, I didnt try to start the car after I checked it. Havent had a problem since and this was 3 weeks ago.

This morning, I left the house for work and at a certain road I gunned it, same thing, half a pedel, this time it powered up, little spin of tires, not much at all, but I heard a bunch of clicking coming from the footwell. I am going to go try to start the car here in a little bit and see what happens. That clicking could have been there the first time this happened, but I had the stereo up, so i dont know.

03 AE automatic.

Any idea what could cause this? Thanks for everyone's input.

 

my first thought is that your battery is low. i'm sure others will chime in with ideas too.

 

Dirty or burnt ignition switch contacts can cause strange electrical problems.

 

Good idea's. The battery I could see possibly. I will keep an eye on it. The ignition switch isnt even a year old, so I dont think thats it. I have a feeling it is in the BCM, I am hoping and praying it is simple as battery or ignition, but I have my doubts though. Thanks for the responses though, any info will help!

Oh, went out and the car started right up. Thats good, didnt feel like digging through fuses at work! LOL!!

 

The next time it doesn't start, measure the voltage at the battery terminals with a DVM, and then compare it with the battery voltage displayed on the DIC.

There shouldn't be more than a 2 or 3 tenths of a volt difference between the readings.

 

There was never any resolution posted in this thread..............

What have you checked? Tested? Measured?

 

OOOOOh...........so this isn't a NEW problem after all.

 

Man, your right Lucky, I never came back and posted to that thread. Updating it now.

I think the cleaning of the connection worked for that particular problem. I am not getting the security light this time around though.
