04 Armada dies randomly while driving.
We bought an 04 Armada last fall that had 150k kms on it. It's been ok so far for the most part. But recently it's been dying while the wife is driving it. At first it was on the highway in rush hour, it just quit, restarted fine then died a few minutes later down the road, fired right back up and was fine for 2-3 weeks. I scanned it with a cheapo code reader and a decent scanner and the only code that comes up is the one it's had since we bought it, it's for the vent solenoid. And of course I can't get the thing to die when I'm driving it.
A few day's ago it died again, and it fired back up like normal, was good again for a few day's until this morning. She made it 1/2 block away from home and it died then wouldn't start back up right away. It would crank over fine though. She let it sit a few mins and got it going again, took it home and took a different vehicle. I'm hoping there's a code stored this time.
I'm not going to throw random parts at this thing, I'd like to figure out wth is going on. But hard to fix if it aint broke. I haven't done anything yet. I guess the first step is to get it to die and try to pin point if it's losing fuel, spark or both. I'm hoping the thing won't start when I get home from work but that's doubtful.
Could someone point me where to look for the crank and cam sensors, I'd like to do a wiggle test with them first. This thing is pretty crusty underneath so a corroded connector is likely. Other thoughts are the ecm relay or fuel pump on it's way out.
