my car died!

[Faught]

hey guys i have a totaly new problem. On my way to class my 99 trans am just plain died. I had no PS no gas no PB, nothing. I got it to a stop and I had no power for accessories, radio windows nothing and the car would not even click or try to turn over. I had the idea to disconnect my mass airflow sensor, TB sensors, and the sensor on my lid, left it disconnected for about 4 min, hooked it all back up and it worked, and my SES light was off, for a while. other than not having my rear cats tunned out, the only mods i have are LT's a custom y pipe, free egr mod, and a magnaflow cat back. a couple of days ago the mesh in my MAF fell out so i cleaned it up and did not replace the mesh, would this have done it? I ran the car for 2 days no problem after the mesh fell out but i made sure nothing got in the motor. I all so just changed the oil the other day but it ran fine all that day. any way other than the SES light coming back on there has not bin an issue today, I was just wondering WTF could have made my car do this? too many codes for the SES, I know of the rear cat/o2 and egr are throwing codes but i would not think that would have done this plz help.

i took the cats out of my 01 ss and it threw the ses light on but i never had a problem with it messing with my car and i dont have a screen in my MAF either and that never messed up anything either so maybe its the EGR but idk

First check all your battery connections for loose wires or corrosion.

[Faught]

ya i went over all my electrical and it all checked out

[Cutlass]

sure sounds like loose battery cables.

[tatertot91]

Sounds stupid but have you checked your voltage?

i though of that this morning but it was fine but on my way home it was between 13 and 14 volts, on the dash but when i checked it w/ a volt meter it was at 12.3 but at least it is running fine, i have had no symptoms yet

[bigrondownhiller]

12.3 is too low. Where did you check it? Does it go up with rpm's?

[Faught]

12.3 is too low. Where did you check it? Does it go up with rpm's?

checked the bat itself, and how is it too low everything runs on a 12 volt system doesn't it? and no it does not go up w/ rpms

edit. just re checked it like 4 times lol its at 12.68

[bigrondownhiller]

Is that with the car running? Should be 13-14 with the car running.

[Faught]

not running its at 12.68

[Cutlass]

That voltage is ok when the engine isn't running. With the engine running it should be 13-14 volts

[JayTA98]

when you idle it should drop a bit but when you are driving it should be around 13 - 14 volts. Also check the wires real good. I had a bad wiere and it looked fine from the outside but it had like 3 inches of corrosion in the inside.

running your car with the MAF de-screened is fine. it will not affect the drivability of your car. like others have said check all the electrical and make sure (if this happens again), that you take note of what if anything the fuel pump is doing as well. IE priming when you turn to accessories, etc., to make sure you arent having fuels issues too.

[Too Fast]

Sure sounds like a battery or battery connection issue. That would explain the no electrical power when it died. Maybe it got jiggled then the connection was made again, and it is ok now until it gets moved.

No the mesh for the MAF didn't cause any of that.

When you say you checked it out - did you remove the battery cables, remove the alternator hot lead, remove the ground connection, clean all and re-install?

yes sir, and so far no problems to speak of

[DaddySS]

The hot lead goes from the battery to Junction block 1, then to junction block 2, the ignition "maxifuse", then splits, one lead to the starter relay, one to power distribution, and one to ignition switch. From the battery there are two other leads, one to the alternator and one to the starter.

From junction block two, power goes to the ignition switch run circuit, and to the ignition relay.

I would guess that if you check you connections at the junction blocks, the maxifuse, and the ignition relay you will find the problem and if not I would replace the ignition relay.
